Anti-progressive-collapse method suitable for steel-concrete composite structure
The invention provides an anti-progressive-collapse method suitable for a steel-concrete composite structure. The method comprises the steps that 1, anchor cables, anchorage devices and fixing parts are prepared; 2, through holes are formed in the two sides of the joint of a steel pipe concrete column and a steel beam and used for allowing the anchor cables to penetrate through; 3, the two sides of a web of the I-shaped steel beam are each provided with one anchor cable, and the anchor cables are fixed to the two sides of the web through the fixing parts; 4, the anchorage devices are used for locking and fixing the anchor cables to prevent slipping; 5, the fixing parts are welded between an upper flange of the steel beam and the web and used for limiting lateral movement of the anchor cables; and 6, the anchor cables are in a loose and non-stressed state at ordinary times, the anchor cables are stressed and clamped only when the middle column fails and enters the large-deformation catenary stage, and the structure is prevented from progressive collapse. When the middle column fails and enters the large-deformation catenary stage, the anchor cables and side columns form an effective pulling structure, and the structure is prevented from progressive collapse.
一种适用于钢‑混凝土组合结构抗连续倒塌方法，步骤1，备好锚索、锚具和固定件；步骤2，在钢管混凝土柱与钢梁连接两侧处开设有贯穿孔，用于穿过锚索；步骤3，工字型钢梁腹板两侧分别布设一根锚索，采用固定件固定锚索于腹板两侧；步骤4，采用锚具用于锁紧固定锚索，防止滑脱；步骤5，采用固定件焊接于钢梁上翼缘与腹板之间，用于限制锚索的侧向移动；步骤6，所述锚索在平时为松弛不受力状态，当中柱失效进入大变形的悬链线阶段才会受力卡紧，防止结构出现连续性倒塌。在中柱失效进入大变形的悬链线阶段，锚索和边柱形成有效的拉结结构，防止结构出现连续性倒塌。
