However, the existing adjacent structures had only single-level basements. The curved design of the Vdara Hotel in Las Vegas, designed by Rafael Violy, basically turned the building into a giant magnifying glass, intensifying light so much that it harmed hotel guests and earned it the nickname "Death Ray Hotel.". On the 23rd floor, the slab started showing cracks and the failure of the building occurred vertically along the full height of the building, including the basement levels.

In his report, Adeoye (1998) noted that between December 1976 and January 1995, there were over 30 cases of collapse of buildings reported across the country, with well over 250 persons losing their lives and several others being severely injured. One can speculate that a geotechnical engineering study of 2D slope stability conditions could have predicted this failure based on the slope geometry and soil type. It led to a root and branch review of the cause, changes in codes of practice and the discovery of many buildings that had to be strengthened to prevent repetition of such a catastrophe. 0 0 0 0 0 0 0 0 0 0 Construction is one of the most critical phases in the life cycle of buildings due to the risk of failure and the possibility of underestimating construction loads. /Annots [32 0 R 33 0 R] Sorry, you do not have permission to ask a question, You must log in to ask a question.
