Experimental Study of the Collapse Performance of RC Frame under Hammer Load
摘要
Abstract
Two 2-bay,1-story RC plane frames were tested to study the static and dynamic behavior of RC frame structure after the column's failure.A static experiment was done to obtain the static behavior data of frame structure,and based on another test frame,hammer experiments were used to obtain the frame beam's dynamic response data of displacement,acceleration and steel strain under no load and uni-formly distributed load,respectively.The mechanic behavior of the frame beam under hammer load was studied by comparing the static and dynamic test results.The tests results were as follows:there was a linear relationship between the dynamic displacement amplitude and the input impulse under hammer load;with the increase of the hammer load,the damping of the structure changed little while the frequency de-creased;the frame beam with uniformly distributed load formed the arch effect under hammer load,so its stiffness increased slightly;the maximum hammer load exceeded the frame beam's maximum resistance force,but the frame beam did not collapse because of the small impact energy.关键词
