摘要
对有7个及7个以下的可转动结点的刚架,给出了分配传递无限次的杆端弯矩极限值的表达式及其算例.该极限公式既能手算又便于电算,可应用于高层框架分层后的计算.
A formula for the limit value of bending moments at bar ends obtained by infinite distribution and transmission of unbalanced moments is derived for the frame with seven or fewer rotatable joints, and corresponding examples are given. The method is convenient for computer and manual calculation, and suitable for calculation of highrising rigid frames after layer division.
