A Review of Existing Masonry Arch Bridges in Croatia

This study offers a review of masonry arch bridges in Croatia, it presents their most common typologies, geometric characteristics, and damages. Data about bridges have been collected from official institutions, state archives, and conservation institutes. Statistical analysis considering materials, arch geometry, arch thickness, number of spans, and superstructure type was conducted using collected data. The most common typologies are stone bridges with constant arch thickness, closed spandrel walls, and circular arch for the single-span and segmental arch for multi-span bridges. Additional data about geometry and damage of road brickwork bridges has been obtained with a rapid visual in-situ inspection. Observed damages indicate the need for further investigation for purpose of better understanding the capacity of these bridges, to secure their safe use through adequate maintenance and retrofitting.
