［摘要］天津大学仁爱学院图书馆建筑平面形状复杂，层1～2有局部不规则曲线形状的清水混凝土外墙，上部立面为清水混凝土带形窗。结构设计时，根据使用功能合理设置结构缝将整个建筑划分为4个结构单元。结合各单元特点，优化结构体系。针对清水混凝土外墙刚度对整体结构的不利影响，提出了弱化墙体刚度的措施，并对清水混凝土的设计、施工提出了相应的处理方案。

Abstract:The flat geometry of the library of Renai college in Tianjin university is very complex. There are some irregular curved fair-faced concrete outer walls at level 1 and 2, where the upper exterior is fair-faced concrete with narrow rectangular windows. According to the function of the structure, structural joints are reasonably distributed, which divide the whole structure into 4 structure units. The structure design of each unit is also optimized based its characterization. Because of the negative effect of the stiffness of the concrete outer walls on the stiffness of the whole structure, some methods to reduce the stiffness of the walls are proposed, as well as some suggestions on the design and construction of the fair-faced concrete.
Keywords:structure type; structural joint; stiffness reduction of the walls; fair-faced concrete
