摘　　要：应用线弹性及初应力增量有限元法分析砌体填充墙参与协同工作的框架结构体系,由于填充砌体的抗拉、压抗力的显著差异,填充墙的抗力作用不能得以充分发挥,填充墙砌体部份首先屈服破坏。若采用配筋砌体或在砌体内加构造柱及卧梁等技术措施,能较有效地提高结构的强度、刚度、改善动力学特性,对挖掘结构的承载能力,作用是显著的。The cooperation of the frame structure system and the wall filled with masonry is analyzed by the finite element method of linear elasticity and first stress addition. A part of the wall filled with masonry is yielded to crack at first because of the great difference of the tensile stress and the compressive stress of it. The strength,the stiffness,and the dynamic character of the structural will be effectively improved if these technologic methods such as reinforced masonry,placing structural concrete columns and beams in the masonry and so on are used,which is valid to dig the bearing capacity of the structure.
