RISFailure Modes and Mechanisms of Shallow Debris Landslides Using an Artificial Rainfall Model Experiment on Qin-ba Mountain
Publisher: American Society of Civil Engineers
Abstract: Landslides triggered by rainfall are a major multiple geological hazard on Qin-ba Mountain. Debris landslides in the shallow layer make up a large proportion of all landslides. A flume experiment was conducted to successfully ...
Determining Extent of Singular-Dominant Region for Interface Cracks Using Deoscillatory Displacement Jumps
Publisher: American Society of Civil Engineers
Abstract: Because of oscillatory asymptotic mechanical behavior, it is difficult to properly examine the extent of the near-front singular-dominant region for interface cracks. An approach is proposed for generating a near-front ...
Thermal-Mechanical Model for Predicting the Wind and Seismic Response of Viscoelastic Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper presents a simplified coupled thermal-mechanical model for the modelling of viscoelastic dampers with temperature- and frequency-dependent properties subjected to long-term and short-term dynamic loading due to ...
Bonding Behavior of Wet-Bonded GFRP-Concrete Interface
Publisher: American Society of Civil Engineers
Abstract: An experimental study was conducted to investigate the interfacial behavior between glass-fiber-reinforced polymer (GFRP) plate and cast-in-place (CIP) concrete placed against this plate—a method known as wet-bonding. The ...
Performance Evaluation of RC Beams Strengthened with an Externally Bonded FRP System under Simulated Vehicle Loads
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber-reinforced polymer (CFRP) sheets can be used to strengthen existing RC bridge girders/decks. The objective of this study is to investigate whether transient vehicle loads present during the installation of ...
Long-Term Behavior of Prestressed Old-New Concrete Composite Beams
Publisher: American Society of Civil Engineers
Abstract: This paper presents both theoretical and experimental studies of the long-term behavior of prestressed old-new concrete composite beams under sustained loads. General differential equations governing the relationship between ...
Prestress Losses and Flexural Behavior of Reinforced Concrete Beams Strengthened with Posttensioned CFRP Sheets
Publisher: American Society of Civil Engineers
Abstract: An experimental study was conducted to investigate the flexural behavior and long-term prestress losses of reinforced concrete (RC) beams strengthened with posttensioned carbon fiber-reinforced polymer (CFRP) sheets. The ...
Uniaxial Tensile Stress–Strain Behavior of Carbon-Fiber Grid–Reinforced Engineered Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber–reinforced polymer (CFRP) grid–reinforced engineered cementitious composites (ECC) have been developed as an alternative to epoxy resin–based FRP plates for the strengthening of concrete structures. To broaden ...
