EVALUATION OF L'AMBIENCE PLAZA POSTTENSIONED FLOOR SLABS

Evaluation of a 16-story building's (in Bridgebort, Connecticut) floor lift slabs under ideal and less than ideal lifting conditions is summarized. The evaluation is based on results from hand computations for commonly used continuous beam models representing strips of the 2-way slab system, and on results from comprehensive and detailed finite element analyses. The study found that anamolous design details of the posttensioning tendons could be considered a possible cause that initiated failure or, at a minimum, were a major factor in the propagation of the collapse after it had begun, even if the National Bureau of Standards most-probable-case scenario is accepted. The specific findings of the study are presented and discussed.
