Abstract

A nonlinear dynamic numerical simulation on seismic behavior of a two-story cold-formed steel framing building full-scale shaking table test model was carried out by the way of from components to integral structure. Firstly, refined numerical model of shear wall was established, and restoring force models of screw connections between the framing and sheathings were integrated into the numerical model of shear wall. The refined numerical model of shear wall was verified by tests. Secondly, based on refined numerical model of shear wall and modified exponential “Foschi” skeleton curve, uniform restoring force skeleton curves of two typical shear walls of the shaking table test model were obtained. Then, a simplified numerical model of shear wall was proposed. Finally, a dynamic numerical model of cold-formed steel framing building was established based on the simplified shear wall model and assumption of rigid diaphragm, and nonlinear dynamic analysis was carried out. The results of numerical simulation agreed well with the tests, which indicated that the numerical model of integral buildings can factually reflect the dynamic behavior of cold-formed steel framing building.

Numerical Simulation on Dynamic Behavior of a Cold-Formed Steel Framing Building Test Model

A nonlinear dynamic numerical simulation on seismic behavior of a two-story cold-formed steel framing building full-scale shaking table test model was carried out by the way of from components to integral structure.
