AN INTEGRATED COMPUTATIONAL SYSTEM FOR MASS/ENERGY GENERATION, TRANSPORT, AND MECHANICS OF MATERIALS AND STRUCTURES (Translation from Proceedings of JSCE, No.627/V-44, August 1999) Tetsuya ISHIDA Koichi MAEKAWA The authors present an integrated computational system consisting of a 3D FE structural analysis program and a 3D FE thermo -hygro physical analysis system which can model the development and deterioration of concrete materials performance. The thermo -dynamic process provides solutions for temperature, pore pressure, pore distributions, and other material properties in both 3D space and time. By passing this information to the structural mechanics process, the stress and damage to RC members caused by temperature changes and shrinkage can be obtained. The generation of cracks changes the material properties of mass transport, which are controlled by thermo -physics. This proposed integrated system can be used for the simultaneous evaluation of overall structural and material performances without distinguishing between structure and durability. Keywords: Durability, structural performance, parallel computation, crack, mass transport Tetsuya Ishida is an assistant lecturer in the Department of Civil Engineering at University of Tokyo, Japan.
