Abstract

Alaa El Deen Amr Hussein, On A Finite element analysis for reinforced concrete joint, Structural department Faculty of Engineering Ain Shams university. The nonlinear behavior that associates reinforced concrete structures through loading stages due to changes in material properties and geometrical deformations are one of the most controlling criteria in the behavior of reinforced concrete structures. Efforts have been done to model this behavior, and these efforts were the basis of the present research beside a trial to develop new solving technique and analytical computer program to save time and be more precise .A reinforced concrete joint was chosen as a case study and many steps were taken to judge the developed program. The previous efforts were studied, A theoretical assumptions were assumed for the new method of analysis considering the structure is entering every new load increment with new deformed calculated geometry, and assuming a material stiffness matrix that changes its material components with load increments. An experimental reference for the studied case was done to give a datum and a real behavior to be used to calibrate the developed computer program. A computer program was developed using JAVA language as well as assembly of its parts and adjusting to comply with the new analytical assumptions beside using the program as an easy input - output tool in the research field, the program is explained and attached. The research examined the software and calibrates its suitability by comparing it with that reached from experimental study, the case study gave a good correlation with the experimental results and the previous studies for the failure loads but still more efforts are needed to reach the ideal representation for the crack deflection and behavior Alaa El Deen Amr Hussein, On A Finite element analysis for reinforced concrete joint, Structural department Faculty of Engineering Ain Shams university.
