Damping and flexural properties of prestressed concrete members subjected to reversed cyclic loading
… of structural damping. Part two describes the reversed cyclic testing of prestressed concrete members: end moments were applied to the members to simulate earthquake loading, and measurements were made of stiffness and damping energy. An analytical method of obtaining moment - rotation curves …

Concrete columns and beams reinforced with FRP bars and grids under monotonic and reversed cyclic loading
… phases; (i) columns under eccentric monotonic loading; (ii) reinforced cylinders under concentric compression; (iii) columns under constant axial compression and lateral load reversals, and (iv) cantilever beams subjected lateral monotonic or cyclic loading. The results of tests conducted at …

ANCHORAGE OF HEADED REINFORCING BARS IN CONCRETE
… and seven knee beam-column joints subjected to reversed cyclic loading. The headed bars in the column-foundation joint specimens had net bearing areas ranging from 4 to 15 times the area of the bar Ab; some of the headed bars contained large obstructions adjacent to the bearing face of the head …

Modelling of debonding mechanisms in externally bonded FRP sheets in RC shear walls for earthquake resistance
… with externally boned FRP sheets under the reversed cyclic loading of earthquakes. The proposed computer model can accurately simulate the IC debonding mechanism under the two-dimensional stress state of the wall panel and the subsequent ductile flexural or brittle shear failure modes of …

Fatigue behavior of ceramic matrix composites at elevated temperatures under cyclic loading
… matrix. composites at 1800 of under fully reversed cyclic loading. Notch effect on quasi-static tensile response is also considered. Quasi-static and fatigue damage mechanisms and failure modes are examined using various specimen geometries, load levels, fatigue ratios, and laminates …

Performance Assessment of Shear-critical Reinforced Concrete Plane Frames
… frame analyses under temperature and monotonic loading conditions. Although providing generally satisfactory simulations, there are a number of deficiencies present in its computational algorithms. This study consists of three major parts: improvement of the original analysis procedure for …

Performance Capabilities of Light-Frame Shear Walls Sheathed With Long OSB Panels
… feet (2.4, 2.7 and 3.0 m) were subjected to the reversed, cyclic loading schedule of the standard CUREE protocol in order to determine the performance capabilities of shear walls greater than 8 feet (2.4 m) in height sheathed with long panels. Of the thirty-six walls, a total of twelve walls …

Seismic Behavior of Simcon-Jacketed High Strength Lightweight Aggregate Fiber Reinforced Concrete Filled Steel Tube Column Members
… energy dissipation under extreme earthquake loading and because of the fiber mat feature of SIMCON, used and deteriorated SIMCON jacket can be relatively easily replaced after the end of earthquake loading. Main objective of this research was to manufacture, test and analyze the seismic …

Experimental and Analytical Evaluation of FRP-Retrofitted Reinforced Concrete Diaphragms for In-Plane Shear Strengthening
… specimens subject to a displacement controlled reversed cyclic loading protocol at the free end. The diaphragm specimens were designed to represent the diaphragm shear zone adjacent to a shear wall, a typical location of high in-plane shear demand. Seven specimens were strengthened with FRP, …

Self-healing strain-hardening cementitious composites (SH2CC) for cyclic loading environments
Cyclic loading is ubiquitous and frequently encountered in various infrastructure. However, the widely used construction material, concrete, is inherently brittle and could be poor at sustaining cyclic stress (especially those involving tensile stress). Although reinforcement can help avoid …
