“…It consists of a trilinear envelope curve with stiffness and strength degradation with pinching response, which is always observable in the reinforced concrete elements subjected to shear forces. The model is similar to the one proposed by D'Ambrisi and Filippou [29]** and Lee et al [31] except for both the influence of axial force on the shear relationship, here neglected, and the use of a trilinear backbone curve.…”

This paper deals with the assessment of the seismic response of a portal frame pier belonging to an old reinforced\ud concrete viaduct. A series of tests, consisting of cyclically imposed displacements, were carried out\ud on three 1:4 scale mock-ups. The objective of the experimental campaign is twofold: (1) identification and evaluation of the local failure mechanisms and (2) calibration of a numerical model including all observed nonlinear phenomena. The experimental results show that the shear strength of the transverse beam and of\ud the beam–column joints characterizes the post-elastic behavior of the piers. Other phenomena, like bond-slip\ud and buckling of the longitudinal bars of the columns, typical of old reinforced concrete structures have also\ud been observed. Finally, a numerical model, built in OpenSEES, was calibrated to reproduce in a satisfactory\ud way the experimental results and to provide a reliable tool for the evaluation of the seismic response of the\ud pier

“…Both microscopic finite element models and macroscopic models can be used for the nonlinear analysis of wall systems. The microscopic finite element models can provide detailed local responses of walls with accuracy (Park and Klingner 1997;Okamura and Maekawa 1991;Stevens et al 1991;Feenstra and de Borst 1993;Mansour and Hsu 2005;Wong and Vecchio 2002;Palermo and Vecchio 2007;Petrangeli et al 1999;D'Ambrisi and Filippou 1999). However, it requires tremendous efforts and time for modeling and numerical computations.…”

During earthquake, reinforced concrete walls show complicated post-yield behavior varying with shear span-to-depth ratio, re-bar detail, and loading condition. In the present study, a macro-model for the nonlinear analysis of multi-story wall structures was developed. To conveniently describe the coupled flexure-compression and shear responses, a reinforced concrete wall was idealized with longitudinal and diagonal uniaxial elements. Simplified cyclic material models were used to describe the cyclic behavior of concrete and re-bars. For verification, the proposed method was applied to various existing test specimens of isolated and coupled walls. The results showed that the predictions agreed well with the test results including the load-carrying capacity, deformation capacity, and failure mode. Further the proposed model was applied to an existing wall structure tested on a shaking table. Three-dimensional nonlinear time history analyses using the proposed model were performed for the test specimen. The time history responses of the proposed method agreed with the test results including the lateral displacements and base shear.

“…Both of these approaches appear to be inadequate for modeling the columns dominated in shear or shear-flexure behavior since the stiffness degradation, pinching behavior, and strength deterioration as a result of SFI are not captured [10]. Inelastic shear behavior has been included with the nonlinear flexural behavior in several previous studies ( [11][12][13][14] among others). Improvements have been made to include the SFI effects for fiber-based element [15][16][17][18] and Macro-element model [19].…”

This paper presents the methodology, model description, and calibration as well as the application of a coupled hysteretic model to account for nonlinear shear-flexure interactive behavior of RC columns under earthquakes, a critical consideration for seismic demand evaluation of bridges. The proposed hysteretic model consists of a flexure and a shear spring coupled at element level, whose nonlinear behavior are governed by the primary curves and a set of loading/unloading rules to capture the pinching, stiffness softening, and strength deterioration of columns due to combined effects of axial load, shear force, and bending moment. The shear-flexure interaction (SFI) is considered both at section level when theoretically generating the primary curves and at element level through global and local equilibrium. The model is implemented in a displacement-based finite element framework and calibrated against a large number of column specimens from static cyclic tests to dynamic shake table tests. The numerical predictions by the proposed model show very good agreement with experimental data for both flexure-and shear-dominated columns. The application of the proposed model for seismic assessment of bridges has been successfully demonstrated for a realistic prototype bridge. The factors affecting the SFI and its significance on bridge system response are also discussed.
