Experimental Studies and Vulnerability Assessment of Timber-Arched Lounge Bridges
There are many preserved timber-arched lounge bridges in China and some of these bridges are hundreds of years old. The woven arch is the main bearing structure of a timber-arched lounge bridge. Few studies still exist about woven arch mechanical performance, a fact that contributes to the improper repair. This article concerns the structural performance of the woven arch. The results of experimental studies on deformation, stress distribution, force-transferring mechanism, and failure modes were presented. Two woven arch models with and without П-shape braces under symmetrical load and asymmetrical load were investigated. The results indicated that the woven arch had high bearing capacity, especially under symmetrical load. The comparison of experimental results obtained for models with and without brace showed that braces modified the failure mechanism and increased the load carrying capacity and integrity. Based on the failure conditions observed experimentally, limit criteria were defined in order to facilitate vulnerability assessment of timber lounge bridges.
