ABSTRACT:

The configuration of a kind of multi-storey or high-rise steel three-dimensional parking structure is introduced in this paper. The approximate analytical method is studied in detail. The whole structure is regarded as a vertical cantilever. The equivalent bending stiffness and shear stiffness of the structure, including the shear stiffness of the lateral bracing system and that of the beam-column system, are derived. The lateral displacement formula of the structure under horizontal load is subsequently developed. Then the calculation formulae of internal forces of various structural components are derived. Numerical example shows that the error of the results by the presented formulas does not exceed 7.2% in comparison with those by finite element method. Therefore, the method and its related formulae are feasible for preliminary design of this kind of steel three-dimensional parking structure since it is accurate and brief.
