（郑州市建筑设计院， 郑州 450000）[摘要]根据某砌体结构办公楼的现状及鉴定结论，采取外加圈梁-构造柱结合钢筋网砂浆面层的方法对其进行抗震加固和接建设计，并通过结构设计软件PKPM和规范评价方法对其进行了计算分析。结果表明，该方法既提高墙体的抗剪承载力，又增加了结构的整体延性，很好的改善了砌体结构的抗震性能。[关键词]砌体结构;加固设计;外加构造柱—圈梁;钢丝网水泥砂浆[中图分类号]TU746.3 文献标识码：A 文章编号：1002-848X（20130131）Seismic reinforcement and heightening design of a masonry structure building(Zhengzhou Architectural Design Indtitute, Zhengzhou 450052, China)[Abstract] According to the present situation and the seismic evaluation reports of the masonry structure building,carry out seismic reinforcement design and heightening design by the way of adding outside ring beam -structural column and the mortar surface layer of steel mesh, and analyze by PKPM software and the standard evaluation methods. The result shows that the method increased the anti-shear capacity and the structure overall ductility, improved the seismic performance.[Keywords] the masonry structure; reinforcement design;outside ring beam -structural column;the mortar surface layer of steel mesh
