| Research Abstract |
A design method to decide suitable structure specifications of steel bellows was suggested for simple girders and continuous girders. This design method makes it possible to use comparatively small bellows by setting the largest response displacement caused by big earthquakes in consideration for the temperature expansion of girders and fatigue strength of bellows.
Simultaneous loading experiments were carried out and degree of strength degradation is grasped in comparison with single axial loading experiments. Axial direction fatigue tests were carried out using various bellows made of different steel materials, and fundamental characteristics of fatigue strength of bellows are obtained.
