EVALUATION OF A SHORT SPAN CONCRETE ARCH BRIDGE FOR REHABILITATION
暂无分享,去创建一个
A short span, open spandrel concrete arch bridge for local traffic has been found to have pieces of concrete fallen off from its components, and some reinforcing bars are exposed. There is no available information on the bridge's details. The safety of the bridge is of concern. Evaluation of the bridge consists of field measurement, load testing, and analysis. Load testing has been conducted and live load stresses in some components of the bridge have been measured. Results of a live load analysis by a finite element model compare satisfactorily with the measured values. The bridge is considered to have strength for the expected traffic loads. Minor repair to cover the exposed reinforcing bars is being recommended.
