Abstract
In view of the present big railway stations with large span steel staircase structures, which are compared and analyzed by means of independent calculation model and combined station building calculation model, this paper reveals the differences in internal bar stress and self-vibration characteristics of the staircase structure under complicated boundary conditions. The results show that the bearing stiffness of stair poses significantly influence on the internal force and the self-vibration characteristics of the structure, which is one of the important factors in structural design. Meanwhile, it is suggested that similar project staircase structure design should employ combithe main structure of conjoint analysis method, in order to obtain the stair structure mechanics response of the real complicated boundary conditions.关键词
