This research designed, analyzed and detailed concrete bridge substructures in Eurocodes using manual and computer methods. The design was done focusing only on the substructure being the lower part of a bridge. It is the one that supports the horizontal spans of the bridge by carrying all the weights of the superstructural members. In this work, a Java based computer program was developed to design, analyze and detail the bridge substructures. The Java computer program focused on the design and analysis of the abutments and pier caps using Courbon’s method. The program made use of algorithms and visualization techniques. The bridge spans considered, ranged from 23.2m to 40m. The maximum design bending moments, maximum shear forces and the axial forces were 935.90kNm, 366.69kN and 682.48kN respectively. The manual analyses and designs were done for 23.2m, 25m, 30m, 35m and 40m bridge spans. These results were then compared to those obtained from the java computer program. It was seen that the results of both analyses and designs from manual procedure and java computer program, were relatively the same.This showed that, the developed Java computer program have been validated with Eurocodes BS EN 1992-1-1, BS EN 1991-1-4, and BS EN 1991-2, and can serve as a reliable and handy tool for the analyses and designs of bridge substructures. Therefore, BS EN 1991-1-4, BS EN 1992-1-1, and BS EN 1991-2, can easily be applied by using this Java computer program to design bridge substructures based on actor of safety, serviceability and economy. The Java computer program will also contribute to the performance of bridge structure in terms of suitability and reliability. It also gives quick and accurate analysis and design of bridge substructures.
