5、形式。这种连接形式的整体性较好，约束能力较强，应用比较广泛。中心支撑是结构中的主要抗侧力构件，承受大部分水平荷载，其中一部分通过支撑连接件传递到梁和柱上。为了便于支撑的连接，保证连接质量，一般增大连接件腹板的高度。连接件腹板高度的增大对节点及支撑内力传递的影响，采用的计算方法和构造要求使连接件更均匀合理地传递支撑轴力是非常具有实际意义和研究价值。其中一部分水平荷载通过支撑连接件传递到支撑与梁柱相交的节点域上，而现行规范和图集并没有给出支撑与梁柱相交节点域的设计方法和相应的构造要求，设计人员主要凭借经验进行设计，缺乏理论依据。为此，本文分别对支撑连接件和支撑与梁相交节点域的受力性能进行了深入分析

7、提出相应的设计构造建议。3、 结合相关的理论基础和以上两点的有限元分析，综合考虑分析参数的影响，关于支托式连接支撑节点的设计，提出相应的计算方法及设计建议，为相关的规范和图集提供参考依据。关键词：钢结构；框架；中心支撑；连接件；节点域Abstract:With economic development and technological progress, Chinas steel production has increased.
