His cavalier attitude, which was common among workers at the time, would be gone forever, and he would also develop a heartfelt passion that still resonates today. In the warmer weather snakes may be found in public areas around Hobsons Bay, including in some parks and reserves. But when they went to connect the two spans, they discovered there was a vertical gap of 115 mm between them. The buckle occurred because of the decision to lift each half-span separately - each half-span was more flexible than when they were connected together. It was like slow motion.
Eventually, they selected the same method to relieve the buckle as they used on the east span — they would remove bolts from the joints, relieve the stress, and straighten the buckle. The girders started to turn blue. . The assembly of the span then sat dormant for one month while they decided what to do next. Despite this, the lift went ahead. But once you start removing bolts from the top flange of a bridge, its ability to carry load decreases. While this wasn't the initial cause of the tragedy, the way in which it was remedied did prove part of the problem.
Almost as soon as he put the phone down, Gerit Hardenberg heard the low rumbling sound coming across the river. It is said by students that they are to remind engineers of the consequences of their errors. Vincent Rosewarne, a 24-year-old crane operator, suffered broken arms and a fractured leg after riding the broken span to the ground. A proposed grand gateway, it was to connect the west with the east; link the industries, docks and fruit and vegetable markets with the city and the wealthier suburbs. Take our to determine if you are doing all you can to ensure the safety of your workers.
John Holland Construction, which had no previous experience in working with box girders, then transferred responsibility for many engineering decisions to the company, Freeman Fox, who had also been responsible for the collapsed bridge in Wales. There have also been allegations that at this time many construction flaws were not understood as they would be today, or worse still, that they were simply ignored due to construction being behind schedule. After spending his time helping to carry the injured and dead and also dig out the missing workers, it was only when he collapsed with exhaustion that he was revived and told to go home. This time they got away with it. This flexibility or lack of stiffness allowed the buckle to occur. The left-hand half-span began to drop downwards. West Gate Bridge, Melbourne Characteristics Design Box girder and cable stay Total length 2,582.
What were the Royal Commission findings? This remedy only caused another problem, however, when the placement of the kentledge caused a buckle in the upper flange, one of the ribs that support the bridge. The bridge was coming down and I thought I had no hope.

The two main causes of bridge failure, wind loads and improper design or design flaws, will be discussed with examples like the Tacoma bridge collapse of 1940 and the I-35 Mississippi River bridge collapse of 2007 later on in the paper 4, 1. The West Gate Bridge spans 2.
Then there was a great cracking sound and everything was falling. Homes were spattered with flying mud. Many workers were in fact reluctant to leave the site, determined to dig out those who were buried beneath the rubble and debris. More than 150,000 vehicles cross the bridge each day. A royal commission to investigate the cause of the collapse attributed the failure to a litany of errors in the structural design and method of erection of the bridge. Before the October collapse, two half girders on the western side of the bridge had been brought close together and it was found that there was a difference of about 4.
The bridge collapsed over a large river called the Yarkon River. Instead they pointed the finger at two primary causes. The rescue teams found 32 bodies that day. News Just before lunch on Thursday 15th October 1970, the West Gate Bridge suddenly groaned. An eerie pinging noise filled the air. A Royal Commission into the disaster found the design of the bridge and the construction method used to be at fault for the collapse.
Many lucky workers who rode the span to the ground survived the impact: an impact heard and felt as far as 20km away. Engineers proposed putting ten concrete blocks, each weighing about 8 tons, onto the girders to bend them into the correct position. West Gate Bridge Design Box girder and cable stay Total length 2,582. There was nothing I could do for the dead men. When the rescue workers arrived he was covered in oil and mud and visibly weakened, yet he politely shrugged off the rescue workers' help for himself. It was only after some time, once expert rescue workers had managed to gain some semblance of order amidst the chaos, that workers could be persuaded to return to concerned family and friends who had been waiting beyond the cordon. It was the removal of these bolts which caused the bridge to collapse.
He was taken to the operating theatre. But the gap of 115 mm on the west span was too large for the jacks to close, so they made the decision to place 51 t of large concrete blocks on one half-span to weigh it down and close the gap. Among the hundreds of photographs are pictures before the bridge's collapse — 45 years ago today — which killed 35 workers. The West Gate Bridge, with all its promised glory, had been under construction for some two years by that stage. A tragedy like this should not and must not ever happen again.
