Seismically Resilient Hybrid Precast Concrete Piers with Ultrahigh-Performance Concrete
Publisher: ASCE
Abstract: This paper investigated a novel hybrid precast pier system that utilized ultrahigh-performance concrete (UHPC). The pier combines features of emulative and nonemulative (of cast-in-place construction) systems to balance ...
Numerical Investigation of High-Strength Steel and Ultrahigh-Performance Concrete for Ductile Rectangular Hollow Columns
Publisher: ASCE
Abstract: Ultrahigh-performance concrete (UHPC) has the potential to address seismic performance issues reported for rectangular hollow columns. However, an impediment to the use of UHPC is its limited flexural ductility compared ...
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’ ...
Shear Condition Classification of Cracked Reinforced Concrete Beams Using Machine Learning
Publisher: American Society of Civil Engineers
Abstract: RC bridges represent about 40% of the US bridge inventory, with many of these bridges reaching or surpassing their design service life. As a result, there is a significant number of structures that require fast and accurate ...
Sources of Crack Growth in Pretensioned Concrete-Bridge Girder Anchorage Zones after Detensioning
Publisher: American Society of Civil Engineers
Abstract: As a result of heavy prestressing, anchorage zones of bridge girders frequently crack in consistent patterns at prestress transfer and cause durability concerns. These cracks, which appear during prestress release, continue ...
Tessellated Structural-Architectural Systems: Concept for Efficient Construction, Repair, and Disassembly
Publisher: ASCE
Abstract: This paper introduces a tessellated structural-architectural (TeSA) wall system concept with the potential for improving both resilience and sustainability of the built environment. Resilience requires fast recovery and ...
