| Abstract: | Considering the number of members, linear stiffness of every member and beam-column stiff- ness ratio at distal rigid nodes of member, a unified formula was derived to calculate rotational stiffness and transmission coefficient of beam end. The frame structure was divided into some single column structures to compute its internal force under vertical loads. The method proposed had no scope limitation of beam-column linear stiffness ratio. This method had the advantages of high accuracy, small computational amount and wide range of use. |
