Influence of axial compression ratio to RC frame structure under different span different layers

Hong Gan

Abstract

Based on seismic method of calculating the weak layers of reinforced concrete frame structure,the weak layer is determined and comparative analysis is carried out.The influence of the axial compressive ratio of frame column frame structure damage pattern and ductility are analysed.The current seismic code's limit value of the axial compressive ratio is high which mainly leads to frame structure failure.By adjusting the change of frame column section size and controling the large eccentric loading range of destruction,the aseismic capacity of building can be improved.
