RESPONSE ANALYSIS OF DYNAMIC RESPONSES OF SIMPLY SUPPORTED BEAMS WITH UNIFORM HARMONIC LOADS

Lei Liang

Abstract

For railway bridges,the load effect of irregularity lane and wheel weight imbalances is a moving harmonic force.The dynamic responses of simply supported beams with uniform moving loads are studied based on the kinematics equations and by taking the mass and speed of the moving object and the high order natural frequencies of the beam into consideration.
