Abstract:对12根衬塑钢管海水海砂混凝土(seawater sea-sand concrete filled plastic-lined steel tube,SSC-PLST)试件进行了受弯加载试验和有限元建模分析,研究该类构件的受弯性能及内衬塑料层对组合构件承载变形能力的影响规律。研究结果表明:SSC-PLST受弯构件的破坏形态具体表现为受压区钢管外凸屈曲、对应位置混凝土被压碎,受拉区钢管屈服、核心混凝土弯曲裂缝细而密,与普通钢管混凝土类似;试件的弯矩-挠度曲线呈三阶段特征,表现出良好的承载与变形性能。SSC-PLST构件不同部分之间的接触应力较小,且分布不均匀。内衬塑料对SSC-PLST构件受弯承载力的影响程度主要与塑料层厚度有关,受钢材强度和混凝土强度的影响较小。最终提出了SSC-PLST 受弯构件承载力的简化计算公式,可为该结构构件的工程应用提供参考。
