Abstract:
In order to study the disadvantageous influence of torsional effect of cold-formed thin-walled steel structure, whose deflections among the structural stiffness center, mass center and geometry center existed, the structural total displacements were divided into parallel displacement and rotational displacement, and the parallel shear and the rotational shear of composite walls were accordingly obtained, then the effect would be superposed. Finally, the calculation formulae of the structural linear-elasticity storey torsion angle, shear force and lateral displacement of composite walls were derived. The storey torsional effect of cold-formed thin-walled steel residence structure under horizontal load was calculated by the simplified formula, and the numerical result was analyzed by ANSYS finite element program. Results show that the calculated results using two methods are close to each other, and the structure response by torsional effect under horizontal load is distinct. The simplified formula can be used as reference on calculation of torsional effect of cold-formed thin-walled steel residence structure in engineering.
