钢结构复式剪力筒钢结构复式剪力筒，主要采用粗钢筋以螺旋形式交叉编结，使其成为网状筒壁，沿交叉点纵向焊接直筋以增强筒壁的强度，然后将腹杆分别焊接、扎结在筒壁的各交叉点上，形成纵向排列的“米”字形结构的筒芯。经过大量的测试，其强度、刚度、局部稳定、整体稳... Steel composite shearing tube steel composite shearing tube is mainly made of coarse steel bars and is cross-knotted in a spiral manner to make it into a mesh tube wall. Straight reinforcements are welded longitudinally along intersections to increase the strength of the tube wall, and then the web rods are separated. Welded and tied at each intersection of the wall of the tube to form a vertically arranged “rice” shaped core. After a large number of tests, its strength, stiffness, local stability, overall stability...
