Construction safety of multistory concrete buildings

It is noted that for a building constructed at a fast rate, in which the shoring and reshoring system is employed and the partially stiffened concrete slabs are used frequently as load-carrying elements during construction, the safety of the building becomes an important issue for investigation. The failure of the building may be taken to correspond to the failure of the concrete slabs. The study covers the limit sate functions for a reliability analysis, and structural analysis performed using the 'improved' method in which the deflection approach is used to compute the load effects. The failure probability is computed using Monte Carlo simulation. A parametric study is performed to investigate the effect of concrete strength, spacing of forms and the construction cycle length on the construction safety.
