TEST OF STW-RC COMPOSITE MODEL ARCH UNDER NON-SYMMETRIC IN-PLANE LOADS

摘要

The heavy dead weight has restricted the development of the concrete arch bridge. A new composite arch of steel truss web and concrete flange (STW-RC) was proposed. Meanwhile a test of STW-RC arch model under the non-symmetric in-plane loads was carried out based on the trial design. The results show that this new composite arch bridge was feasible. But node played such a key role in the capacity that some measurements to strengthen it were required.
