abstract

Based on the theory of elasticity mechanics and fracture mechanics, the cracked concrete beam with the effect of reinforced constraints is modelled and analyzed by the energy angle, and the governing equation is established using Reissner variation principle. Then in numerical calculation, the effects of geometry nonlinear, structural damping, crack parameters, as well as the reinforced constraints on dynamic response of beam under the rectangular pulse load is investigated. The motion laws of cracked beam are discussed and summarized.
