RISNumerical Investigation of Fire-Induced Spalling of Normal Strength Concrete
Publisher: ASCE
Abstract: It is well known that fire-induced spalling usually occurs to high-strength and ultra-high performance concretes. However, experiments have shown that thermal spalling can also occur to normal strength concrete (NSC) and ...
Fracture Analysis of FRP-Plated Notched Concrete Beams Subjected to Three-Point Bending
Publisher: American Society of Civil Engineers
Abstract: Three-point bending tests of fiber-reinforced polymer (FRP) plated notched concrete beams have great potential to become a standard test method for evaluating the shear bond performance of FRP-to-concrete interfaces. This ...
Modification of the Einstein Bed-Load Formula
Publisher: American Society of Civil Engineers
Abstract: The original derivation of the Einstein bed-load formula involves several oversimplified assumptions concerning step length of a particle, exchange time, and probability of being lifted into motion. A modified version of ...

Abstract: Three-point bending tests of fiber-reinforced polymer (FRP) plated notched concrete beams have great potential to become a standard test method for evaluating the shear bond performance of FRP-to-concrete interfaces. This ...
Closed-Form Solution of the Ductility of Short FRP-Wrapped Rectangular Concrete Prisms under Eccentric Loads
Publisher: ASCE
Abstract: Confinement reinforcement, such as tubes, stirrups, and wraps, can significantly improve the strength and, more importantly, ductility of eccentrically loaded concrete prisms. However, the confinement effect in flexural ...
Improved Probabilistic Kinematic Analysis Procedure Based on Finite Size Discontinuities and Its Application to a Rock Slope at Open Pit Mine in U.S.
Publisher: American Society of Civil Engineers
Abstract: An improved probabilistic kinematic analysis procedure is suggested incorporating the six steps listed in the paper. The variability of the shear strength and discontinuity orientation is taken into account in the probabilistic ...
A Thermal-Hydraulic-Mechanical Coupling Simulation of Fluid Flow and Heat Transfer Specifically in Crossed-Rough Fractures in a Geothermal Reservoir
Publisher: ASCE
Abstract: For the development and utilization of geothermal reservoirs, a thorough understanding of fluid flow and heat transfer characteristics in rock fractures is crucial. The effect of two interacting crossed-rough fractures on ...
Regulating the Process of Microbially Induced Calcium Carbonate Precipitation through Applied Electric Fields: Evidence and Insights Using Microfluidics
Publisher: American Society of Civil Engineers
Abstract: Nonuniform cementation challenges may arise when employing microbially induced calcium carbonate precipitation (MICP) technology to treat problematic soils. Electrokinetic methods exhibit the potential to regulate the MICP ...
Axial Stress–Strain Model of LRS-FRP–Confined Rectangular Concrete Prisms Allowing for the Size Effect and Its Application in Flexural Analysis of Beams
Publisher: American Society of Civil Engineers
Abstract: Large rupture strain fiber-reinforced polymer (LRS-FRP) composites exhibit a large rupture strain exceeding 5%, thereby enhancing the ductility and strength of concrete as a confinement reinforcement with notable energy ...
Prediction of Thermal Decomposition of Hardened Cement Paste
Publisher: American Society of Civil Engineers
Abstract: When exposed to elevated temperatures, various constituents in hardened cement paste will undergo decomposition, resulting in thermal damage of concrete. To better understand the thermal damage mechanism, it is essential ...
