Analytical Study of Reinforced Concrete Continuous Deep Beams

Abstract

Nonlinear finite element analyses is carried out using the ANSYS11 program to predict the ultimate load for two different types of reinforced concrete continuous two-span deep beams. Results of comparing analytical with experimental data demonstrates the accuracy of the program. The effects of longitudinal reinforcement and web openings are studied and showed that the longitudinal reinforcement at top and middle region has little effect on the ultimate load, and the effect of web opening location has great effect on the ultimate load especially when the load path passes through the openings centerline. Web opening location also has great effect on values and distribution of shear and normal stresses especially at opening region.
