| Abstract |
The objectives of this research are to verify the structural stability and estimate the resisting performance of Stressed-Arch system during the stabilizing process.
Full scale models are taken to obtain the objective shape by the Dynamic Relaxation Method and to confirm compressive performance of top chord members by experiments. As a result, it measured more strain than yielding strain at the extreme fiber of top chord member on the crown, but it is shown that members have the sufficiently compressive resisting performance as well as a considerable strain recovery capacity under unloading. Therefore, it is confirmed that Stressed-Arch system apparently have sufficient range of the structural capacity, but it is required that the elasto-plastic behavior of this system must be verified more detailed by numerical analysis and experiments. |
