This paper presents the results of an experimental dynamic campaign carried out on a reinforced concrete multi-span arch bridge. Five expeditious ambient vibration tests were conducted separately five spans (one test in each span) bridge using only six piezoelectric uniaxial accelerometers. Modal parameters identified through well-known Enhanced Frequency Domain Decomposition (EFDD) procedure d...

Although only a few of the ancient masonry arch bridges (MABs) are in fairly good condition today, many still use. Over time, declines and safety requirements change. Therefore, it is important to examine these under different influences. The strengthening MABs generally not essential. major cause damage their insufficient width height, thus, but usability that has restricted life-time MABs. th...
