摘　　要：某住宅楼原设计为上部5层砖混、下部1层框架剪力墙的6层混合结构,经现场检测,实际施工为8层,底框梁截面小于原设计值,其桩基混凝土强度推定值为16.9MPa,达不到原设计C30混凝土的强度等级。本文通过现场检测、承载力计算将原结构体系改为多层砌体结构房屋,并进行相关构件的加固处理,可供类似工程参考。The original structure of the residential building was designed for the bottom of the frame shear wall structure housing.The actual construction is 8 layers instead of 6 layers of the original design,bottom beam section is less than the original design value,the pile of concrete strength of the presumption is 16.9MPa,less than the design of the C30 concrete strength.Through texting and analysising,the original structure is changed into multi-storey masonry structure,and reinforcement is carried out.It could give recommendations for similar projects.
