Seismic Analysis Of The Less Wall Frame Structure System Of Primary And Middle School Teaching Buildings In High Intensity Area

Taking a 6-story primary and secondary school building model as an example,this paper uses SAP2000 software to analyze the elastoplastic time history of frame structure and less wall frame structure under the action of multiple earthquakes and rare earthquakes,and study the shear wall at different positions.The impact on the seismic performance of the structure.It is found that the period ratio of the central wall system is the largest,and the interlayer displacement angle of the small shear wall structure system under the multiple earthquakes is much smaller than that of the pure frame structure;in the rare earthquake,the middle wall corner system is less It can effectively reduce the structural torsion effect;the appearance of the plastic hinge of the small wall frame structure system is mainly due to the connection between the shear wall and the frame coupling beam,so it is necessary to pay attention to coordinate this part of the reinforcement.By analyzing the sensitivity of the wall limb parameters,it is found that with the increase of the wall and limbs,the indexes of the wall frame system are effectively controlled.The results of the research show that the frame structure system with the middle corner is more resistant to the frame structure.The effect is better,and it provides a reference for the selection of teaching buildings in primary and secondary schools in the future.
