SEISMIC BEHAVIOR PREDICTIONS OF STRUCTURES: A LOCAL NONLINEAR MECHANISM APPROACH. IN: FINITE ELEMENT ANALYSIS OF REINFORCED CONCRETE STRUCTURES

The analysis of reinforced concrete structures subjected to seismic loading is discussed in this paper. The expressions of two constitutive relations based on damage mechanics are exposed. Introduced at the local level are physical behavior such as crack closure and frictional sliding, and their influence towards structural computations (global damping) are exemplified through comparisons with experimental data.
