RISInfluence of Rock Depth on Seismic Site Classification for Shallow Bedrock Regions
Publisher: American Society of Civil Engineers
Abstract: Seismic site classifications are used to represent site effects for estimating hazard parameters (response spectral ordinates) at the soil surface. Seismic site classifications have generally been carried out using average ...
Properties and Application of Sea Sand in Sea Sand–Seawater Concrete
Publisher: ASCE
Abstract: Contradictory results have been published on the effect of sea sand and seawater in concrete as opposed to conventional river sand and freshwater. The majority of studies show equivalent, if not better, results when sea ...
Experimental Investigation on the Behavior of Hollow-Core Glass Fiber-Reinforced Concrete Columns with GFRP Bars
Publisher: ASCE
Abstract: Steel reinforcing bars, helices, and fibers in concrete columns are susceptible to corrosion, particularly in aggressive environments. This study experimentally investigated the use of corrosion-free glass fiber-reinforced ...
Cyclic Performance of GFRP-RC T-Connections with Different Anchorage and Connection Details
Publisher: ASCE
Abstract: This study investigated the effects of different configurations of connection reinforcement and anchorages on the cyclic behavior of glass fiber–reinforced polymer (GFRP) reinforced-concrete (RC) exterior beam–column ...
Investigation of the Effectiveness of CFRP Strip Ties as Transverse Reinforcement for GFRP Bar–Reinforced Concrete Columns
Publisher: ASCE
Abstract: This paper investigates the effectiveness of carbon fiber–reinforced polymer strips ties (CST) as the transverse reinforcement for normal strength glass fiber–reinforced polymer reinforced concrete (GFRP-RC) square columns. ...
Behavior of Sand–Tire Chip Mixtures in Constant Shear Drained Stress Path
Publisher: ASCE
Abstract: This paper presents the potential of scrap tire in controlling the onset of instability of sand in the constant shear drained (CSD) stress path. A series of triaxial tests in the constant shear drained stress path was ...
Improvement in Bond Strength of Steel Bar in Geopolymer Concrete by Adding Graphene Nanoplatelets
Publisher: American Society of Civil Engineers
Abstract: The bond strength of steel reinforcement bars in concrete is of prime importance for the strength and serviceability of reinforced concrete structures. The composition of concrete directly affects the bond strength of steel ...
Effect of the Viscosity of Alkali Activators on the Particle Packing of Geopolymer Mortar
Publisher: American Society of Civil Engineers
Abstract: The packing behavior of a particle system is significantly influenced by the particle size distribution (PSD) of the mix and the viscosity of the liquid. In this study, the effect of the viscosity of the commonly used ...
Development of Sustainable Fiber-Reinforced Ambient-Cured SCGC with Enhanced Mechanical and Microstructural Properties for Infrastructure Applications
Publisher: American Society of Civil Engineers
Abstract: AbstractSelf-compacting geopolymer concrete (SCGC) has been recognized as a sustainable alternative
to conventional cement-based materials. The SCGC includes the convenience of self-compacting
concrete (SCC) with the ...
