Critical Thinking on Design Methods for Reinforced Concrete Plate-Column Structures Used in Underground Garages
The purpose of this study is to interpret the code provisions,resolve differences,and integrate the code content when using reinforced concrete plate-column structures in underground garages.The critical thinking includes three aspects.First,the possibility of overloads is higher during the construction of underground garage compared to that of the superstructure.Therefore,the design procedure related to direct shear is recommended to include in the design method in the revised codes.Furthermore,four measurements were introduced to improve the punching resistance with respect to their characteristics and involved codes.Safety margin factors were also calculated when using the design expressions of punching.Finally,the conditions were expounded when using the top slabs of a basement as the embedded end for the superstructure.A typical case study was performed to demonstrate the rationality of the minimum"relevant range".In general,the critical thinking presented in this study is helpful for popularizing the use of reinforced concrete plate-column structures in underground garages.
