The Tanaro Bridge, an 18span 225m long bridge on the Tanaro river in north-western Italy, presented elements of interest: i) the barrel divided into adjacent arches; ii) transverse tie bars and internal spandrels connecting the three parts of the barrels. Its demolition, in 2003, gave the opportunity of performing dynamic tests on a couple of spans at two stages of demolition: i) fill removed; ii) fill and internal spandrels removed. Without the uncertain contribution of the fill, some features of the mechanical response of masonry bridges is discussed and the efficiency of tie bars and internal spandrels is addressed. The data provided can be useful for safety assessment procedures

Abstract
The Tanaro Bridge, an 18span 225m long bridge on the Tanaro river in north-western Italy, presented elements of interest: i) the barrel divided into adjacent arches; ii) transverse tie bars and internal spandrels connecting the three parts of the barrels. Its demolition, in 2003, gave the opportunity of performing dynamic tests on a couple of spans at two stages of demolition: i) fill removed; ii) fill and internal spandrels removed. Without the uncertain contribution of the fill, some features of the mechanical response of masonry bridges is discussed and the efficiency of tie bars and internal spandrels is addressed. The data provided can be useful for safety assessment procedures
