Single-story and single-span portal frame structure seismic performance time history analysis

In order to explore light portal frame structure of the effects on seismic characteristics.This paper use of finite element software ANSYS analysis"Atlas of Gate-type Rigid-framed Light House Steel-frame Standard"(02SG518-1)[1] in single-story and single-span portal frame on the horizontal seismic action calculation.This paper analyzes the structure under different seismic wave and different seismic fortification intensity phase of the mechanical properties,deformation characteristics and failure mechanism.Final analysis results show that the standard atla(02SG518-1) frame design accord with"Construction Anti-seimsic Design Standard"(GB50011-2010)[2]"small earthquake not bad,the shock of repairable,not strong"of the requirements for seismicresistance.That single-story and single-span portal frame structure has good seismic performance.
