| Research Abstract |
Previous analytical models for FEM analyses of reinforced concrete structure were reviewed. The problems were extracted from the review. Basic experiments were carried out in order to solve the problems. The experimental results were compiled and analyzed, and rational analytical models were developed. The analytical modeles, which are effective for the analytical subjects in reinforced concrete members such as columns, beams, beam-column joints, shear walls were proposed. The research results are as follows.
1. Basic Experiments and Modeling (Morita, Tanigawa) (1) Flow Analysis of fresh Concrete (Tanigawa) (2) Analysis of Thermal and shrinkage stresses in Concrete at Early Age (takiguchi) (3) Modeling of Tensile Stress Transfer between Cracks and Application (Fujii) (4) Resistance Mechanisms at Cracking Zone (Matsuzaki) (5) Effect of Shear Slip on Opening and Closing Behavior of a Crack (Noguchi) (6) Cyclic Stress Transfer across Crack Surfaces of Concrete (Namura) (7) Aggregate Interlock on Crack Surfaces (Watanabe) (8) Constitutive Law of Cracked Concrete (Shirai) (9) Deterioration of Compressive Characteristics of Reinforced Concrete (Noguchi) (10) Evaluation of Compressive Strength and Deformation in Reinforced Concrete Shear Walls (Watanabe) (11) Correlation between Bond and Dowel Action between Concrete and Deformed Bar (Kobayashi, Noguchi)
