钢结构支撑节点板与梁柱连接的内力计算方法比较

Algorithm Comparison of Inner Force of the Joint Connecting Steel Structure Backup Nodal Pad with Beam and Column

对钢结构支撑节点板与梁、柱连接处内力的计算,国内常用的简化计算法所得的结果比用美国AISC建议的均匀力法大,虽然安全系数较高,但也可能会造成一定的材料浪费。因此,从优化设计的角度出发,对斜向支撑内力较大的节点,不妨参考均匀力法或寻找其他更接近实际情况的计算方法。

As for the calculation of the inner force of the joint connecting steel structure backup nodal pad with beam and column, the numerical value resulting from simplified algorithm, which is often used in China, is larger than the one resulting from homogeneous force algorithm, which is suggested by AISC from America. Although the security coefficient is higher, it may still result in wasting some matsrials. Therefore, from the angle of optimum design, the inner force calculation of the joint with more lateral support power might as well refer to homogeneous force algo-rithm or other algorithms closer to practical situations.
