概要 |
In recent years, the hybrid rigid frame bridge, which consist of a continuous girders and RC piers, has been widely used due to its low cost and its seismic safety. On the other hand, structures that ...have the spaces below their viaducts can be used in urban highways, the application of RC rigid frame piers is effective. However, no basic research has been performed and no design method has been established so far for a hybrid frame piers consisting of a few girders bridge and RC rigid frame piers. Therefore, we examined the shear loading capacity of SRC cross beam and the flexural loading capacity of the knee joint in the hybrid frame piers by the loading test and the FEM analysis. The results show that the shearing force does not change even if the full web steel frame of various types is used to SRC cross beam, and clarified the load transfer mechanism and the stiffening structure of knee joint with a main I-girder.続きを見る
