Abstract

To study the damping effect and the feasibility of the lead damper for the cold formed steel structure with self-tapping screws, the experimental results are analyzed based on the monolithic wall low cycle loading test. The finite element model establishment method for accurately represent the wall hysteretic performance of cold-formed thin-walled steel wall and the overall structure is established. The time-varying damage index based on stiffness or elastic-plastic energy difference, and the time-varying ductility coefficient are used to analyze the damage evolution characteristics of the whole structure of cold-formed thin-walled steel. The dynamic time-history analysis and damage analysis of the whole structure of cold-formed thin-walled steel are carried out. A typical cold-formed thin-walled steel office building structure is established and dynamic time-history analysis was carried out to study the damping effect of the overall structure of cold-formed thin-walled steel under different seismic amplitudes. The results show that the lead damper can not only significantly improve the mechanical and seismic performance of the shear wall, but also significantly reduce the dynamic response and damage degree of the whole structure of the cold-formed thin-walled steel under large earthquakes. The whole system has good damping performance and application prospect.
