摘要:
为了研究波形钢腹板内衬混凝土部位的抗剪性能,基于室内模型试验,开展了内衬混凝土的直钢板和波形钢板抗剪试验,同时采用不设内衬混凝土的直钢板和波形钢板模型进行对比试验研究.提出了波形钢板内衬混凝土部位的拉-压杆抗剪强度计算模型,给出了压杆宽度影响系数值为0.188.试验结果表明,内衬混凝土受压杆与波形钢腹板受拉杆形成X桁架,共同提供抗剪承载能力.设置内衬混凝土的波形钢板抗剪强度比对应的直钢板大.在波形钢腹板箱梁正常使用阶段的应力验算时,可直接采用波形钢腹板和内衬混凝土的刚度比值进行验算.
Abstract:
To study the shear behavior of the corrugated steel plate encased with concrete, model tests of straight steel plate and corrugated steel plate encased with concrete were carried out. Menwhile straight steel plate and corrugated steel plate model tests without encased concrete were made, and compared with those of the encased concrete models. The shear strength model for the compression and tension struts of the corrugated steel plate encased with concrete was presented, and the width coefficient of compression strut was 0.188.Test results show that the encased concrete compression strut and the corrugated steel tension strut form X truss to provide the shear bearing capacity. The shear capacity of the corrugated steel plate encased with concrete is larger than that of straight steel plate encased with concrete. The shear distribution ratio of the encased concrete and the corrugated steel plate can be used to analyze stresses of the box girder with the corrugated steel plate at service limit state.
