Abstract: Existing microplane models for concrete use three-dimensional spherical microplanes in the analysis of two-dimensional planar members as well as three-dimensional members. Also, they do not accurately describe the postcracking ...

Abstract: The nonlinear finite-element analysis of RC members subjected to cyclic loading requires complicated modeling and analytical techniques. In the present study, a simplified nonlinear analytical method using a truss model ...

Abstract: A new earthquake design method performing iterative calculations for secant stiffness was developed. Since basically the proposed design method uses linear analysis, it is convenient and stable in numerical analysis. ...
