RISVertical Clearance Assessment for Highway Bridges Based on Multisensor Fusion Simultaneous Localization and Mapping
Publisher: ASCE
Abstract: The three-dimensional (3D) reconstruction method based on computer vision technology greatly facilitates the automated performance inspection and assessment of transportation infrastructure, in which the acquisition of ...
Improved Hybrid Denoising Method for Dynamic Monitoring of a Super-High-Rise Building Based on a GNSS-RTK Technique
Publisher: American Society of Civil Engineers
Abstract: To enhance the accuracy of dynamic monitoring based on the global navigation satellite system real-time kinematic (GNSS-RTK) technique, an improved hybrid denoising method was proposed in this study. The improved hybrid ...
Resource Leveling in Projects with Stochastic Minimum Time Lags
Publisher: American Society of Civil Engineers
Abstract: In project management, resources and time are two critical aspects influencing the success of a project. On the one hand, resource leveling, an effective resource optimization technique, is widely adopted to guarantee the ...
Computational Evaluation of Effects of Fiber Shape on Transverse Properties of Polymer Composites Considering Voids under Dynamic Loading
Publisher: American Society of Civil Engineers
Abstract: Mechanical properties of composites are dependent on the constituents’ properties and microstructure. To numerically reveal the effects of fiber shape on the transverse dynamic properties of polymer composites, unit cell ...
Effect of Shield-Tunnel Excavation on Adjacent-Pile Foundation Based on Modified Cam-Clay Model
Publisher: ASCE
Abstract: To ensure the safety of shield tunneling near pile foundation and reduce the disturbance of this phenomenon in an urban metro in the loess area of China, a three-dimensional finite-element analysis model of shield-tunneling ...
Dynamic Characteristics and Responses of Damped Outrigger Tall Buildings Using Negative Stiffness
Publisher: ASCE
Abstract: By introducing negative stiffness devices, this study further improves the maximum achievable damping ratio of conventional damped outrigger (CDO) structures with flexible perimeter columns. Dynamic characteristics of tall ...
Application of PIV Technique in Model Test of Frost Heave of Unsaturated Soil
Publisher: ASCE
Abstract: Frost heave of soil is a highly nonuniform problem, in which the local deformation is much more severe and meaningful compared with the overall deformation. When soil is upon freezing, a water–ice phase change occurs and ...
Multiperspective Evaluation Model for the Spatial Distribution of Public Service Facilities Based on Service Capability and Subjective Preferences
Publisher: ASCE
Abstract: Optimizing the spatial distribution of public service facilities (PSF) is important to promote the quality of life and the equitable distribution of public services. The spatial distribution of PSF is not only related to ...
Weibull Distribution-Based Neural Network for Stochastic Capacity Estimation
Publisher: ASCE
Abstract: Capacity is an important traffic parameter, extending nonnegligible influence on road network planning, traffic management, and traffic state prediction. The stochasticity of capacity is widely accepted considering the ...
Differences between Time-Dependent Instantaneous and Apparent Chloride Diffusion Coefficients of Concrete in Tidal Environment
Publisher: ASCE
Abstract: Time-dependent chloride diffusivity can reflect the chloride transport in concrete, which is greatly affected by different factors such as material composition and environment condition. In this paper, three tests with ...
