RISActive Earth Pressure of Finite Width Soil Considering Intermediate Principal Stress and Soil Arching Effects
Publisher: ASCE
Abstract: Traditional earth pressure theories are based on the assumption of semi-infinite space. The existence of intermediate principal stress and soil arching effects is ignored, which will cause significant errors in the application ...
Modeling of Cross-Coupling Responses on Hingeless Helicopters via Gyroscopic Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The perplexing cross-coupled responses between the control axes on hingeless helicopters have puzzled researchers for years. Unlike previous studies, which introduced a physically meaningless phase-lag ...
Damage Constitutive Model of Fly Ash Concrete under Freeze-Thaw Cycles
Publisher: American Society of Civil Engineers
Abstract: The mechanical deterioration of concrete exposed to freeze-thaw cycles is one of the most important durability problems under subzero temperature conditions. At present, studies on concrete behavior under freeze-thaw cycles ...
Implementation of a Triaxial Dynamic Modulus Master Curve in Finite-Element Modeling of Asphalt Pavements
Publisher: American Society of Civil Engineers
Abstract: The newly developed Mechanistic-Empirical Pavement Design Guide (MEPDG) uses the dynamic modulus master curve to account for the temperature and frequency dependent behavior of asphalt concrete. However, the master curve ...
Spatial Estimation of Material Parameters and Refined Finite-Element Analysis of Rockfill Dam Based on Construction Digitization
Publisher: American Society of Civil Engineers
Abstract: Quality levels for rockfill dam compaction (herein, porosity is an important index for assessing dam-material compaction quality) in any location can be estimated based on construction digitization technologies. According ...
Performance Evaluation of Lime Mortars with Metakaolin and CMC for Restoration Application
Publisher: ASCE
Abstract: The degradation of ancient buildings has attracted much attention, and plane lime mortar cannot meet the requirements of utilization in special environmental loads or buildings. In order to improve the hydraulic properties ...
Energy Characteristics and Damage Constitutive Model of Frozen Sandstone under Triaxial Compression
Publisher: ASCE
Abstract: To study the energy characteristics and damage laws of frozen rock during mine freezing, a triaxial compression test and synchronous acoustic emission test of frozen sandstone are conducted. The results show that (1) the ...
Multiparameter Sensitivity Analysis of Flexural–Tensile Property of Basalt Fiber–Reinforced Asphalt Mixture
Publisher: ASCE
Abstract: To evaluate the sensitivity of basalt fiber content, length-diameter ratio, and modulus to the flexural–tensile properties of fiber-reinforced asphalt mixture, the spatial random distribution of basalt fibers was realized ...
Characterization of Linear Viscoelastic Behavior of Asphalt Concrete Using Complex Modulus Model
Publisher: American Society of Civil Engineers
Abstract: A new approach for the characterization of linear viscoelastic (LVE) behavior of asphalt concrete is presented in this study. The proposed approach uses the associated function of the original Havriliak-Negami (HN) formulation ...
Multiscale Method for Geometrical Nonlinear Analysis of Fluid Actuated Cellular Structures with Arbitrary Polygonal Microstructures
Publisher: American Society of Civil Engineers
Abstract: Fluid actuated cellular structures are morphing structures inspired by the nastic movement of plants. These materials have a wide array of applications from morphing aircraft wings to soft robotics. The nonlinear shape-morphing ...
