Seismic Performance of Assembled Building Structure in Smart City

Abstract

Abstract In recent years, prefabricated buildings have made good development. Compared with ordinary reinforced concrete construction projects, prefabricated buildings have higher requirements for seismic resistance. In this paper, the seismic performance of the assembled building structure in smart city is studied. In the study, we use open sees to establish the finite element model, and take the common seismic performance indexes as the evaluation indexes, and compare the prefabricated structure with the cast-in-place structure from the aspects of ductility, stiffness degradation and energy dissipation. The results show that when the displacement reaches 80 mm, the energy consumption of the two structures reaches the maximum value, and the energy consumption of prefabricated structure is 20000 KN / mm, and that of cast-in-place structure is 30000 KN / mm. In addition, the research results show that the ductility coefficient of prefabricated structure is slightly smaller than that of cast-in-place structure, but its stiffness degradation is better than that of cast-in-place structure. Generally speaking, the seismic performance of prefabricated building structure is better than that of cast-in-place structure. The research results of this paper will provide certain reference value for the development and construction of smart city.
