Abstract:
Aiming at the problems of low construction efficiency and large amount of on-site wet work in the cast-in-place layer of traditional composite floor in concrete modular buildings, a separate floor system composed of embedded steel bars, on-site lap steel bars and cast-in-place ultra-high performance concrete( UHPC )was proposed to replace the conventional cast-in-place layer. Taking a 28-story dormitory building as an example, the modular design was carried out. The overall finite element model considering the axial, in-plane shear and out-of-plane shear stiffness of the joints was established. The structural response of the structure under the combination of wind load and seismic load was analyzed, and the parametric analysis of the stiffness of the joints in different directions was systematically carried out. The results show that the maximum values of story drift and story drift ratio of discrete diaphragm system under the combination of horizontal loads do not exceed the code limits. The maximum value of the floor shear force occurs in the bottom floor of the structure, and the maximum value is 9 300 kN. Under horizontal loads, the distributed joints are primarily subjected to axial forces and in-plane shear forces. Structural story drift and story drift ratio could meet the requirements of the codes when the axial stiffness of the joint exceeds 1×105 kN·m-1 and the in-plane shear stiffness exceeds 3×104 kN·m-1. The proposed discrete diaphragm system employing distributed horizontal connection joints can significantly enhance construction efficiency while ensuring structural safety, making it suitable for high-rise concrete modular buildings and providing valuable design references and a theoretical basis for similar projects.
