摘　　要：玻璃砌体拱是一种以玻璃为主要构成材料的砌体拱结构,具有独特的透明度和光线穿透性。文章采用FDEM模拟了铝硅酸盐玻璃试样在三点弯曲试验中的断裂,以及玻璃砌体拱在竖向荷载下的变形。通过验证FDEM模拟玻璃砌体拱受力性能的可靠性,进一步对4组由不同夹层和玻璃砌块组合成的玻璃砌体拱开展了参数化研究,以评估玻璃砌体拱的受力性能。研究表明,夹层能改善玻璃砌体拱的变形能力和阻止接触砌块间裂缝的扩散,而砌块中互锁形状的存在抵抗了接触面之间的相对滑移趋势。Glass masonry arch is a kind of masonry arch structure with glass as the main composition material,which has unique transparency and light penetration.In this paper,FDEM is used to simulate the fracture of silicate glass samples in a three-point bending experiment and the deformation of glass masonry arch under vertical load.By verifying the reliability of FDEM on the mechanical performance of a glass masonry arch,a parametric study was carried out on four groups of glass masonry arches composed of a different interlayers and glass blocks to evaluate the mechanical performance of the glass masonry arch.The results show that the interlayer can improve the deformation ability of glass masonry arch and prevent the development of cracks between the contact blocks,and the interlocking shape of the block can resist the relative slip trend between the contact surfaces.
