RISAppropriate Wood Constitutive Law for Simulation of Nonlinear Behavior of Timber Joints
Publisher: American Society of Civil Engineers
Abstract: In structural analysis, because of its anisotropic behavior, wood requires an appropriate constitutive law covering different behavior modes, such as ductile compressive behavior and brittle character in shear and tension. ...
Mechanical Performance of Timber-to-Timber Joints with Densified Wood Dowels
Publisher: ASCE
Abstract: The wooden peg made of hardwood is one of the oldest fasteners. However, the relatively poor mechanical properties (strength and ductility) compared with steel restrict their applications in modern timber construction. ...
Rapid Identification and Location of Defects behind Tunnel Lining Based on Ground-Penetrating Radar
Publisher: ASCE
Abstract: Ground-penetrating radar (GPR) is a mainstream tool to detect defects behind tunnel linings, but the difficulty in interpreting GPR signals limits its application. This paper proposes an intelligent way to differentiate ...
Shear Modulus Degradation Curves of Gravelly and Clayey Soils Based on KiK-Net In Situ Seismic Observations
Publisher: American Society of Civil Engineers
Numerical Investigation of Transition Mechanism between the Two Kinds of Compressional Waves in Saturated Geotechnical Media
Publisher: American Society of Civil Engineers
Abstract: The hydromechanical coupling effect between soil skeleton and pore fluid phases, that is, dissipation of dynamically induced excess pore water pressure, can be a critical factor in determining the dynamic response of ...
Pullout Resistance of Densified Wood Dowel Welded by Rotation Friction
Publisher: ASCE
Abstract: Rotation welding is a novel technique to produce structurally efficient wood joints without any synthetic adhesives, in which wooden dowels are inserted into timber members by high-speed rotation to form the bonding interface ...
Mechanical Properties of Adhesive-Free Cross-Laminated Timber
Publisher: ASCE
Abstract: In order to reduce the use of adhesives, the development of adhesive-free engineered wood products is one of the research focuses in timber structures. This paper studies the mechanical properties of cross-laminated timber ...
Degradation Mechanism of Nonaqueous Reactive Polymer Grouting Materials under Chemical Corrosion Environment
Publisher: ASCE
Abstract: Nonaqueous reaction foam polyurethane (PU) grouting materials have found wide applications in civil engineering. However, degradation laws and mechanism of the strength performance of PU grouting materials in different ...
Pull-Out Performance of Timber Joints with Glued-In Densified Wood Dowels
Publisher: ASCE
Abstract: Densified wood (DW) dowel is worth considering as an alternative to steel rod for timber joints with glued-in rods, because it is more naturally harmonized with timber members, and has better resistance against corrosion ...
Mechanical Behavior of Timber Joints with Laterally Loaded Multiple Densified Wood Dowels under the Loading Parallel to the Grain
Publisher: American Society of Civil Engineers
Abstract: Aside from aesthetic appearance, recycling, ease of disassembly, decent resistance against corrosion, and no intense moisture condensing and thermal bridge, compared with steel fasteners, wooden fasteners also have the ...
