Abstract

The web light-gauge steel system is a new type of steel structure, which has a good application prospect. However, in practical application, the problem of large opening in the wall often leads to a large opening ratio in structure, which has a negative impact on the structural safety. In this paper, according to the characteristics of the light-gauge steel structure, using ABAQUS finite element software and reasonable simplified modeling method, the validity of the model is verified by modal analysis, and the natural vibration period and modal calculation results of the structure are obtained, and the calculation results are consistent with those in the literature. The modal analysis and time history analysis of the structural model with different opening ratios show that: with the increase of opening ratio, the natural vibration period of the structure is approximately 1:1 linear growth, and the displacement growth is slow first and then fast, shows a critical change point. Based on the analysis results, reasonable design suggestions for different seismic fortification intensity regions are put forward.
