摘　　要：从砌体填充墙建模方式、框架与填充墙接触关系模拟方法和数值分析方法的选择3个方面对填充墙框架结构水平受力性能数值模拟方法进行剖析,并以上海外滩早期历史建筑钢框架低周反复加载试验研究为基础,对整体式和分离式2种有限元建模方法进行对比分析,发现考虑墙-框界面接触关系、将砌体作为均质连续材料的整体式有限元模型能够较好地反映填充墙钢框架结构整体荷载-位移关系、刚度退化现象及应力分布,而将填充墙按砖块和砂浆建模的分离式模型则能够较好地反映填充墙破坏形态,但分离式建模复杂、计算耗时,相较之下整体式模型更适用于填充墙框架结构整体受力性能的数值模拟.The state-of-art of numerical simulation of masonry-infilled frames is given through a review of selection of modeling of masonry infilling walls, modeling of contact between frames and infilling wails, and numerical algorithm. Based on the previous experimental study of historical masonry-thrilled steel frames in Shanghai, homogenized model and discrete model are compared. It is found that homogenized model can effectively simulate structural performance of infilled frames including load-displacement curves, rigidity degradation, and stress distribution. But discrete model can estimate the crack pattern of infilling wails with much more processing time.
