矩形钢管-波折钢板组合墙端顶部承压性能与传力路径试验研究

Jianzhu Gangjiegou Jinzhan
矩形钢管-波折钢板组合墙是一种新型剪力墙，通过横置波折钢板连接两侧钢管形成预制钢构件，然后在钢管内及双波折钢板间填充混凝土形成组合墙。为研究矩形钢管-波折钢板组合墙在竖向荷载下的承载性能，以管间墙肢长度和栓钉间距为变化参数，完成了5个仅在墙端钢管混凝土柱顶加载的组合剪力墙试件抗压静力试验。在试验过程中，主要对加载端柱的竖向位移和组合墙三个不同高度截面应变进行了测量。试验结果表明，竖向荷载由组合墙边缘构件矩形钢管混凝土柱传递至剪力墙整体截面，需要一定的传力长度 ...

螺栓连接方钢管混凝土柱-钢梁组合框架结构拟静力有限元分析

Jianzhu Gangjiegou Jinzhan
本文应用ABAQUS软件建立了1层1跨螺栓连接方钢管混凝土柱-钢梁组合框架结构的三维精细有限元模型来进行拟静力分析，螺杆、螺母等细小构件都采用实体建模。模型充分考虑了钢管对核心混凝土的约束作用、螺杆与螺母的预紧力作用以及螺栓与T形件、钢管、钢梁的摩擦接触作用，模型分析的破坏形态、荷载-位移滞回曲线、刚度退化-位移曲线等计算结果与已有拟静力试验结果符合较好。在此基础上，进一步分析了组合框架结构的螺栓滑移情况、柱轴压比、钢管横向变形系数、核心混凝土应力-应变曲线、结构损伤、塑性耗能分配机制。结果表明 ...

内置蜂窝芯-钢管暗柱冷弯型钢组合墙体抗剪性能研究

Jianzhu Gangjiegou Jinzhan
基于蜂窝夹心冷弯薄壁型钢组合墙体的优势，提出了一种内置蜂窝芯-钢管暗柱冷弯型钢组合墙体，实现了框架柱与墙体的一体化设计。为了研究该组合墙体的抗剪性能，采用ABAQUS软件建立了组合墙体的有限元模型，并分析了两端暗柱对组合墙体破坏模式和受力机理的影响；通过改变内置蜂窝芯与钢管暗柱的连接方式、自攻螺钉布置和暗柱与边立柱壁厚比等参数进行了墙体抗剪性能的变参数分析。研究结果表明：两端增设钢管暗柱可以更好地发挥蜂窝芯的抗剪作用，抗剪承载力提升了22.50 ...
