Effect of Total Stress Path and Gas Volume Change on Undrained Shear Strength of Gassy Clay
Publisher: ASCE
Abstract: Clay with free gas bubbles can be frequently encountered in the seabed. Gassy clay is an unsaturated soil, but its mechanical behavior cannot be described using conventional unsaturated soil mechanics because it has a ...
Fault-Tolerant Model-Free Predictive Control of Spacecraft Coupled Rotational–Translational Relative Motion
Publisher: ASCE
Abstract: The problem of controlling coupled six-degrees-of-freedom (6-DOF) relative motion of an integrated-actuation spacecraft in the presence of actuator faults, and especially failures, is investigated in this paper. Considering ...
Vertical Vibration of Multiple Flexible Strip Foundations on Multilayered Transversely Isotropic Poroelastic Soils
Publisher: ASCE
Abstract: In this paper, vertical vibrations of a group of flexible strip foundations on multilayered transversely isotropic poroelastic soils are presented. The dynamic interaction problem is studied by employing a variational ...
Three-Dimensional Face Stability Analysis of Deep and Shallow Tunnels in Rock Masses
Publisher: ASCE
Abstract: Face stability is a critical issue in the stability analysis of tunnels, especially in soft soils and crushed rock masses. In this paper, considering two three-dimensional collapse mechanisms, upper-bound solutions are ...
Stability Assessments of Reinforced Tunnel Face Using Improved Homogenization Approach
Publisher: ASCE
Abstract: In this work, the stability of a reinforced tunnel face is examined by combining the homogenization method with the kinematic approach of limit analysis. A three-dimensional (3D) heterogeneous and anisotropic failure ...
Time Series Data Decomposition-Based Anomaly Detection and Evaluation Framework for Operational Management of Smart Water Grid
Publisher: ASCE
Abstract: With the increasing adoption of advanced meter infrastructure (AMI), smarter sensors, and temporary and/or permanent data loggers, it is imperative to leverage data analytics methods with hydraulic modeling to improve the ...
Slender RC Columns Strengthened with a Novel Hybrid Strengthening System of External Longitudinal and Transverse FRPs
Publisher: ASCE
Abstract: In this study, the performance of slender circular concrete columns strengthened with a novel hybrid system of longitudinally bonded prefabricated fiber-reinforced polymer (FRP) laminates and transverse FRP wrapping is ...
Structural Crack Detection from Benchmark Data Sets Using Pruned Fully Convolutional Networks
Publisher: ASCE
Abstract: Crack inspection is a crucial but labor-intensive work of maintenance for in-service bridges. Recently, the development of fully convolutional network (FCN) provides pixel-wise semantic segmentation, which is promising as ...
Fatigue Performance of Bird-Beak SHS Gap K-Joints under Brace In-Plane Force
Publisher: ASCE
Abstract: This paper presents a test campaign concerning the fatigue behavior of the bird-beak square hollow section (SHS) gap K-joints subjected to brace in-plane force. A total of four bird-beak SHS gap K-joint specimens were ...
Softened Strut-and-Tie Model for Shear and Flexural Strengths of Reinforced Concrete Pile Caps
Publisher: ASCE
Abstract: Reinforced concrete pile caps are important structural elements transmitting vertical loads from the structure to the ground. The performance of pile caps is complex, with a wide range of structural parameters in play, ...
