Study of Pre-stressed Concrete Beam under Flexural Loading

Abstract

Today, saving energy in various fields has a special importance. Given the progresses made in the civil engineering, it can be mentioned in the optimal design of structures with the aim of using the minimum of material and human resources to achieve a maximum capacity of the structure. We can achieve more economic and even more beautiful design with designing and assigning the cross-section of the bridge as a changeable form due to the long length of some concrete bridge spans and thus the great number of changes in the internal forces of the cross-section. In this paper, pre-stressed transverse beams are modeled and optimized based on the principles and relations of the finite components. In this purpose, by using the results of a laboratory research, the mentioned beam is modeled in ABAQUS software and load variable in different beam is considered. For this aim, evaluate the effect of changing load of the tendons in the concrete beams performance and compared Pre-stressed concrete with normal concrete.
