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
