Abstract: In the designing of the simple beam-arch composite bridge of the 100.5m span in the out Suzhou City Ring Road, Jiangsu Province, the results achieved by calculation, analysis of the structure, and test of the load on the real bridge is int roduced in this paper. We use steel pipe concrete for the arch rib, prest ressed concrete box beam for the stiffened girder, OVM anchorage and low relaxation tendon for the longitudinal prest ressed cable. In the construction of the bridge, the method of the beam first, the arch af terwards, and with little scaffords was used. The results of test have approximately coincide with the calculations and the chief section of the bridge had no crackles.

Key words: simple beam-arch composite bridge, steel pipe concrete
