RISSmall-Strain Behavior of Granular Soils. I: Model for Cemented and Uncemented Sands and Gravels
Publisher: American Society of Civil Engineers
Abstract: A simple formulation is presented that predicts the nonlinear small strain behavior of cemented and uncemented granular soils. Its performance is evaluated through the comparison of model predictions to results from ...
Small-Strain Behavior of Granular Soils. II: Seismic Response Analyses and Model Evaluation
Publisher: American Society of Civil Engineers
Abstract: Using the recorded response at two vertical array sites, the SimSoil model presented in the companion paper is evaluated. The SimSoil model, which describes the small strain nonlinear behavior of granular materials, is ...
Inertia–Gravity Waves Breaking in the Middle Atmosphere at High Latitudes: Energy Transfer and Dissipation Tensor Anisotropy
Publisher: American Meteorological Society
Abstract: We present direct numerical simulations of inertia–gravity waves breaking in the middle–upper mesosphere. We consider two different altitudes, which correspond to the Reynolds number of 28 647 and 114 591 based on wavelength ...
Alignment between Lean Principles and Practices and Worker Safety Behavior
Publisher: American Society of Civil Engineers
Abstract: Alignment and synergy between the areas of lean construction and safety management are expected because all near misses and injury incidents represent waste from the lean perspective. This paper describes a research study ...
Closure to “Soil Deformation and Excess Pore Pressure Field around a Closed-Ended Pile” by Juan M. Pestana, Christopher E. Hunt, and Jonathan D. Bray
Publisher: American Society of Civil Engineers
Unified Compression Model for Venice Lagoon Natural Silts
Publisher: American Society of Civil Engineers
Abstract: Over the last 50 years, the city of Venice, Italy, has observed a significant increase in the frequency of flooding. Numerous engineering solutions have been proposed, including the use of movable gates located at the three ...
Soil Deformation and Excess Pore Pressure Field around a Closed-Ended Pile
Publisher: American Society of Civil Engineers
Abstract: Numerous field and laboratory research projects have examined loading conditions, total soil stresses, and excess pore pressures during and following pile installation. Recently, a large number of seismic retrofitting ...
Investigating the Effects of Percussion on Excavation Forces
Publisher: American Society of Civil Engineers
Abstract: Percussive excavation is researched as a viable technology to reduce the shear strength of the dry lunar soil simulant JSC-1A. Experimental tests were conducted in a percussive and quasi-static test bed, which used a replica ...
New Layer-Moduli Back-Calculation Method Based on the Constrained Extended Kalman Filter
Publisher: American Society of Civil Engineers
Abstract: In pavement engineering, good estimation of layer moduli from nondestructive methods is an important tool for scheduling and designing rehabilitation projects. The falling weight deflectometer test is perhaps the most ...
Qualification of Induction Heating Stress Improvement for Mitigation of Stress Corrosion Cracking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the efforts toward qualification of induction heating stress improvement (IHSI) for mitigation of intergranular stress corrosion cracking (IGSCC) in Boiling Water Reactor (BWR) ...
