It was determined that the stress reversal was unique to a few eyebars because the vehicle lanes were not centered on the roadway. © 2009-2020 The Constructor. The connection at the eyebar was not redundant because it consisted of only two pairs of eyebars. A total of 46 people lost their lives due to this accident. Collapse of the Tacoma Narrows Bridge: A Case Study, Petra Jordan: A World Heritage Site Under Risk. He said the technician's condition was stable. The built-in flaw in the eyebar led to the sudden propagation of the crack when the fatigue stress exceeded its limit. College of Civil Engineering, Fuzhou University, Fuzhou, China. The experts investigated many possible causes of the collapse. Tests of different eyebars showed a consistent composition between the specimens, which indicated that the fractured eyebar was not unique. The length of the Point Pleasant Bridge was 681 m. The Point Pleasant Bridge was constructed at the cost of USD 1.2 million. When the Point Pleasant Bridge was being constructed, the knowledge of long-term fatigue combined with the crevice corrosion was limited. The rear bridge then smashed into the head bridge, which was connected to the first class cabin, ripping a door off the A330 aircraft. HONG KONG // Hong Kong authorities said they had launched an investigation after an air bridge collapsed at the city's airport, ripping the door off a Cathay Pacific plane and injuring a technician. These tests concluded that the live loads were not excessive and that the loading caused some vibrations in the individual members of the structure. We are investigating the cause of the incident," a spokesman from the Hong Kong Airport Authority said. At least three fishing boats were crushed and a fuel truck plunged into the water. Its objectives were to identify the cause of the failure of the bridge, to figure out how to fund a new bridge in an efficient manner, and to define a system of standards that would ensure the safety of the bridges in the country. You will receive a link and will create a new password via email. However, it was not large enough to allow engineers to inspect the connection. The evidence supporting failure by fatigue stress was based on changes in the live loads of the structure, which changed the orientation of the eyebars. There were two main contractors who were awarded the work. Scour was eliminated because of the observations of the divers at the scene. The construction of the Point Pleasant Bridge was undertaken with the adoption of the latest technologies and new construction materials of the time. Hong Kong leader Carrie Lam warned that what Hong Kong is experiencing now is actually worse than the 2008 global financial crisis. A similar design was used earlier in the St. Mary Bridge in West Virginia, which is also located on the Ohio river. The new procedure provided exact protocols to be followed, and inspectors were required to be evaluated and certified by the Federal Highway Administration (FHA). VIP members get additional benefits. This change of symmetry caused uneven loads across the suspension spans. The loss of one element would lead to the collapse of the bridge. Once all the survivors had been rescued, and vehicles had been recovered, the operations shifted towards the removal of the collapsed structure. Golden Gate Bridge: Construction of One of the Longest Suspension Bridges in the World, Chenab Bridge: Construction of the World’s Highest Rail Bridge, Austin Dam Failure: One of the Biggest Disasters in US History. Further verification showed that the piers were in proper orientation. The suspending eyebar chain acted as the top chord of a variable-depth stiffening truss. Eyebar chain greatly improved the bridge’s stiffness with less steel. This lack of consistency indicated that the eyebar had a more severe susceptibility to stress corrosion and hydrogen embrittlement in the harder section of the material. This limit contrasted with higher factors of safety, 2.75 and 1.75 respectively, for an alternate conventional suspension design. Thus, as soon as the tower toppled over, all the spans of the bridge collapsed because it was constructed as a continuous truss between anchorages. If the piers shifted, the towers would be out of alignment, inducing a sag in the cables. It was the holiday season and people were shuttling back and forth between the two cities via the bridge. 22nd August 2020 – (Hong Kong) At the Zhuhai Gongbei Port construction site, it is suspected that part of the pedestrian footbridge has collapsed, and Customs clearance services were once disrupted today. It was the holiday season and people were shuttling back and forth between the two cities via the bridge. The tests sought to establish the natural frequencies of the bridge and to determine the excitation created by heavy vehicle use. The bridge connected two major cities of Ohio and West Virginia, and provided direct access to their respective state capitals.

The works related to the pier foundation were carried out by the general contracting company of Pittsburgh, and the superstructure was constructed by the American bridge company of Pittsburgh. Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University, Hong Kong, China. All affected passengers had left Hong Kong by Monday morning on alternative flight arrangements, she added. The format categorizes the superstructure, the substructure, and the deck of the bridge into a set range of values. Each bridge was to be inspected every two years. To verify the fact that dynamic effects were not a factor leading to the collapse, vibration response, and dynamic stress amplification tests were performed on the St. Mary’s Bridge. The bridge was designed using the deflection theory. On 15th December 1967, the Point Pleasant Bridge collapsed due to heavy traffic on the bridge.

Plagued by the collapse of travel amid the coronavirus pandemic, arrivals to Hong Kong plummeted nearly 94 per cent year on year in 2020 to just 3.57 … It was wide enough to provide an air space for pollutants to attack the steel. The hardness was not uniform throughout the thickness of the material. In 1996, the FHA created the nondestructive evaluation center in McLean, Virginia. The linkage of the eyebar chains to the suspension cables by a pin created a section of the material that could not be protected by paint. However, the steel used was of unusually high strength, and its properties were not well known. Also, the bridge was not designed with a sufficient number of redundancies. The system of inspection is broken down into a standard procedure. A 140-meter (459-foot) bridge has collapsed in northeast Taiwan, sending an oil tanker in the water and killing at least two people in fishing boats below. "No passengers or crew members were on the air bridge at the time. The importance of this standardization is to allow the accurate rating and comparison of the bridges in the inventory. This exceedance would cause the eyebar to detach from the pin, allowing the connection to rotate and thus cause the collapse. The Hong Kong–Zhuhai–Macau Bridge (HZMB) is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands.It is both the longest sea crossing and the longest open-sea fixed link in the world. Plagued by the collapse of travel amid the coronavirus pandemic, arrivals to Hong Kong plummeted nearly 94% year on … Calculations showed a 3% loss of steel due to this degradation of material. The Point Pleasant Bridge was a suspension bridge. This theory implied that the pin cap would become responsible for resisting the lateral forces within the connection. The substructure of the bridge was lacking the structural redundancy. The combination of uneven loading and changes in stress levels caused the pins to shift. The traffic on the bridge was crawling. Lost your password? The next morning, the bridge authorities closed the bridge for traffic after noticing that the bridge was undergoing severe undulating motions. It first verified with the military that no airplanes had passed through the vicinity at the time of the collapse. A sidewalk and a vehicle lane on the south side, instead of two vehicle lanes on the north end, caused this lack of symmetry. TAIPEI: Taiwanese rescuers on Thursday (Oct 3) retrieved the body of the last missing person killed when a bridge collapsed two days ago, smashing onto fishing boats moored underneath. The U.S. Bureau of Standards noted the fracture pattern on the eyebar. One feature considered to be potentially faulty was the substructure of the bridge. The twitterverse is showing the damage done at Hong Kong airport in a double airbridge collapse early last night. A higher, not lower, factor of safety should have been used for this bridge. However, there was no evidence that calculations were made for the correct dynamic loading.

It was first conceived … A Cathay spokeswoman said its aircraft was "slightly damaged" but would not comment on whether the home carrier will seek compensation from the airport authorities. One opinion cited evidence for fatigue stress, whereas another one explained the cause as a combination of stress corrosion and corrosion fatigue. The brittleness of the steel connection, and thus its susceptibility to sudden fracture, was enhanced by two factors. The National Bridge Inspection Standards were created in response to the collapse. A total of six fishing workers from Indonesia and the Philippines were killed in the incident, which also left 12 … Read more.. This shift could have been induced by sediments around the piers being washed away (known as scour), a deficiency in the foundation that would cause the anchors and piers to move, or an impact to the piers from a water vessel. The six-lane, Hong Kong-Zhuhai-Macau Bridge is 34 miles long and includes an underwater tunnel that goes for four miles. The following points describe the key lessons from the failure of the Point Pleasant Bridge: A total of 46 people died due to the collapse of the Point Pleasant Bridge. Towers of the bridge were supported on the rockers. Live loads produced by a heavy vehicle would cause the hole in the eyebar to be placed in tension. In 1968, the U.S. federal government enacted a procedure for national bridge inspection. Please follow the instructions below to allow notifications to be sent from The National. The design was also evaluated, and the bridge did not provide any redundancy in the structural members that connected the suspension chain to the eyebars. The roof of Cellar Vall Llach, one of the leading wineries in Priorat, has collapsed due to heavy snows potentially destroying what remains of the 2018, 2019 and new 2020 vintages. UP NEXT. A different theory of the collapse found support in the metallurgical aspects of the eyebar chains and the consequence of both loading and the environment on the steel. When the first eyebar failed, the entire connection was rotated and got separated from the eyebar. The design of the bridge was unique because it had high tension eyebar chains, rocker towers, and a unique anchorage system. Beyond the Headlines: will Azerbaijan's victory in Nagorno-Karabakh lead to lasting peace? When around three big trucks and 72 cars came to a halt, the bridge began to sway wildly and ultimately collapsed. 1. The 41 … One of these, it appeared, had grown into the 33 mm flaw that had initiated the fracture. Point Pleasant Bridge, also known as Silver Bridge, was constructed over the Ohio River to provide the crossing for highway number-35 of the United States of America. The other factor was the low temperature that on the day of the collapse, was near to freezing temperature. This failure caused the Ohio tower to fall and resulted in the collapse of the West Virginia tower. As the loads redistributed in the eyebar chain, the eyebar heads and the connecting pins would rotate. The bridge was constructed as a continuous truss between anchorages. The exposed surface was thus left open to natural elements and created a built-in weakness. The reaction most prevalent to the cause of the collapse was found in the eyebar chains and pins. However, different opinions surfaced to justify the cause of this fracture. Become VIP Member. The construction of the bridge started in 1920 and completed in 1928. A team assembled to look into the accident on the multibillion-dollar Hong Kong-Zhuhai-Macau bridge which killed two workers and injured three … The oil tanker that was traversing the bridge at the time fell into the water and caused a fire when it struck three fishing boats that were below the bridge.

A towering bridge over a bay in eastern Taiwan has collapsed sending an oil tanker truck falling onto boats in the water below. Some of them are discussed below: The U.S. Army Ordnance Group ruled out the possibilities of explosions and impacts. Inspection of the wreckage showed corrosion in many sections of the bridge. Stress concentration and fatigue can be a dangerous combination to cause the failure of a bridge. Beyond the Headlines: will vaccines help us return to normal in 2021? This sag would change the load distribution throughout the structure. A truck driver and teenage girl are killed when suspension cables snap on a French bridge, with prosecutors saying the deadly collapse was apparently caused by … The vehicles removed from the wreckage were checked for explosives, and structural members were inspected for signs of damage due to explosives. Rocker towers were hinged at the bases to accommodate thermal deformations. What are the Installations Required in a Tunnel? The bridge collapsed about 9:30 a.m. in Nanfangao, a tiny but often-crowded Pacific coast fishing village. Before this law, bridges were not consistently inspected. The eyebar would still be vulnerable to failure even if the resulting stress did not exceed the yield strength of the material. VIP members get additional benefits. Collapse of the Tacoma Narrows Bridge. In Taiwan, a huge 140 meter (459 feet) bridge collapsed in October of 2019, the event is known as the “Taiwan Bridge Collapse”. The narrow gap between the eyebar and the connecting pin made the problem worse. The composition of the atmosphere also played a critical role in the state of the steel. The center span broke and flipped over into the water below, carrying 64 people from the roadway. Point Pleasant Bridge Disaster: Collapse of the Eyebar-Chain Suspension Bridge, Mackinac Bridge: Construction of the Most Aerodynamically Stable Suspension Bridge. When the bridge was designed, the loading was based on the American Association of State Highway and Transportation Officials (AASHTO) H-15 specifications for a 15-ton truck with 106 kN on the rear axle and 27 kN on the front axle. Design features also indicated that the towers were protected from possible contact with a vehicle. They reported no holes around the piers or any signs of damage to the piers.
