Significance of Nonlinear Modeling of R/C Columns to Seismic Response

Document Type: Proceeding Paper

Part of: Dynamic Response of Structures

Abstract:

Columns in reinforced concrete (R/C) structures exhibit complex hysteretic behavior during earthquakes. This can significantly influence predictions of overall response and damage distribution. Current analysis approaches often simplify this behavior, failing to properly model the influence of axial load on strength and stiffness as well as other important phenomenon. A finite element model is presented that overcomes some of these limitations. Emphasis is placed herein on comparisons of experimental data with analytical results obtained using the new element as well as with more conventional models. Topics requiring further research are identified, as are improvements required for the proposed scheme.
