A Prefabricated Underground Cylindrical Garage and a Corresponding Stiffness Analysis
This paper presents a design of a prefabricated structure for an underground cylindrical garage. The performance of this structure and the node connections in terms of lateral stiffness is investigated, which is critical to the safety of the excavation process. Analytical solutions of the lateral stiffness of the prefabricated structure are derived considering compatible displacement. A 3D model of the prefabricated structure is developed and used in the numerical simulation to verify the theoretical model. As the key factor of the lateral stiffness of the prefabricated structure, the lateral stiffness of the node is also obtained via laboratory testing. Three connection nodes are fabricated according to the design and are tested in the laboratory. The influence of the cross-sectional area of the connection beam and the thickness of the column base on the lateral stiffness of the connection node is also investigated in the laboratory test.
