Abstract
The evaluation of construction load is a critical issue in the design and construction of long-span flat plates, which are vulnerable to excessive deflections and concrete cracking. This study focused on the effects of shore stiffness and concrete cracking on the distribution and magnitude of the slab construction load. Slabs connected by shores were idealized as a simplified multi-story frame model, which was used to develop a simplified method for the evaluation of construction load. In the proposed method, the effects of various design parameters, including shore stiffness, concrete cracking, and boundary conditions, were considered. The proposed method was applied to an actual multi-story building under construction. The predicted shore forces and construction loads were compared with the on-site measured data and predictions front existing methods.
