| Research Abstract |
Discrete-like crack analysis method is developed to visualize damage conditions of reinforced concrete structures subjected to seismic loads. The method is extended to three-dimensional hysteresis response analyses. Precise and rapid analyses of crack conditions under repeated cyclic loads are realized by developing a numerical program through improvements on stress concentration/release estimations, crack crossing estimations, bond splitting judgments, and bond stress-slip assumptions.
