摘　　要：为明确波折钢板-内衬混凝土组合梁组合结构中内衬混凝土的作用,及其对组合结构的极限承载能力、变形能力以及稳定性能的影响,通过推导波折钢板内衬混凝土组合构件的等效刚度及强度计算模型,对其剪切性能进行研究;通过研究波折钢板-内衬混凝土组合受力机理,明确两者之间的刚度分配原则以及受力承担比例。研究结果表明:由于波折钢板与混凝土两者共同承担弯矩与剪力,组合结构的强度与刚度得到提高。In order to clarify the role of lined concrete in the composite structure of corrugated steel plate-lined concrete composite beams,and its impact on the ultimate bearing capacity,deformation capacity,and stability performance of the composite structure,the equivalent stiffness and strength calculation model of corrugated steel plate-lined concrete composite components are derived to study their shear performance;by studying the stress mechanism of the combination of corrugated steel plate-lined concrete,the stiffness distribution principle and force bearing ratio between the two are clarified.The research results show that:the strength and stiffness of the composite structure are improved due to the joint bearing of bending moment and shear force by the corrugated steel plate and concrete.
