摘　　要：为了评估预应力钢-轻骨料混凝土组合梁的承载能力,根据不同的破坏状态,基于塑性理论推导了预应力钢-轻骨料混凝土组合梁的承载能力计算公式,并与试验结果进行了对比,误差在5%以内,对比结果表明该计算公式是合理的、可信的。为轻骨料混凝土组合梁在实际工程中的推广和使用提供了充分的理论基础。In order to evaluate the limit flexural capacity of prestressed lightweight aggregate composite steel-concrete beams,The limit flexural capacity formula was derived based on plastic theory according to different damage states.At the same time the results were contrasted with experimental ones,and the error is less than 5%,validating this formula is reasonable and believable.This method offers sufficient theoretical basis for spread and application of lightweight aggregate concrete composite beam.
