Construction sequence analysis of the flat plate system in a high‐rise building and its impact on the construction cycle

Abstract

Abstract A construction sequence tends to influence the short‐term and long‐term behaviours of flat plate and flat slab systems, especially as it relates to serviceability conditions and, in some occasion, to strength‐related issues. Present material technologies, especially as it relates to high‐performance concrete (HPC), may have positive influence on the construction sequence and planning of these systems. Proper precautions in construction practice nowadays is required as it may influence the behaviour positively and improve the serviceability behaviour, especially as it relates to cracking and stiffness control because of the use of HPC. The purpose of this paper was to study the behaviour of flat plate/slab system behaviour when utilizing HPC during construction and their impact on the long‐term performance of these systems. Through this study, several construction sequence analyses were performed by considering the effect of slab strength and stiffness development during construction cycle, shoring member stiffness and the cracking effects on the long‐ and short‐term behaviours. Also, it was performed to study different shoring methods of a high‐rise building system with a flat plate floor system as it may influence a typical floor construction cycle and overall construction schedule in a high‐rise building.
