Concrete Bridge in Abaqus Software Modeling and SpatialVariations of such Structures against Earthquake Force

Given the key importance of critical bridges in the arteries of transport system of each countryand due to the high cost of building and maintaining them need to study the bridges there againstdestructive agents. The design and use of the bridge, especially on highways and freeways hasincreased and how to design structures to withstand various forces exerted such as the earthquakeis of great importance. There are several factors that can cause damage to these structures, themost important of these factors can be corrosion of reinforcement steel, non-compliance with theAdministrative Regulations and noted, to prevent damage to the listed can be used with asoftware finite element modeling the structure and various forces exerted against the force of theearthquake. How the structures studied in different modes to run after the destruction ofstructures largely prevented. In this study, a concrete bridge true size, consisting of a concretedeck on the 10 cylindrical concrete bases is placed; using the Abaqus finite element modelingsoftware is sent. In both cases the structures against arthquake forces were eventually shiftdiagram before and after retrofitting structures have been analyzed. According to the results ofthe analysis are expected to shift after retrofitting structures with FRP composites reduced.
