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. A common issue in design and construction results from the way light can reflect and even amplify off glass and metal. Throughout history, the structural failures and sub-standard use of construction materials can experience in the long run, but the results are very devastating. Which is the code used for the design of the RCC Bridge? The most probable reason for the collapse of the building was the punching shear failure on the 23rd floor of the building. 22 0 obj The Washington Post reported Friday that an engineer called the state to report cracking two days . >> << /Annots [32 0 R 33 0 R] The incident occurred while concrete was being poured on the third floor of one building. /LastChar 121 Structural Failures: A Case Study Researched by: Ronald O.

Distortion and damage from the superstructure is appearing due to the failure. The result can be irreparable damage such as concrete slab shifting and settling, cracks on foundation walls, shifting of the foundation structures, and/or loss of structural support of framing members. The giant cross-lot braces that spanned the entire lot permitted construction to proceed without interruption. Society is fortunate that in most countries, complete building collapses are a relatively rare occurrence. /F7 26 0 R The building design was of a reinforced concrete flat plate with a 200 mm thick concrete slab. >> /F10 37 0 R Danger would emerge only if there had been something like a void or a sinkhole that had caused one or several piles to settle downward and left the others unchanged. The bridge was famous for the way it swayed, twisted and dipped during heavy winds. The structural framework included the construction of load-bearing walls and each floor was directly stacked onto the walls.
