Masonry Arch Assessment (BD 21/01)

This standard provides guidance on the assessment of the load-carrying capacity of masonry arch bridges.

BD 21/01 includes specific methodologies for evaluating the structural integrity and load capacity of masonry arch bridges. These assessments consider the unique characteristics of arch construction, material properties, and historical performance. The standard helps engineers determine if an arch bridge can safely carry current and future traffic loads, often involving detailed structural analysis and site investigations.
