Construction is perhaps the most critical stage in the life cycle of structures, mainly because of the danger of failure and the high chances of underestimating construction loads. During construction, the blue reflective glass used for the building started to fall off from various heights, forcing police to close off the area around the building. /FirstChar 32 Cracks were observed in both exterior and interior walls. /LastChar 57 These stages were, failure due to punching shear in the rooftop at section E5, the failure of the slab, and in the end, the progressive failure of the structure. When a 40 mph wind struck on November 7, 1940, the bridge started to twist and buck wildly. The floors settled, and the ceilings and walls cracked, and even the elevator got stuck as its shaft got deformed and would not permit free movement of the cab. The girders, though, were only one-third the height of the originally proposed trusses, which resulted in a disproportionate depth-to-width ratio. Hamburger, SE Structure Name: . This impacted the floors beneath and obliterated the entire corner of the structure. Settlement can be tolerated by the structure provided the loads do not exceed the allowable bearing pressures.
