RISStochastic Modeling of Reinforced Concrete Cracking due to Nonuniform Corrosion: FEM-Based Cross-Scale Analysis
Publisher: American Society of Civil Engineers
Abstract: Chloride-induced rebar corrosion is one primary cause of early cracking of reinforced concrete (RC). A model to accurately predict the time before steel corrosion and concrete cracking, with due consideration of the ...
Impact of Urban Agglomeration Development Planning Policy on the Promotion of Efficiency of Urban Economic Development: Empirical Evidence from 283 Cities in China
Publisher: American Society of Civil Engineers
Abstract: Urban agglomeration development planning policy (referred to as planning policy in this paper) played a significant role in promoting regional economic development. However, an important issue is whether this planning ...
An Experimental Investigation of Yield Surfaces and Loading Surfaces of Pure Aluminum With Stress-Controlled and Strain-Controlled Paths of Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tension-torsion tests with a computer controlled servohydraulic testing machine are reported. Yield surfaces were obtained during a load controlled path, which includes combined stress creep, as ...
Bridging the Gap between Random Microstructure and 3D Meshing
Publisher: American Society of Civil Engineers
Abstract: There are different ways to mathematically represent three-dimensional (3D) heterogeneous material microstructures. It is desirable to pick the representation that best bridges the gap between heterogeneous microstructure ...
Temperature Related Visco-Elastoplastic Properties of Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Parameter characterization of asphalt mixtures at various test temperatures is a crux to the performance evaluation of flexible pavements using the visco-elastoplastic method. But the difficulty of determining the relevant ...
Improved Model for Three-Dimensional Virtual Concrete: Anm Model
Publisher: American Society of Civil Engineers
Abstract: Construction aggregate particles, fine or coarse, can be scanned by X-ray computed tomography and mathematically characterized using spherical harmonic series, and can then be used to simulate random parking of irregular ...

Interval Optimization for Signal Timings with Time-Dependent Uncertain Arrivals
Publisher: American Society of Civil Engineers
Abstract: Contending with excessive delays at signalized intersections due to traffic flow fluctuation has been recognized as one of the most challenging issues for traffic researchers and engineers. Due to the uncertainty of vehicle ...
Experimental Study of Seismic Behavior of High-Strength RC Columns Strengthened with CFRP Subjected to Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: Eight high-strength RC columns confined by carbon fiber–reinforced polymer (CFRP) sheets and two control specimens are tested under cyclic lateral load and constant axial load. The effectiveness of the high-strength RC ...
Real-Time Thermal Imaging-Based System for Asphalt Pavement Surface Distress Inspection and 3D Crack Profiling
Publisher: ASCE
Abstract: Infrared thermography is a cost-effective nonintrusive testing approach to assess surface and near-surface distresses, such as asphalt pavement surface cracks. However, the raw data collected by thermal cameras cannot be ...
