RISSeismic Performance of Large-Scale RC Eccentric Corner Beam-Column-Slab Joints Strengthened with CFRP Systems
Publisher: ASCE
Abstract: Eccentric corner beam-column joints of existing reinforced concrete (RC) frames, in which the beam axes are eccentric to the column axis, can be highly vulnerable to brittle joint shear failure under earthquake loading. ...
Influence of Axial Compression Ratio on the Seismic Performance of Precast Columns with Grouted Sleeve Connections
Publisher: ASCE
Abstract: Substantial attention has been paid to precast structures due to their obvious advantages. While precast members connected by grouted sleeves are used in seismic regions, studies on the seismic performance of precast column ...
A Detection Method for Bridge Cables Based on Intelligent Image Recognition and Magnetic-Memory Technology
Publisher: ASCE
Abstract: In recent years, more and more disasters caused by the fracture of bridge cables have been reported. Brittle fracture of cables is mainly caused by corrosion fatigue, and thus it is crucial to find cable defects early. The ...
Seismic Performance of CFRP-Retrofitted Large-Scale Square RC Columns with High Axial Compression Ratios
Publisher: American Society of Civil Engineers
Abstract: Numerous reinforced concrete frames have collapsed in major earthquakes because of severe local damage at the ends of columns. Many of these frames were designed and built according to out-of-date codes in which earthquake ...
Static and Cyclic Compressive Properties of Self-Compacting Concrete-Filled Flax Fiber–Reinforced Polymer Tubes
Publisher: American Society of Civil Engineers
CFRP-Confined Square RC Columns. II: Cyclic Axial Compression Stress-Strain Model
Publisher: American Society of Civil Engineers
Abstract: For the seismic design of fiber reinforcement polymer (FRP) confined reinforced concrete (RC) columns, the development of an accurate axial stress-strain model that considers cyclic compression is necessary. In light of ...
CFRP-Confined Square RC Columns. I: Experimental Investigation
Publisher: American Society of Civil Engineers
Abstract: The majority of experimental studies investigating the stress-strain behavior of square concrete columns confined with carbon fiber-reinforced polymer (CFRP) composites have focused largely on unreinforced columns of small ...
Monotonic and Cyclic Axial Compressive Behavior of CFRP-Confined Rectangular RC Columns
Publisher: American Society of Civil Engineers
Abstract: The majority of experimental and analytical investigations on the stress-strain behavior of rectangular concrete columns externally confined with carbon fiber–reinforced polymer (CFRP) composites have concentrated largely ...
Cyclic Load Tests on Precast Segmental Bridge Columns with Both Steel and Basalt FRP Reinforcement
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental investigation of a novel precast segmental bridge column (PSBC) that is longitudinally reinforced with both fiber-reinforced polymer (FRP) bars and conventional steel bars. The major ...
