EXPERIMENTAL STUDY ON IMPACT RESISTANCE OF FRAME COLUMNS IN PREFABRICATED BUILDING
In order to study the stress and deformation evolution process of frame columns of prefabricated building after being subjected to impact load,comparative tests on impact resistance of cast-in-place frame columns and prefabricated frame columns were conducted.The results show that as the impact speed increases,the peak value of the impact force also increases,and the duration of the impact force correspondingly decreases.An increase in the assembled axial compression ratio will significantly increase the impact force,while the duration of the impact force will correspondingly decrease.As the impact speed increases,the maximum strain of the steel bars in prefabricated frame columns continuously increases,and the increase in axial compression ratio has little effect on the maximum strain of the steel bars.
