Plastic Hinge Length for Lightly Reinforced C-Shaped Concrete 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...

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...

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...

Use of Supplemental Damping Devices for Seismic Strengthening of Lightly Reinforced Concrete Frames

1. ABSTRACT Devices which can add damping and strengthen structural systems, without changes to the existing components, were found recently extremely useful in retrofitting lightly reinforced frames and other structures. Some damping devices were developed purposely for building structures, however, many more were adapted from use in other industries such as the military and aerospace. Damping...
