Abstract

Since the reform and opening up, the national economy has experienced unprecedented development; however, along with the rapid economic development, the environmental and sustainable development problems behind it have become more and more prominent. Compared with the assembled reinforced concrete structure, prefabricated hollow core slabs, due to its mechanical properties superior to cast-in-place solid concrete, acoustic insulation and thermal insulation capabilities, and as a very common horizontal force components and is widely used, while in the multi-storey residential buildings, the use of prefabricated hollow core slabs also effectively reduces the structural dead weight, effectively improving the overall seismic performance of the structure. The objective of this study is to investigate the seismic performance of prefabricated hollow core slabs used as walls and to propose a nodal connection method for assembled hollow core slab walls composed of prefabricated hollow core slabs when placed vertically. The finite element models of the assembled hollow core slab wall and the conventional hollow core slab wall with the proposed nodal connection method are constructed using the finite element software ABAQUS and numerical simulations are carried out. The feasibility and reliability of the nodal connection method are verified by comparing and analysing the hysteresis curve, ductility curve and stiffness degradation curve of the two. The results show that the proposed connection is an effective solution with good seismic and structural performance. These results provide a useful reference for the practical application of prefabricated hollow core slabs with vertical wall structures, and are expected to promote research and development in related fields.
