摘要
进行了5片3D打印配筋砌体墙和3片普通砌块配筋砌体墙的轴压、偏压试验,分析了3D打印配筋砌体墙在不同偏心荷载作用下的破坏特征,并与普通砌块配筋砌体墙进行对比;研究了3D打印配筋砌体墙的受力与变形性能、破坏过程与破坏形态,为3D打印配筋砌体墙替代普通砌块配筋砌体墙的可行性提供理论计算基础和设计依据.结果表明:3D打印配筋砌体墙整体性较好,承载力较高,可达到同等受力条件下普通砌块配筋砌体墙的2倍左右.
Five 3D printing reinforced masonry walls and three common block reinforced masonry walls were tested under central and eccentric loading. The failure mode, deformation, and bearing capacity of 3D printing reinforced masonry walls and common block reinforced masonry walls were compared and analyzed, providing theoretical and design basis for the feasibility on 3D printing reinforced masonry wall. Experimental results indicate that compared with common block reinforced masonry walls, the integrity of 3D printing reinforced masonry wall is better, the bearing capacity of 3D printing reinforced masonry wall is 2 times that of common block reinforced masonry wall under compression.
