Evaluation of the effect of vertical component of earthquake acceleration on nonlinear time histories analysis of steel structures with irregularity in plan

With Honey To That At half Centuries Recent Attention To Build Structure S Steel Growing Have been Is And Also With pay attention to architecture new, some From Structure The Regular was not And At Named Structure S Irregular Put Is And With Attention To existence Fault S Near To Site Urban At country We ) Iran ( Need To analyze effects Come on From this Earthquake That way Structure The Feeling Out. At this Article review Effect Acceleration Right Earthquake On Structure S Referred to In a way Special review Has been . The irregular and irregular effects of 5- story steel structures have been modeled and evaluated . In the modeling of the software SAP The history analysis has been done on them . Also, Tabas Earthquake Accelerations, North Ridge and Chichi have been used in this research . These acceleration maps are entered into the software after scaling and applied to the structure in both directions . The results have shown that irregularly shaped models have a very functional cone shape amongst irregular models and behaved like a regular model . Also, in the irregular model of type 3 , due to the very torsion, we do not see proper performance and the values of drifts have increased dramatically . Also, the application of the vertical component of the earthquake has led to an increase in the axial force in the columns
