RISHigh‐Strength Concrete Columns Confined by Rectangular Ties
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study of the behavior of large‐scale high‐strength concrete columns confined by rectangular ties under concentric loading. Effects of key variables such as the concrete compressive ...
Uniaxial Confinement Model for Normal- and High-Strength Concrete Columns
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new confinement model based on strain compatibility and transverse force equilibrium. This new approach is capable of predicting the effectiveness of transverse reinforcement, which is key in modeling ...
Damage Identification in a Truss Tower by Regularized Model Updating
Publisher: American Society of Civil Engineers
Abstract: This paper presents a sensitivity-based damage identification of a three-dimensional truss tower tested in the laboratory. A finite-element model is updated by modal parameters obtained from ambient vibration measurements. ...
Stress-Strain Model for Confined High-Strength Concrete
Publisher: American Society of Civil Engineers
Abstract: A stress-strain model for confined high-strength concrete has been developed and calibrated against the test results from 50 large-scale high-strength concrete tied columns tested under concentric loading. The effects of ...
Experimental Evaluation of Inelastic Higher-Mode Effects on the Seismic Behavior of RC Structural Walls
Publisher: ASCE
Abstract: Most midrise and high-rise reinforced concrete (RC) buildings rely on RC structural walls as their seismic force resisting system. The contribution of higher lateral modes to the elastic response of RC structural walls ...
Damage Mechanics Modeling of Nonlinear Seismic Behavior of Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: Performance-based design of structures is becoming the preferred seismic design method. Its use requires special numerical programs capable of predicting the performance of structures during a seismic event well into the ...
Dynamic Testing Procedures for Highway Bridges Using Traffic Loads
Publisher: American Society of Civil Engineers
Abstract: Dynamic bridge testing techniques used at the University of Sherbrooke on a series of highway bridges in the province of Quebec, Canada, are presented. These procedures were developed to obtain a reliable evaluation of the ...
Metamodel-Based Seismic Fragility Analysis of Concrete Gravity Dams
Publisher: ASCE
Abstract: Probabilistic methods, such as fragility analysis, have been developed as a promising alternative for the seismic assessment of dam-type structures. However, given the costly reevaluation of the numerical model simulations, ...
Closure to “Strain Localization in Confined High‐Strength Concrete Columns” by Daniel Cusson, François de Larrard, Claude Boulay, and Patrick Paultre

Seismic Fragility of Concrete Gravity Dams with Spatial Variation of Angle of Friction: Case Study
Publisher: American Society of Civil Engineers
Abstract: Concrete gravity dams are essential infrastructure components and because of earlier design practices, they may be vulnerable to future earthquake events. Therefore, their vulnerability is important to characterize, ...
