Abstract:
Authors adopted finite element method(FEM)to study the bearing capacity of the studs of cold-formed thin-walled steel residence under vertical load. By the analysis for bearing capacity, failure mode and deformation of different studs unlined and those with plasterboards on one side and orient stand board on the other side, the accuracy of the FEM was validated. The influence of the parameters, including thickness of sheathings, studs spacing and screws spacing on the bearing capacity of studs was analyzed by FEM. The results show that when the thickness of sheathing is above 11 mm, the increase of thickness of sheathing can not enhance the axial bearing capacity of studs; when the studs spacing increase from 400 mm to 600 mm, the bearing capacity increases slightly; when the middle screws spacing is larger than 600 mm, the decrease of the screws spacing can increase the axial bearing capacity significantly; when the middle screws spacing is shorter than 600 mm, the increase of the axial bearing capacity since the decrease of screws spacing is not salient. The bearing capacity of the studs which was often used in cold-formed steel residential under vertical load, and the suggestion of design of the axial bearing capacity of such studs were presented.
