摘　　要：本义对大开间砖砌体结构在大开间两侧横墙采取在砖砌体中增设钢筋混凝土墙中柱和水平条带的加强措施。在大比例模型试验的基础上,对约束砌体横墙进行静力非线性分析,论证了采取此项加强措施后可满足相应的抗震设防要求,捉出一种改进的约束砖砌体横墙极限承载力计算方法。The load-bearing capacity of confined brickmasonry walls in a multistory building with a large-bay is researched, some reinforced concrete columns and strips have been added in the confined brickmasonry walls to enhance their seismic brhavior. Static nonlinear anaysis of the transverse confined brickmasonry walls has been achieved, the computed results show that the load -bearing capacity of the confined brickmasonry walls after strengthening measures can meet reguirements of seismic design. Based on the test data and computed results, a modified formula to calculate the ultimate bearing capacity of the confined brickmasonry wall is proposed.
