The Characteristics of Dynamic Behaviors for the Spatial Structures under Seismic Loads
- 발행 : 2005.04.01
초록
The earthquake-resistant structural systems have to ensure the sufficient stiffness and ductility for the stability For those purposes, recently, the seismic isolation system to reduce earthquake energy has been used. So, it is necessary to examine the characteristics of dynamic behavior of spatial structures governed by higher modes rather than lower modes different from the cases of high rise buildings. The objectives of this paper are to inspect the efficiency of the equivalent model method according to the various earthquake loads and half-open angles. Moreover it is examined the dynamic behaviors according to change the mass and the stiffness of sub-structures as a fundamental study of performance design for the spatial structures. Finally, seismic isolation system is applied to boundary parts of roof system and sub-structure to obtain the target performance.
