中文摘要：

基于薄壁钢板组合截面PEC柱的研究成果，为更好满足受压构件双向等刚度原则和进一步改善薄壁钢板组合截面PEC柱的力学性能，提出采用翼缘卷边和设置外拉结板条的新型卷边钢板组合截面PEC柱。对变化拉结板条间距的3个卷边钢板组合截面PEC柱（弱轴）足尺试件在恒定轴压下进行水平循环荷载的滞回性能试验。观察记录了各试件加载过程中钢板组合截面翼缘局部屈曲和混凝土裂缝开展与压溃现象，得到试件的荷载．位移滞回曲线。根据试验结果分析试件的承载力、抗侧刚度、构件抗震延性与耗能、变形规律和破坏模式等力学性能。结果表明：试验卷边PEC柱试件充分发挥了薄板局部屈曲后性能，具有良好的变形能力与耗散地震能的双重功效；构件的破坏模式为柱脚部位卷边钢板组合截面翼缘局部屈曲区域不断增加，柱脚混凝土压溃面积加大和拉结板条屈服。研究进一步丰富了PEC柱研究成果，为PEC组合柱设计规范的制订和工程应用提供了理论依据。

英文摘要：

According to the achievements obtained in the research of PEC columns fabricated with thin-walled built-up section, flange crimping was used to improve the mechanical performance and to fulfill biaxial equivalent rigidity. 3 specimens with various spacing for transverse steel sheet links were designed and fabricated by full-scale, which represents the middle-storey column in the frame structure. The tests on the specimens were conducted under lateral cyclic loading along the weak axis with constant axial compression, and the hysteretic curves were derived. Base on the test results, the specimens＇ global behaviors were analyzed, including the load-carrying capacity, lateral-resistant stiffness, the seismic ductility, energy-dissipation capacity, the deformation pattern and the failure mode. It was concluded that the specimens exhibited sound deformation and energy-dissipation capacity; the failure mode was indicated by local buckling in flange of crimping thin-walled built-up section, crushing and spalling of concrete and yielding of transverse steel sheet links at footing of column. The study presents a more theoretical basis for the amendment of the specification and engineering practice of the structure comprised of PEC Columns.
