摘要

通过4块足尺试件的四点弯曲试验，研究中等跨度玻璃纤维增强复合材料（GFRP）网格增强水泥基植物纤维增强复合材料（PFRCC）预制装配式单向叠合板在正、负弯矩作用下的受力性能，分析保护层厚度对其破坏模式、裂缝分布、应变发展、承载力及延性的影响。结果表明：正弯矩试件破坏前无明显变形，GFRP网格断裂后荷载出现陡降；负弯矩试件破坏过程平缓，类似于适筋梁，最终两者均发生受压区压溃。相较于小跨度板，中等跨度叠合板展现出更大的挠度和更突出的几何非线性效应。该叠合板兼具轻质和良好延性，正弯矩试件极限承载力较负弯矩试件和等截面现浇板分别提高约50%和23%，而负弯矩试件因GFRP网格桥联优势未能发挥及PFRCC抗压强度较低，承载力较现浇板降低约17%。此外，预制板置于受拉区可显著抑制裂缝扩展，正弯矩试件裂缝间距较负弯矩试件缩小20%~30%。最后，基于试验结果，对规范中开裂弯矩公式中的截面抵抗矩塑性影响系数基本值进行修正。

Abstract

Through four-point bending tests on four full-scale specimens

this study investigates the mechanical behavior of medium-span glass fiber reinforced plastic (GFRP) grid-reinforced plant fiber reinforced cementitious composites (PFRCC) prefabricated monolithic one-way composite slabs under positive and negative bending moments. The influence of concrete cover thickness on failure modes

crack distribution

strain development

load-bearing capacity

and ductility was analyzed. The results indicate that prior to the failure of the positive-moment specimens

there is no obvious deformation

and the load drops sharply after the fracture of the GFRP grid. The failure process of the negative-moment specimens is gentle

similar to that of a moderately-reinforced beam

and ultimately

crushing occurs in the compression zone of both types of specimens. Compared with the small-span slabs

the medium-span composite slabs exhibit greater deflection and more prominent geometric nonlinear effects. This composite slab combines the advantages of light weight and good ductility. The ultimate bearing capacity of the positive-moment specimens is approximately 50% and 23% higher than that of the negative-moment specimens and the cast-in-place slabs with the same cross-section respectively. However

due to the unfulfilled bridging advantage of the GFRP grid and the relatively low compressive strength of PFRCC

the bearing capacity of the negative-moment specimens is about 17% lower than that of the cast-in-place slabs. In addition

placing the precast slab in the tension zone can significantly inhibit the crack propagation

and the crack spacing of the positive-moment specimens is 20%-30% smaller than that of the negative-moment specimens. Finally

based on the test results

the basic value of the plastic influence coefficient of the section resistance moment in the cracking moment formula in the code is corrected

providing a reference for the design of similar components.
