In this paper, static and dynamic characteristics of infilled wall structure were studied using the finite element analysis software MIDAS/Gen. The fundamental frequency of 0.9252 Hz was obtained by modal analysis. High-order modal participation factor was far less than the low-order modal participation factor, i.e., low-order modeplays a dominant role in the vibration. Time-history curve was selected based on two frequency bandsof the response spectra, and time-history analysis results were more than 80% of the response spectrum analysis results. The static and dynamic characteristicsof infilled wall structurewere obtained through response spectrum analysis and time-history analysis of this model, and the weak part of the structure was indicated, which may provide reference for the design and analysis of similar structures.
