玻璃纤维增强聚合物混凝土小型空心砌块复合墙片的抗震性能
Anti-seismic behavior of composite GFRP-concrete small hollow block wall
【摘要】 针对混凝土小型空心砌块墙体抗震性能较差的问题,提出了将具有良好力学性能的玻璃纤维增强聚合物(GFRP)片材粘贴在混凝土小型空心砌块墙体表面形成GFRP-混凝土小型空心砌块复合墙体来改善原混凝土小型空心砌块墙体的抗震性能的设想。通过5个试件(含一个对比用的标准试件)的伪静力试验,研究了采用不同纤维片材粘贴方式得到的复合墙片的抗震性能。试验结果表明,复合墙片比原墙片具有更高的受剪承载力、延性和耗能能力。
【Abstract】 In consideration of the unsatisfactory anti-seismic behavior of the concrete small hollow block wall,an idea to improve the behavior was proposed,that is,sticking the glass fiber reinforced polymer(GFRP) sheet with good mechanical properties on the surface of the concrete wall to form a composite GFRP-concrete small hollow block wall.Through the quasi-static tests on 5 specimens including 1 standard specimen for contrast,the anti-seismic behaviors of the composite GFRP-concrete small hollow block walls with different GFRP sheet sticking modes were investigated.The test results indicate that the anti-seismic behavior of the composite wall is better than the concrete wall,the composite wall is characterized by higher shear bearing capacity,ductility and energy-dissipation capacity than the concrete wall.
