RISA Gradient Inelastic Flexibility-Based Frame Element Formulation
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel gradient inelastic beam theory and a corresponding flexibility-based (FB) frame element formulation to treat major weaknesses of existing FB formulations in the presence of softening section ...
Refined Gradient Inelastic Flexibility-Based Formulation for Members Subjected to Arbitrary Loading
Publisher: American Society of Civil Engineers
Abstract: This paper advances the gradient inelastic (GI) flexibility-based (FB) frame element formulation, which focused on monotonic loading conditions, to capture member responses to arbitrary (nonmonotonic) loading conditions. ...
A Gradient Inelastic Flexibility-Based Frame Element Formulation
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel gradient inelastic beam theory and a corresponding flexibility-based (FB) frame element formulation to treat major weaknesses of existing FB formulations in the presence of softening section ...
Enhanced Rayleigh Damping Model for Dynamic Analysis of Inelastic Structures
Publisher: ASCE
Abstract: This paper presents an Enhanced Rayleigh damping model for dynamic analysis of inelastic structures. The conventional Rayleigh damping model has been extensively used to represent inherent energy dissipation sources in ...
Numerical Simulation of Hybrid Sliding-Rocking Columns Subjected to Earthquake Excitation
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel element formulation for the dynamic analysis of bridges incorporating posttensioned segmental columns with hybrid sliding-rocking (HSR) joints distributed over their height. These columns are ...
Seismic Repair Assessment of Hybrid Sliding–Rocking Bridge Columns through Integrated Experimentation and Expert Panel Solicitation
Publisher: ASCE
Abstract: Due to the large number of bridges that will need upgrade, retrofit, or replacement in coming years, there is an increasing need for seismic bridge design techniques that are compatible with accelerated bridge construction ...
Multinode Gradient Inelastic Force-Based Beam-Column Element Formulation
Publisher: ASCE
Abstract: In the presence of softening section constitutive relations, classical beam theories predict erroneous strain singularities, and the corresponding force/flexibility-based (FB) beam-column element formulations result in ...
Effect of Major Design Parameters on the Seismic Performance of Bridges with Hybrid Sliding–Rocking Columns
Publisher: ASCE
Abstract: This paper explores the effects of major design variables on the seismic performance of the so-called hybrid sliding–rocking (HSR) bridge columns. The HSR bridge columns are precast concrete segmental columns with internal ...
Experimental Assessment of Second-Generation Hybrid Sliding-Rocking Bridge Columns under Reversed Lateral Loading for Free and Fixed End Rotation Conditions
Publisher: ASCE
Abstract: Hybrid sliding-rocking (HSR) bridge columns are among the resilient column designs recently developed to allow accelerated bridge construction for bridge substructures in seismic areas. HSR columns are precast concrete ...
