摘　　要：总结砌体结构改造的发展情况,介绍砌体结构改造中托梁的多种设计方法以及一些工程应用,重点提出了钢板-砌体组合结构加固改造砌体结构的新方法。针对这一新方法,进行了钢板-砌体组合结构的梁受弯性能、柱轴心受压和偏心受压性能试验研究。试验结果表明:钢板厚度越厚,螺栓间距越小,灌注材料的粘结性能越好,钢板-砌体组合梁柱极限承载力越高。This paper summarizes the development of masonry structural transformation.It introduces the methods of masonry structural transformation and their engineering applications and highlights the newly-developed steel plate-masonry composite structures.Experiments are conducted to steel plate-masonry composite beams under bending moments and steel plate-masonry composite columns under axial and eccentric compressions.The following conclusions can be drawn: mechanical properties of steel plate-masonry composite beams and columns are seriously influenced by the space between bolts,structural adhesive quality and steel plate thickness.Thicker steel plate offers higher ultimate strength of steel plate-masonry composite beams and columns.Smaller space between bolts offers higher ultimate strength;Better adhesive property of infusion materials offers higher ultimate strength.
