Abstract
The current research investigates the impact of using staged-construction analysis (SCA) of HRB on the behaviour of PT slabs as a more realistic approach for HRB analysis. Comprehensive finite element models (FEM) are developed to conduct SCA of HRBs with PT slabs having various heights and layouts. The FEM accounts for both geometric and material nonlinearities while including prestressing loads. Hence, PT slab analysis is conducted using 3D modelling of a complete building rather than 2D modelling. A series of analysis comparisons is made between OSA, SCA, and SCA with time-dependent effects (SCAT). Then, comparisons between the three analyses are made to evaluate the design of PT slabs during service and ultimate stages due to the different analysis approaches.
