RISDamage Control of Composite Steel Beams Using Flexible Gel-Covered Studs
Publisher: ASCE
Abstract: This paper proposes flexible-gel-covered (FGC) studs to reduce the seismic damage of a concrete floor slab in a steel frame. Flexible gel strips intentionally release the shear constraint between the slabs and the steel ...
Test and Simulation of the Shear Resistance of the Composite Deck Using Reinforcement Frame as the Shear Connector
Publisher: ASCE
Abstract: This paper develops a novel reinforcement frame as the shear connector in the composite deck, which was expected to deliver large pre-pouring stiffness. To investigate its shear resistance, nine specimens were designed, ...
Experimental and Analytical Study of Fully Prefabricated Damage-Tolerant Beam to Column Connection for Earthquake-Resilient Frame
Publisher: American Society of Civil Engineers
Abstract: A fully prefabricated damage-tolerant beam-to-column connection is proposed as an approach toward an earthquake-resilient steel frame. By introducing a composite steel–ultrahigh-performance concrete (UHPC) joint and friction ...
Development of Fully Prefabricated Steel-UHPC Composite Deck System
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a novel fully prefabricated composite deck system to achieve green and accelerated construction in bridge engineering. Ultra-high-performance concrete (UHPC), which has excellent mechanical properties, ...
Experimental Study on Creep Failure of Non-Steam-Cured Ultrahigh-Performance Concrete under High Uniaxial Compressive Stress
Publisher: ASCE
Abstract: Ultrahigh-performance concrete (UHPC) creep failure was experimentally investigated under high uniaxial compressive stress. The influence of applied stress levels, loading times, and loading rates was considered. The failure ...
Staggered-Supported Steel Anchor Box System for Cable-Stayed Bridges
Publisher: ASCE
Abstract: This paper presents a novel anchorage structure for stay cables to reduce the load on the concrete pylon. Called the staggered-supported steel anchor box (SS-SAB), this anchorage structure provides self-balancing of the ...
Shear Resistance of Perfobond Rib Shear Connectors under Cyclic Loading
Publisher: ASCE
Abstract: Perfobond rib shear connectors (known as PBL shear connectors) are structures widely used to transfer loads between concrete and steel structural elements. The performance of PBL shear connectors under monotonic loads has ...
Quasi-Static Tests and Simulations of Round-Ended Railway Bridge Piers with a Small Shear-Span Ratio
Publisher: American Society of Civil Engineers
Abstract: This study investigates the seismic performance of round-ended railway bridge piers subjected to transverse bridge loading. Six scaled models of bridge piers with low-reinforcement ratios, low axial compression ratios, and ...
Study of Cyclic Performance and Design Method of UHPC-NSC Composite Pier
Publisher: ASCE
Abstract: The composite pier, which consists of ultra-high-performance concrete (UHPC) and normal strength concrete (NSC), is a promising option for practical engineering due to its remarkable mechanical performance. However, the ...
