RISPerformance of Elliptical Hollow Sections under Combined Compression and Cyclic Bending
Publisher: American Society of Civil Engineers
Abstract: This paper comprehensively discusses the potential of applying elliptical hollow sections (EHSs) for seismic regions. The study commenced with an experimental investigation of 12 EHS beam-column specimens under combined ...
Constitutive Modeling of Kinematic Hardening Behavior of Saturated Anisotropic Soils
Publisher: American Society of Civil Engineers
Abstract: A new three-dimensional cone-cap limit-state surface (LSS) model is proposed for cross-anisotropic, saturated, cohesionless, or cohesive remolded soils in consideration of anisotropic yielding and kinematic hardening. ...
Intelligent Approach Based on Random Forest for Safety Risk Prediction of Deep Foundation Pit in Subway Stations
Publisher: American Society of Civil Engineers
Abstract: The number of safety accidents caused by excavation of deep foundation pits in subway stations has been increasing rapidly in recent years. Thus, precisely predicting the safety risks for subway deep foundation pits bears ...
Behavior of Amorphous Peaty Soil under Long-Term Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: A series of one-way and long-term (1, cycles) cyclic triaxial tests was carried out to investigate the cyclic behavior of peaty soil from Kunming, China. The organic components of the peaty soil were generally highly ...
Genetic Algorithm–Based Multiobjective Optimization for 3D Printable Design of a Double-Shell Lunar Habitat Structure
Publisher: ASCE
Abstract: The establishment of lunar habitats is significant for humans to explore the Moon and carry out scientific work. Constructing lunar habitats through additive manufacturing using lunar in situ resource is a promising solution. ...
A Binary-Medium Constitutive Model for Artificially Structured Soils Based on the Disturbed State Concept and Homogenization Theory
Publisher: American Society of Civil Engineers
Abstract: Triaxial compression tests were carried out on artificially structured soil samples at confining pressures of 25, 37.5, 50, 100, 200, and 400 kPa. A binary-medium constitutive model for artificially structured soils is ...
Elastic Anisotropic Viscoplastic Modeling of the Strain-Rate-Dependent Stress–Strain Behavior of K0 -Consolidated Natural Marine Clays in Triaxial Shear Tests
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new three-dimensional (3D) anisotropic elastic viscoplastic (EVP) model for the time-dependent stress–strain behavior of
Experimental Investigation on Piezoresistive Properties and Acoustic Emission Characteristics of Carbon Fiber–Based Gangue Concrete
Publisher: ASCE
Abstract: Concrete with coal gangue as aggregate has a self-sensing ability with addition of carbon fiber (CF), which has an outstanding effect in terms of dealing with the large amount of coal gangue discharge and monitoring the ...
Hybrid Support Vector Machine Optimization Model for Prediction of Energy Consumption of Cutter Head Drives in Shield Tunneling
Publisher: American Society of Civil Engineers
Abstract: The energy consumption of cutter head drives accounts for over half of their total power capacity, and it can reach several thousand kilowatts in shield machines. The analysis of the energy consumption of cutter head drives ...
