摘　　要：为了给全现浇混凝土外墙的抗震性能研究提供有效研究手段,基于前期开展的全现浇混凝土外墙抗震性能试验,研究了这类结构的精细有限元模型的建模方法,建立了适用于整体结构分析的混凝土填充墙简化等效斜撑模型,提出了开窗洞填充墙斜撑位置和形式的确定方法,以及等效斜撑宽度和厚度的计算方法等。结果表明:采用所建立的精细有限元模型分析得到的全现浇混凝土外墙损伤模式以及滞回曲线、刚度和承载力特性等均与试验结果吻合良好,可以较好地反映试验试件的受力性能;简化分析模型计算结果与试验结果均较为接近;简化分析模型在有效提高了计算效率的同时,具有较高的准确性。所提精细和简化有限元模型可为全现浇混凝土外墙在构件层次和整体结构层次的有限元分析提供参考。To provide effective research methods for the seismic performance study of fully cast-in-place concrete exterior walls,a refined finite element modeling approach was studied based on previous seismic performance tests.Established a simplified equivalent bracing model for concrete infilled walls suitable for overall structural analysis,proposed methods for determining the location and configuration of diagonal bracing in infilled walls with openings,as well as for calculating the width and thickness of the equivalent diagonal bracing.The research results show that the damage pattern of the fully cast-in-place concrete exterior wall,as well as the hysteresis curve,stiffness,and bearing capacity characteristics derived from the refined finite element analysis,are in good agreement with the experimental results.Therefore,this model effectively reflects the mechanical performance of the test specimens.The results obtained from the simplified analysis model are also in close agreement with the experimental data.While it significantly enhances computational efficiency,the model still maintains high accuracy.The refined and simplified finite element models proposed in this study can serve as references for the finite element analysis of the fully cast-in-place concrete exterior walls at both the component level and the overall structure level.
