摘要
本文提出了半刚性连接钢框架位移和内力计算的刚度矩阵法,另外还提出了在水平荷载和竖直荷载作用下内力的简化计算方法。水平荷载作用下内力的计算用替代刚架法,竖直荷载作用下内力的计算可用弯矩分配法或分层法。本文对常见的五种高强螺栓梁柱节点连接的连接刚度进行了综合计算分析,总结出了在正常使用荷载下横梁线刚度同节点刚度比值的取值范围。
Displacement of stress-resultants computation technique of semi-rigidly connected steel frames inclucing stiffness matrix method,hand calculation method has been proposed. Hand calculation includes substitute rigid frame method under horizontal loads and moment distribution or decomposed storey method under vertical loads. Connection stiffness for five widely used type has systematically computed and practical values of beam stiffness to column stiffness has been summarized and issued.
