Dynamic tests and numerical simulation of reinforced concrete beams
【Abstract】 The effects of loading rate that might be experienced during earthquakes on reinforced concrete beams were experimentally and numerically studied here. Firstly,the effects of loading rate on mechanical properties and deformation of reinforced concrete beams were experimentally studied with the variation of several parameters including concrete strength,steel strength,shear span ratio,loading rate and loading mode. Then,based on the finite element software ABAQUS,considering the strain rate sensitivity of concrete and steel,the dynamic performances of reinforced concrete beams under different loading conditions were simulated,and the simulation results agreed well with the test ones.
