Abstract

There are a large number of old arch bridges in Iran designed to carry the service loads that have been increased in the past decades. Capacity assessment of these bridges has become a vital need. Due to their complex behavior, essential field and loading tests are required. An accurate and appropriate modeling of these types of bridges was the first key paid attention to, in this research. Parameters such as number, length and geometry of spans and strength of materials are the most significant features to achieve this goal. Field load testing of old railway bridge in km–24 of Tehran–Qom railway have revealed important characteristics of the bridge such as primary stiffness, rigidity and pattern of fraction. The bridge is a plain concrete arch with five identical six-meter spans. The effect of number of spans on the yielding strength of the bridge has been carried out using ANSYS software. Based on the results obtained, a plain concrete arch bridge with a single span has a totally different behavior with the multi span ones. Also it has been revealed that bridges with more number of spans have less yielding strength and higher amount of crown displacement value. At last, novel relations for computing the yield strength and displacement value of six-meter span plain concrete bridges have been suggested.
