RISEarth Pressure due to Vibratory Compaction
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental data on the variation of lateral earth pressure against a nonyielding retaining wall due to soil filling and vibratory compaction. Air-dry Ottawa sand was placed in five lifts and each lift ...
Closure to “Passive Earth Pressure with Critical State Concept” by Yung-Show Fang, Ying-Chieh Ho, and Tsang-Jiang Chen

Passive Earth Pressure with Critical State Concept
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental data of earth pressure acting against a vertical rigid wall, which moved toward a mass of dry sand. The backfill had been placed in lifts to achieve relative densities of 38, 63, and 80%. ...
Passive Earth Pressures with Various Wall Movements
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental data of earth pressure acting against a vertical rigid wall, which moved into a mass of dry sand with a stress‐free horizontal surface under various wall‐movement modes. To investigate the ...
Surrogate-Based Time-Dependent Reliability Analysis for a Digital Twin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mature digital twin (DT) is supposed to enable engineers to accurately evaluate the real-time reliability of a complex engineering system. However, in practical engineering problems, reliability analysis (RA) often ...
Tribological Behaviors of PTFE-Based Composites Filled With Nanoscale Lamellar Structure Expanded Graphite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a polytetrafluoroethylene (PTFE)/nano-EG solid self-lubricating composite that exhibits very low friction coefficient and wear rate. In present study, the influences of the ...
Shake-Table Test for a Typical Curved Bridge: Wave Passage and Local Site Effects
Publisher: American Society of Civil Engineers
Abstract: To study the effects of ground motion spatial variations on curved bridges, this paper presents a shake-table test for a 1/10-scale typical curved bridge under spatial ground motions, including wave passage effect, local ...
Surrogate Modeling of Nonlinear Dynamic Systems: A Comparative Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surrogate models play a vital role in overcoming the computational challenge in designing and analyzing nonlinear dynamic systems, especially in the presence of uncertainty. This paper presents a comparative study of ...
Exploit Social Distancing in Construction Scheduling: Visualize and Optimize Space–Time–Workforce Tradeoff
Publisher: ASCE
Abstract: The COVID pandemic has given rise to the necessity of social distancing regulations, which has brought the importance of workspace management on the construction site to an unprecedented level. Understanding and visualizing ...
Automatic Pixel-Level Segmentation of Multiple Pavement Distresses and Surface Design Features with PDSNet II
Publisher: American Society of Civil Engineers
Abstract: Effective distress detection and quantitative analysis play a crucial role in road maintenance and driving safety. The Pavement distress segmentation network (PDSNet) is designed to combine the pyramid scene parsing network ...
