| Abstract: |
The expansion of a casino entertainment complex in the eastern United States was progressing in 2003, when a collapse of an approximate 15 by 60 m area of the parking garage occurred during placement of cast-in-place concrete at an upper garage level. Garage construction generally consisted of stay-in-place, precast, prestressed concrete formwork and cast-in-place composite slab system connected with mild steel reinforcing to cast-in-place concrete columns and shearwalls.. Collapse of multiple levels of the composite floor system occurred, but nearly all perimeter columns and shearwalls in the area remained standing. The authors were retained to investigate and determine the cause of the failure and study the progressive collapse. The investigation results were used to successfully assess failure cause and make recommendations on how to avoid such accidents in the future. |
