Analytical Procedure for Timber−Concrete Composite (TCC) System with Mechanical Connectors

In the construction of modern multi-storey mass timber structures, a composite floor system commonly specified by structural engineers is timber–concrete (TCC) system, where beam or panel (MTP) connected to concrete slab with mechanical connectors. The design TCC systems has not been addressed in standards due lack suitable analytical models for predicting serviceability and safety performance these systems. Moreover, interlayer connection properties have large influence on system. These are often generated testing. this paper, an approach designing proposed that incorporates predict from basic component such as embedment withdrawal strength/stiffness connector, thereby circumventing need perform tests. leads calculation effective bending stiffness, forces connectors, extreme stresses can be used evaluate allowable spans under specific loads criteria. An extensive parametric analysis was also conducted following procedure investigate behaviour. It observed screw spacing thickness remain most important parameters which significantly
