Assessment of Bhaleth Bridge using Mechanism Method

摘要

The arch bridges built in ancient times are an integral part of infrastructure. For many reasons including changing trend in the use of materials, design philosophy, relative costs and maintenance, the masonry arches are almost out of use. However there is a renewed interest in performance of existing masonry arch bridges. The paper presents a brief review of the existing methods of assessment and analysis including the analysis of two masonry arch bridges using these methods. The bridges have been analysed using the proposed mechanism procedure by the author. The results obtained are in agreement with other methods of analysis.
