RISNumerical Simulation of Rock Fracture and Permeability Characteristics under Stress–Seepage–Damage Coupling Action
Publisher: American Society of Civil Engineers
Abstract: In the field of rock mechanics, the stress–seepage–damage coupling numerical simulation of rock has always been a hot topic but a difficult problem. Based on this background, we newly derive the smoothed particle hydrodynamics ...
Exploring Observed and Unobserved Preference Heterogeneity in Choice Behavior of Demand Responsive Customized Bus Service
Publisher: ASCE
Abstract: The users' taste preferences for the demand responsive customized bus (DRCB) and, in particular, the its mechanism of heterogeneity, which determine routing, timetabling, and even launch and cancellation of the DRCB service, ...
Centrifuge Modeling of an Embankment Resting on Liquefiable Ground: Investigation of the Effects of a Low Amount of Nonplastic Fines
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study on the effects of low amounts of nonplastic fines on the behavior of an embankment resting on liquefiable ground through centrifuge modeling. In the dynamic centrifuge tests, a ...
Estimation of Organ Transport Function: Model-Free Deconvolution by Recursive Quadratic Programming Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model-free deconvolution method is proposed for evaluating the frequency distribution function of organ transit times. The deconvolution is treated as a nonlinear constrained optimization problem ...
Experimental and Analytical Lateral Performance of Posttensioned CLT Shear Walls and Conventional CLT Shear Walls
Publisher: ASCE
Abstract: Cross-laminated timber (CLT) is suitable for shear walls owing to its high in-plane stiffness. However, according to a series of shaking table tests on multistory CLT structures, premature connection damage always occurs ...
Comparative Studies on Structures with a Tuned Mass Damper and a Particle Damper
Publisher: American Society of Civil Engineers
Abstract: In recent years, much attention has been paid to the research and development of a new kind of passive control device named a particle damper, which has a very similar configuration and application method to the tuned mass ...
A Robust Model for Hydrogen Supply Chain Network Design in China Under Renewable Energy Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The increasing demand for new energy sources in China, coupled with the abundant waste, has prompted the exploration of converting excess renewable energy into hydrogen through electrolyzers. However, the uncertainty ...
Potential Loss in Prestressing Tendon Forces under Long-Term Service Conditions: Cross-Laminated Timber Shear Wall Applications
Publisher: ASCE
Abstract: The seismic performance of post-tensioned cross-laminated timber (CLT) shear walls depends on the existing prestressing tendon force. The prestressing force will change over time because of the time-dependent elastic, ...
Analytical Investigations on the Glulam Beam-to-Column Connections Reinforced with Knee Braces
Publisher: ASCE
Abstract: The glulam knee-braced frame structure is a type of the post-and-beam construction and has extensive application in real projects. The mechanical performance of the beam-to-column connection reinforced with knee brace has ...
Experimental Testing and Analytical Modeling of Glulam Moment Connections with Self-Drilling Dowels
Publisher: ASCE
Abstract: An experimental and analytical study on rotational behavior of glulam beam-column moment connections with self-drilling dowels (SDDs) is conducted. Connection properties including strength, stiffness, ductility, and energy ...
