Seismic performance of multi-story modular box buildings
Abstract In view of the increasing application of mid-rise modular box buildings, theoretical and numerical research of multi-story modular box buildings are necessary. The research presented in this article investigated the seismic behavior of the multi-story modular box buildings using numerical simulation. Modal analysis and analysis of buildings under frequent and rare earthquakes were conducted. To fulfill the building model, a simplified model of single container was established using the equivalent spring model and shear behavior of a single container was studied. In addition, the stiffness and capacity of four kinds of joints using in the building were calculated. The results show that the multi-story modular box buildings with the current joints do not satisfy the Chinese code, and new connections and structural systems are required for further application.
Highlights The shear bearing capacity and stiffness of the cross-shaped clamping joint are capable in multi-story modular box buildings. The accuracy of the simplified model using equivalent spring model is acceptable. It is difficult for multi-story modular box buildings using the existing assembly joints to meet the requirements of the specifications.
