RISBayesian Monte Carlo Simulation–Driven Approach for Construction Schedule Risk Inference
Publisher: ASCE
Abstract: As the construction of infrastructures becomes increasingly complex, it has often been challenged by construction delay with enormous losses. The delivery of complex infrastructures provides a rich source of data for new ...
Comparative Study on Backscattered Electron Image of Cement Paste Quantified by Frequency Histogram, Overflow and Gaussian Distribution Fitting Method
Publisher: ASCE
Abstract: Backscattered electron (BSE) images have been widely used to investigate the phases of cementitious materials. With the view of quantifying phases including pores, hydration products, and unreacted clinkers from the ...
Investigation of Corrosion Resistance and Interfacial Bonding Properties of Zn/Zn–Al Multilayer Coating/Steel Substrate System
Publisher: ASCE
Abstract: As an important mechanical property index, the interfacial bonding properties between coating and substrate are key factors in determining the corrosion resistance and reliability of the system. In this paper, the corrosion ...
Investigation of Ultrahigh-Performance Concrete Fracture Characteristics with Different Steel Fiber Fractions Based on Acoustic Emission
Publisher: ASCE
Abstract: Three-point bending test and acoustic emission (AE) monitoring of notched beams with different volume fractions of steel fiber ultrahigh-performance concrete (UHPC) were carried out. The results show that the initiation ...
Forced Convection Heat Transfer Enhancement by Porous Pin Fins in Rectangular Channels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The forced convective heat transfer in three-dimensional porous pin fin channels is numerically studied in this paper. The Forchheimer–Brinkman extended Darcy model and two-equation energy model ...
Physical Derivation of Effective Stress from Balance Law and Experimental Evidence
Publisher: American Society of Civil Engineers
Abstract: It has long been discussed whether Terzaghi’s expression for effective stress holds true for all saturated soils. To examine the physical basis of the effective stress expression, a new mechanical model is proposed. According ...
Nitrification Modeling in Pilot-Scale Chloraminated Drinking Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: A suspended growth nitrification model was developed to describe nitrification dynamics in terms of chloramine, ammonia, nitrite, nitrate, and nitrifying bacteria concentrations in pilot-scale chloraminated drinking water ...
Real-Time Optimized Trajectory Planning for a Fixed-Wing Vehicle Flying in a Dynamic Environment
Publisher: American Society of Civil Engineers
Abstract: The problem of determining an optimal feasible trajectory, for a fixed wing flying vehicle moving in a dynamical three-dimensional space, is addressed in this paper, and an analytical solution is proposed. With explicitly ...
Behavior of High-Speed Railway Ballastless Track Slabs Using Reactive Powder Concrete Materials
Publisher: American Society of Civil Engineers
Experimental Investigation on a Photovoltaic Thermal Solar System with a Linear Fresnel Lens
Publisher: American Society of Civil Engineers
Abstract: This article reports the experimental study on a concentrated photovoltaic thermal (PV/T) solar system. A nonimaging linear Fresnel lens was used as a solar concentrator to improve the density of solar energy on a PV/T ...
