Abstract: For different spans of column layout and different load effects, five different roof systems for underground garage were analyzed and the corresponding structural designing procedures were conducted. Then the economical efficiency and structural efficiency was studied, and the concept of generalized reinforcement ratio was proposed. 

Keywords: underground garage; roof system; structural efficiency; generalized reinforcement ratio
