RISPhysics-Informed Neural Networks for System Identification of Structural Systems with a Multiphysics Damping Model
Publisher: ASCE
Abstract: Structural system identification is critical in resilience assessments and structural health monitoring, especially following natural hazards. Among the nonlinear structural behaviors, structural damping is a complex ...
Estimation Method of Intersection Signal Cycle Based on Empirical Data
Publisher: ASCE
Abstract: The signal cycle plays an important role in the design of timing optimization and evaluation for a signal intersection. However, in some cities, there is a lack of unified management of intelligent transportation system, ...
Automated Bridge Crack Detection Based on Improving Encoder–Decoder Network and Strip Pooling
Publisher: American Society of Civil Engineers
Abstract: The detection of bridge cracks is an important task in bridge maintenance. It can also reflect the health of the bridge. However, cracks are usually in the form of strips, which are different from the concrete surface. ...
Fixture Kinematic Analysis Based on the Full Contact Model of Rigid Bodies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conventional point-kinematic model of fixtures has only treated point geometry of the contacts between locators and workpiece. However, this model, which ignores the underlying surface properties ...
Comparison of Durability and Mechanism between Sprayed Concrete and Ordinary Concrete at Different Erosion Age
Publisher: ASCE
Abstract: The differences in corrosion between the erosion mechanisms of sprayed concrete (SpC) and ordinary concrete (OC) under sulfate attack at different corrosion ages were investigated in this paper. Here, 10% sodium sulfate ...
Optimal Independent Baseline Searching for Global GNSS Networks
Publisher: ASCE
Abstract: An n-station continuously operated global navigation satellite system (GNSS) network contains n-1 independent baselines. Baseline structure is critical to positioning accuracy, and the final result is dependent on the ...
Capacity Change of Piles in Loess under Cyclic Axial Tension or Compression Load
Publisher: ASCE
Abstract: This study examines the capacity of single piles subjected to cyclic axial tension or compression load in the loess area under in situ compaction degree and extruding conditions. Four cyclic tension and compression loading ...
Vertical Earth Pressure for a High-Filled Cut-and-Cover Tunnel: Site Measurements and DEM Simulations
Publisher: ASCE
Abstract: Determining vertical earth pressure (VEP) is crucial in designing high-filled cut-and-cover tunnel (CCT) structures. This parameter directly influences the safety and economy of the structure. However, the current pressure ...
Compressive Deformation Characteristics of Sintered Loess after Being Saturated with Water
Publisher: American Society of Civil Engineers
Abstract: Addressing the challenges of wet and soft loess foundations is crucial in geotechnical engineering due to their inherent low strength and high compressibility. High-temperature sintering technology is a leading method for ...
Prediction for Rock Conditions in a Tunnel Area Using Advanced Geological Drilling Predictions Based on Multiwavelet Analysis and Modified Evidence Reasoning
Publisher: ASCE
Abstract: Advanced geological prediction plays an essential role in disaster prevention and safety guarantee. In this paper, by combining multiwavelet analysis with modified evidence reasoning, a new geological prediction method for ...
