Jianzhu Gangjiegou Jinzhan地震作用下钢桥墩根部易发生屈曲破坏且震后难以快速修复。基于可恢复功能理念与钢桥墩的受力特征，提出一种具备震后易恢复功能的新型箱型钢桥墩。此新型桥墩通过设置可更换的加劲耗能壁板以增强结构的耗能与变形能力，且震后能够快捷更换受损的耗能壁板以恢复桥墩力学性能。为研究设置加劲耗能壁板的箱型钢墩柱的抗震性能，选取耗能壁板上加劲肋的布置形式、轴压比及耗能板强度等作为影响参数进行拟静力试验，且通过有限元数值模拟，综合探讨此类新型试件在地震作用下的力学性能；并对比分析新型桥墩的受力特点和破坏机理 ...

Jianzhu Gangjiegou Jinzhan针对PEC梁力学性能及施工过程中的薄弱点，本文提出了将PEC梁翼缘卷边并在腹板开设蜂窝孔的构造。考虑剪跨比与箍筋间距因素的影响，对3根不同剪跨比与箍筋间距的翼缘卷边蜂窝开孔PEC梁进行了拟静力试验。观察了试件不同加载阶段的破坏特征以及荷载-位移曲线，根据试验数据分析试件的各项力学性能指标。试验结果表明：翼缘卷边蜂窝开孔PEC梁具有较好的承载能力与延性，破坏模式是根部混凝土开裂压溃和翼缘卷边屈曲撕裂；剪跨比主要影响试件的承载力、刚度退化，箍筋间距主要影响耗能能力，两者对裂缝发展都有较大影响。

Jianzhu Gangjiegou Jinzhan为研究H型钢钢骨混凝土柱在压弯剪扭复合受力作用下的抗震性能，对7个H型钢钢骨混凝土柱和1个钢筋混凝土柱进行拟静力试验，以探究扭弯比、轴压比、配箍率等对柱试件抗震性能的影响。分析了柱试件在低周反复加载试验中裂缝产生和发展的规律及破坏特征，讨论了各试件的扭矩-扭率滞回曲线、骨架曲线、耗能能力、延性、刚度退化和损伤分析。结果表明：H型钢钢骨混凝土（HSRC）柱在复合受力状态下均发生受扭破坏，其扭矩-扭率滞回曲线呈现捏拢的“S”形。但相较普通钢筋混凝土试件，其承载能力和抗震性能更优。提升扭弯比、轴压比 ...
