RISQuasi-Static Testing of Posttensioned Nonemulative Column-Footing Connections for Bridge Piers
Publisher: American Society of Civil Engineers
Abstract: Accelerated bridge construction (ABC) is gaining popularity because it offers a number of advantages over conventional methods of construction. Prefabrication of bridge components for rapid on-site assembly is a highly ...
Characterization of Filler-Free Buckling Restrained Fuse-Type Energy Dissipation Device for Seismic Applications
Publisher: ASCE
Abstract: The grooved-type dissipater is an axial, metal hysteretic dissipative device. It is an alternative to the epoxy- or grout-filled buckling restrained fuse (BRF)-type dissipater. This device consists of a mild steel rod which ...
Low-Damage Seismic Design for Accelerated Bridge Construction
Publisher: American Society of Civil Engineers
Abstract: In this research, a low-damage seismic design technology has been proposed for accelerated bridge construction (ABC). ABC low damage aims to minimize, and potentially eliminate, damage in a precast bridge during an earthquake. ...
Monitoring Dynamic Properties of a Pres-Lam Structure: Trimble Navigation Office
Publisher: ASCE
Abstract: Pres-Lam technology relies on unbonded post-tensioning tendons to provide moment capacity to timber beam-column, wall-foundation, or column-foundation connections. When designing buildings for high-seismic-risk areas, ...
Quasi-Static Cyclic Testing of Hybrid Posttensioned Bridge Column Supported on a Monopile Foundation
Publisher: ASCE
Abstract: In this research, a low-damage posttensioned rocking solution referred to as dissipative controlled rocking (DCR) connection is proposed for bridge columns supported on monopile foundations. The DCR connection is a low-damage ...
Effects of Corrosion on Stress–Strain Behavior of Confined Concrete
Publisher: ASCE
Abstract: An analytical model is proposed to predict the stress–strain relationship of confined concrete subjected to reinforcement corrosion. The stress–strain graph of confined concrete with corroded reinforcement was predicted ...
Finite-Element Validation of U-Shaped Flexural Plates Integrated into a Novel Brace Dissipator
Publisher: American Society of Civil Engineers
Abstract: Metallic dissipators have gained considerable attention in the seismic structural design industry in recent years because of their ability to provide stable hysteresis behavior and excellent energy dissipation capacity. ...
Impact of Artificial Corrosion Technique under Variable Acceleration on Morphological Efficacy in Reinforced Concrete Elements
Publisher: American Society of Civil Engineers
Abstract: The popularity of artificially accelerated methodologies for inducing corrosion in reinforced concrete (RC) elements has increased exponentially over recent decades due to their ability to achieve broad damage spectra ...
Development and Testing of an Alternative Dissipative Posttensioned Rocking Timber Wall with Boundary Columns
Publisher: American Society of Civil Engineers
Quasi-Static Cyclic Testing of Two-Thirds Scale Unbonded Posttensioned Rocking Dissipative Timber Walls
Publisher: American Society of Civil Engineers
Abstract: Posttensioning low-damage technologies were first developed in the late 1990s as the main outcome of the U.S. Precast Seismic Structural System (PRESSS) program coordinated by the University of California, San Diego, and ...
