摘　　要：为充分发挥波纹钢混凝土组合板力学性能,本文提出预应力波纹钢混凝土组合板结构。在利用试验结果验证数值模型准确性的基础上,对不同类型组合板进行了力学性能比较分析,研究了结构受荷历程和破坏模式,明确了上波纹钢板和预应力的作用机制,二者组合后显著提高了组合板弹性工作范围和抵抗破坏能力。进一步通过参数化分析,研究了预应力双层波纹钢混凝土(PSCS)组合板力学性能变化规律,结果表明:波纹钢板型号、核心混凝土厚度、栓钉间距及预应力水平对PSCS组合板抗滑移能力和抗破坏能力影响重大,其中核心混凝土厚度和波纹钢板波形影响更为明显,恰当的预应力水平能够更好发挥PSCS组合板力学特性。研究结果可为预应力波纹钢混凝土组合板结构的设计和优化提供参考和指导。To fully exploit the mechanical performance of corrugated steel-concrete composite plate,this paper proposes a prestressed corrugated steel-concrete composite plate structure.Based on the validation of the accuracy of numerical models using experimental results,different types of composite plate were analyzed and compared for their mechanical performance.The loading process and failure mode of the structure were studied to clarify the mechanism of the upper corrugated steel plate and prestressing in the composite plate,in which the combination of the two significantly improved the elastic working range and failure resistance of the composite plates.Additionally,the mechanical properties of prestressed double-layer corrugated steel-concrete(PSCS)composite plates are studied.The results show that:the type of corrugated steel plate,the thickness of core concrete,the spacing of studs and the prestress level have a significant influence on the anti-sliding ability and anti-damage ability of PSCS composite plates,among which the thickness of core concrete and the waveform of corrugated steel plate have a more obvious influence.Appropriate prestress level can better exert the mechanical characteristics of PSCS composite plates.The results of this study provide useful reference and guidance for the design and optimization of prestressed corrugated steel-concrete composite structures.
