随着国内风电行业发展规模日益壮大，风机功率逐渐增大，对下部支撑结构的承载、稳定性能也提出了更高的要求，钢-混凝土混合结构塔筒（上部纯钢塔，下部混凝土塔）应运而生。然而，由于需要现场拼装、灌浆，其建造效率低，后期维护成本高。基于此，提出了一种新型预应力钢管混凝土格构式风电塔架代替原有的钢-混凝土混合结构塔筒。四角柱采用预应力中空夹层钢管混凝土构件，增加刚度的同时减少了钢材和混凝土的用量，方便运输和吊装。中空部分作为预应力孔道进行通长整体张拉，增加结构稳定性及轴向滞回性能。目前 ...

钢框架中心支撑结构是一种双重抗侧力结构体系，为避免水平荷载作用下中心支撑斜杆发生失稳，提出了矩形钢管腹板开孔耗能支撑，其与钢框架采用高强螺栓连接，进而形成耗能支撑框架结构，耗能支撑发生破坏后易于替换。耗能支撑的耗能板件采用对称开孔与S形开孔两种形式，利用ABAQUS有限元软件，分析了耗能腹板厚度、长度、开孔间距等参数对耗能支撑以及支撑框架滞回性能的影响。研究结果表明：两种开孔形式的耗能支撑框架结构的支撑斜杆均未发生失稳，结构滞回曲线饱满，无捏缩现象 ...

波纹钢板剪力墙（Corrugated Steel Plate Shear Walls， 简称CSPSW）作为一种新型抗侧力构件，其几何构造在一定程度上起到了加劲肋作用，避免了板面加劲肋的焊接问题。两边连接横向CSPSW通过合理设计可实现先屈服后屈曲，具有两阶段受力特征，可获得较高的初始抗侧刚度和残余水平承载力。采用有限元软件ABAQUS对两边连接横向CSPSW的滞回性能进行系统的参数研究，提出了具有较优残余水平承载力的板型推荐建议。通过对影响CSPSW力学性能的高厚比（H/t）、跨高比（L/H）、波长 ...
