Plastic hinge analysis for lightly reinforced and unconfined concrete structural walls

plastic hinge rotation capacity of reinforced concrete beams

a parametric study is performed to assess the influence of the tension reinforcement index, ( ω = ρ fy /f bc), and the bending moment distribution (loading type) on the ultimate deformation characteristics of reinforced concrete (rc) beams. the analytical results for 15 simply supported beams with different amounts of tension reinforcement ratio under three different loading conditions are pres...

Simulation of Nonlinear Seismic Response of Reinforced Concrete Structural Walls

In this study the performance of three macro-models in predicting the nonlinear response of different walls is investigated. The macro-models used are: Equivalent Beam Model, Multiple Vertical Line Element Model and a shear panel model developed by Massone et al. (2006). The walls are classified as slender, intermediate, and squat walls according to their shear-span ratio. First, three single w...

Plastic hinge models for the seismic assessment of reinforced concrete wall-type piers with detailing deficiencies

Plastic hinge models are widely used in earthquake engineering to predict the load-deformation relationships of reinforced concrete members. For the seismic assessment of bridges, it is appealing to use those relatively simple models if the response is predicted with sufficient accuracy. The applicability of these models to wall-type bridge piers with weak seismic detailing is examined. Flexura...

Numerical Analysis of the ElectromagneticShielding Effect of Reinforced Concrete Walls

A Macro-model for Nonlinear Analysis of 3D Reinforced Concrete Shear Walls

Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...
