Abstract: Two different methods considering the second effect of staggered RC frame structure was used. One is elastic finite element method of reduced rigidity( elastic analysis method considering the second order effect), and the other is the method utilizing the eccentricity enhancement coefficient of column section( the conventional method proposed in the code which considering the second effect by the determination of the calculating length).The scope of application using the conventional method to consider the second order effect of staggered RC frame structure, and the confirmation method of calculating length of the column were analyzed. Correspondingly the design calculating method suggestion is also proposed.
Keywords: staggered RC frame structure; the second order effect; calculating length
