摘要

研制了一种具有预应力钢筋的钢-混凝土-钢夹层板，称为预应力钢-混凝土夹层板。在荷载模式、顶部钢板厚度、连接件间距和预应力钢筋布置不同的情况下，对9个试件进行了试验测试，以探讨结构的破坏模式、极限强度、延性和挠度。结果表明，预应力提高了结构的极限强度和延性。有限元分析预测与试验结果在裂缝特征、荷载-位移曲线和极限强度方面一致。基于变分理论对预应力板的挠度进行了预测分析，与有限元结果吻合较好。

Deflection assessment of prestressed steel-concrete–steel sandwich panel: experiment and numerical simulation

A steel-concrete-steel sandwich panel with prestressed reinforcement was developed, named prestressed steel-concrete–steel sandwich panel. Nine specimens where the loading mode, top steel plate thickness, spacing of connectors and prestressed reinforcement arrangement were varied were experimentally tested to explore the failure mode, ultimate strength, ductility and deflection of the structure. The results show that prestressing enhanced the ultimate strength and ductility of the structure. Finite element analysis predictions were consistent with test results in terms of crack characteristics, load-displacement curve and ultimate strength. Deflection prediction analysis of the prestressed panels was also developed based on variational theory which provided good agreement with the finite element results.
