Reinforced-Concrete Shear Walls Retrofitted Using Weakening and Self-Centering: Numerical Modeling
Publisher: ASCE
Abstract: This paper investigates a novel retrofit strategy for code-deficient reinforced-concrete (RC) shear walls that are vulnerable to undesirable failure modes. The strategy combines weakening by partially cutting the wall base ...
Experimental Investigation of Surface Preparation on Normal and Ultrahigh-Performance Concrete Interface Behavior
Publisher: ASCE
Abstract: Many bridges in the United States are classified as structurally deficient and many others are nearing the end of their design service life, necessitating robust and durable bridge rehabilitation methodologies. States’ ...
Experimental Investigation and Finite-Element Modeling of an Aluminum Energy Dissipater for Cross-Laminated Timber Walls under Reverse Cyclic Loading
Publisher: ASCE
Abstract: Cross-laminated timber (CLT) panels with unbonded post-tensioning and a rocking mechanism can be used as a robust lateral load–resisting system (LLRS). The seismic performance of these systems can be improved further by ...
Bridge Decks with Precast UHPC Waffle Panels: A Field Evaluation and Design Optimization
Publisher: American Society of Civil Engineers
Abstract: The first full-depth precast ultrahigh-performance concrete (UHPC) waffle panels have been designed and implemented in a bridge replacement project to use accelerated bridge construction and increase bridge deck longevity. ...

Concept and Finite-Element Modeling of New Steel Shear Connectors for Self-Centering Wall Systems
Publisher: American Society of Civil Engineers
Abstract: Self-centering precast concrete walls have been found to provide excellent seismic resistance. Such systems typically exhibit low energy dissipation, requiring supplementary dissipating components to improve their seismic ...
Cyclic Response of Reinforced Concrete Walls with Different Anchorage Details: Experimental Investigation
Publisher: American Society of Civil Engineers
Abstract: Previous tests of structural walls have routinely used continuous reinforcement extending from the foundation to the top of the specimen. This detailing is consistently different from that of multistory walls in the field, ...
