RISCompressive Behavior of Concrete-Filled Filament-Wound FRP Tubes with Local Tube Damage
Publisher: ASCE
Abstract: Concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) are an emerging and attractive form of column for new constructions. Such a column consists of outer filament-wound FRP tubes that are filled with plain or ...
Strength and Dilatancy of Overconsolidated Clays in Drained True Triaxial Tests
Publisher: American Society of Civil Engineers
Abstract: The long-term mechanical behavior of overconsolidated (OC) clays in three-dimensional (3D) stress states plays an important role in many geotechnical problems, such as slope failures. However, previous experimental studies ...
Stress–Strain Behavior of FRP-Confined Recycled Aggregate Concrete in Square Columns of Different Sizes
Publisher: ASCE
Abstract: The application of recycled aggregate concrete (RAC) has so far mainly been limited to nonstructural components because of its inferior short- and long-term performance compared with normal concrete. Encasement of RAC with ...
Compressive Behavior of FRP–UHPC/ECC–Steel Double-Skin Tubular Columns under Eccentric Loading
Publisher: American Society of Civil Engineers
Abstract: Hybrid double-skin tubular columns (DSTCs), which consist of an outer fiber-reinforced polymer (FRP) tube, an inner steel tube, and a concrete annular layer between the two tubes, possess many advantages, such as high load ...
Key Construction Technologies for Large River-Crossing Slurry Shield Tunnel: Case Study
Publisher: ASCE
Abstract: With the rapid urbanization and unprecedented development of urban traffic, there is an increasing need for river crossings with large-diameter tunnels in short spans, such as in the Yangtze River Delta, China. In order ...
Behavior of Different-Sized FRP-Confined Square Compound Concrete Columns Containing Recycled Concrete Lumps
Publisher: ASCE
Abstract: A new concrete recycling method is to crush demolished concrete into distinctly large recycled concrete lumps (RCLs), which are in a direct mix with fresh concrete, leading to the so-called compound concrete. Not only can ...
Unified Description of Thermoelastoplastic Behavior of Geomaterials Considering Interparticle Bonding
Publisher: ASCE
Abstract: In this paper, a thermoelastoplastic constitutive model integrating interparticle bonding is proposed to describe the fundamental thermal and mechanical behaviors for different geomaterials (e.g., soft rock, sand, and clay) ...
Durability Assessment of Hybrid Double-Skin Tubular Columns under Wet–Dry Cyclic Environments
Publisher: American Society of Civil Engineers
Abstract: Hybrid fiber-reinforced polymer (FRP)–concrete–steel hybrid double-skin tubular columns (DSTCs) consist of an outer FRP tube, an inner steel tube, and a layer of concrete filled between the two tubes. Previous studies have ...
Effects of Overconsolidation and Structural Behaviors of Shanghai Clay on Deformation Caused by Deep Excavation
Publisher: American Society of Civil Engineers
Abstract: Shanghai clay exhibits overconsolidation, soil structural, and small-strain characteristics. While there have been several studies on the effects of small-strain characteristics on the deformation caused by deep excavation, ...
Structural Behavior of Hybrid FRP–Concrete–Steel Double-Skin Tubular Arches: Experiments and Numerical Modeling
Publisher: American Society of Civil Engineers
Abstract: Hybrid fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular members (DSTMs) yield much higher strength-to-weight ratios and much better corrosion resistance than traditional reinforced concrete members. The ...
