摘要:
为研究GFRP-混凝土组合板的受力性能,对3块GFRP-混凝土组合连续板进行了静载试验.3块组合板分别通过环氧树脂胶或剪力栓钉与下部型钢支座连接.试验结果表明:所有组合板的最终破坏形态均表现为加载垫块处局部冲剪破坏;中支座处和边支座处没有出现荷载重分布现象,组合板表现出良好的空间受力性能及变形协调能力.然后,基于塑性极限理论,提出了一种GFRP-混凝土组合板极限承载力计算方法.预测值与试验值的比较结果表明,所提方法可以有效地预测GFRP-混凝土组合板的极限承载力.
Abstract:
In order to investigate the mechanical behavior of GFRP(glass fiber reinforced polymer)-concrete composite slabs, three continuous GFRP-concrete composite slabs were tested under the static loads. The three composite slabs were connected with steel girder supports by either epoxy resin or shear studs. The experimental results show that all specimens are damaged with local punching shear failure at the loading pads. The load redistribution is not observed in middle and end supports. The composite slabs exhibit good mechanical performance and deformation compatibility. Then, based on the plastic limit theory, a calculation method for the ultimate load capacity of the GFRP-concrete composite slab was proposed. By comparing the test results with the predicted values, the effectiveness of the proposed method on predicting the ultimate load capacity of GFRP-concrete composite slabs is verified.
