摘要

摘要: 为研究冷弯薄壁构件应用于高大工业厂房吊架系统的可行性，提出了一种双肢冷弯C型钢吊架系统。考虑不同的吊架梁跨度、荷载设计值和C型钢腹板间连接缀板的数量，对6个实尺双肢冷弯C型钢吊架系统模型进行了静力加载试验，研究了吊架系统模型在设计均布荷载作用下和二次集中荷载作用下的变形模式和力学性能。试验结果表明，所有吊架系统模型在设计均布荷载作用下均满足承载力要求，在二次集中荷载作用下的整体和局部破坏模式分别为吊架梁的整体弯扭失稳和受压翼缘板的局部屈曲；在双肢冷弯C型钢腹板之间设置连接缀板能够提高吊架系统的刚度、极限承载力和变形能力。

Abstract: In order to study the feasibility of applying cold-formed thin-walled members in the hanger system of tall industrial plants， a double-limb cold-formed C-shaped steel hanger system was proposed. Considering different spans of the hanger beams， design load values， and the number of connecting batten plates between the webs of the C-sections， static load tests were conducted on six full-scale double-limb cold-formed C-shaped steel hanger system models to investigate their deformation patterns and mechanical properties under the design uniformly distributed loads and the successive concentrated loads. The test results indicated that all hanger system models met the bearing capacity requirements under the design uniformly distributed loads. The global and local failure modes under the successive concentrated loads were overall flexural-torsional buckling of the hanger beam and local buckling of the compressive flange plate， respectively. The installation of connecting batten plates between the double-limb cold-formed C-section steel webs enhanced the stiffness， ultimate bearing capacity and deformation capacity of the hanger system.
