［摘要］单纯采用钢筋网水泥砂浆面层加固砖墙，其抗震能力提高有限，为了进一步提高砖墙抗震性能，提出了采用增设钢筋混凝土-砌体组合构造柱与钢筋网水泥砂浆面层共同加固的加固方法。通过对9个加固试件进行了拟静力试验，分析了其破坏过程、破坏机理、滞回性能、延性及承载力等，结果表明：采用钢筋混凝土-砌体组合构造柱与钢筋网水泥砂浆面层共同加固的砖墙破坏形态主要表现为弯曲破坏，并且其延性、耗能特性和承载力均有显著提高；试件的高宽比、配筋率及轴压比对试件的延性、开裂刚度和承载力均有一定影响；可参照钢筋混凝土剪力墙计算其正截面承载力，计算时仅考虑组合构造柱内纵向钢筋作用，不考虑钢筋网竖向钢筋作用，且计算时受压区应考虑由不同材料组成，最后提出了钢筋混凝土-砌体组合构造柱与钢筋网水泥砂浆面层共同加固墙体的水平承载力计算公式。

 Abstract:The improvement of seismic performance of brick wall strengthened with steel-meshed cement mortar surface is limited. In order to further improve the seismic performance of the brick wall, the reinforcement method of using additional reinforced concrete-masonry combination structural columns and steel-meshed cement mortar surface was proposed.Based on the quasi-static test of 9 strengthened brick walls, the failure process, failure mechanism, hysteretic performance, ductility and bearing capacity were analyzed. The results show that the failure mode of brick wall jointly strengthened by reinforced concrete-masonry combination structural columns and steel-meshed cement mortar surface is bending failure, and its ductility, energy consumption characteristics and bearing capacity are significantly improved;the aspect ratio, reinforcement ratio and axial compression ratio of specimens have certain influence on the ductility, cracking stiffness and bearing capacity of specimens; the normal section bearing capacity can be calculated with reference to reinforced concrete shear wall, and only the longitudinal reinforcement action in the combination structural columns was considered in the calculation, and the vertical steel-meshed  was not considered, and the compression zone should be considered to be composed of different materials, the formula for calculating the horizontal bearing capacity of the wall jointly strengthened by reinforced concrete-masonry combination structural columns and steel-meshed cement mortar surface was derived in the end.

Keywords:masonry structure；  combination structural column； steel-meshed cement mortar surface； seismic reinforcement; quasi-static test; seismic performance
