Dynamic analysis of reinforced concrete beam under shock wave Yang Liu1,a, Derong Wang1,b and Cuncheng Shi2,c 1Engineering Institute of Engineering Corps, PLA University of Science and Technology, Nanjing, Jiangsu 210007, China 2The Fifth Department, the Second Artillery Command College, Wuhan, 430012, China ananjb821045@163.com, bwdrjb@163.com, cshicuncheng@126.com Key words: reinforced concrete beam; shock wave; dynamic response Abstract: Bearing capacity of RC beam calculated by using typical dynamic computing methods can not define the truly distributed internal force all over the deflection from the beginning of load; the main reason is the change of the form of deflection and internal force to time are not taken into account.
Introduction The study of dynamic response and mechanism research of beams subjected to moving loads is one of the frontier projects in mechanical, industrial and civil engineering.
