某钢网架加固设计

open access: yesJianzhu Gangjiegou Jinzhan
某网架因施工遗留问题和使用荷载的增大,导致结构存在质量安全隐患。系统地介绍了网架加固方案:受压杆件采用薄壁槽钢、薄壁矩形管或角钢作为外加约束单元的增大截面法进行加固,受拉杆件采用新增双拼槽钢的增大截面法进行加固,螺栓采用在原螺栓球节点上焊接鼓筒节点或增设高强对拉螺杆的方法进行加固。采用MST和NIDA软件进行了结构模型验证并使用直接分析法对网架进行承载力计算,并对压杆加固方案进行了精细化有限元分析,对比分析了加固杆件和未加固杆件的荷载-位移曲线和破坏模式。结果表明:压杆加固后,构件承载力提高了15 ...
