Abstract:
Through the finite element analysis, studies on mechanical performance of prestressed steel-concrete composite beams when it is undered the low reversed cyclic loading, based on constitutive model of elastic-plastic and consider nonlinear property of materials, it indicated good agreement with the experiment. Change concrete strength of composite beams and study hysteresis curve, energy dissipation and so on.Study found that with the improvement of concrete strength, the hysteresis loop of prestressed steel-concrete composite beams become plump, down by the load carrying capacity, energy dissipation ability were improved significantly.when the load upward, the load bearing capacity,energy dissipation have a small rise, but not obvious. Incresae the concrete strength is good for dynamic performance of prestressed steel-concrete composite on the whole.
