Safety Analysis of the Steel Frame in Stereoscopic Garage under the Wind Load

Abstract

In order to study the safety performance of the stereoscopic garage steel frame under wind load, the numerical model of the stereoscopic garage steel frame was established by using the finite element analysis software ANSYS. Calculate and safety analyze the steel frame of the garage in three conditions which are the full-load state without the wind load, full-load state with the wind load and empty in the middle car layer but full load of top with the wind load,. The results show that the deformation and the stress of the steel frame existing in most stereoscopic garages meet the safety criterion without the wind load. But when the wind load is considered, the deformation and the stress of the steel frame under full load is larger than the safe displacement and the safety stress which is allowable when the wind load is considered. The steel frame is not safe. It is necessary to increase the column size or improve the material of the steel frame in the stereoscopic garage according to the deformation and stress analysis. In the design or the safety assessment of the steel frame of stereoscopic garage, the role of wind load must be considered.
