The study presents the performance of flexural strengthening concrete members exposed to partially unbonded prestressing with a particular emphasis on amount (0, 14.2, and 28.5%) cut strands-symmetrical asymmetrical damage. In addition examining influence strands remaining capacity post-tensioned effectiveness carbon fiber reinforced polymer laminates restoration, investigated results rectangul...

To fully recognize the load-resisting mechanisms of post-tensioned concrete (PC) structures with realistic boundary conditions against disproportionate collapse, four beam-column subassemblies were extracted from a prototype building and side columns joints reproduced to reflect actual condition. The parametric analysis was conducted, including location removed column (middle or penultimate) st...

The development of strong and stiff lateral load-resisting systems (LLRS) is essential for mid-rise high-rise timber buildings. On the other hand, within a seismic design philosophy, strength/stiffness ductility/drift capacity typically appear as opposite target parameters, depending on acceptable level damage. For improved stiffness strength, core-wall tubular structural forms commonly are use...

Pre-stressed members in various structures are gaining popularity among engineers many parts of the world because pre-stressed strands offer better stability, serviceability, economy, aesthetics, and structural efficiency. The profile strand greatly influences tensile strength concrete. force exerted by on concrete counterbalances internal forces. A construction engineer’s principal goal is to ...

Since, it is essential to provide homeless people by the earthquake with safe, habitable accommodation repairing medium and slight levels of damage at the connection parts should be undertaken. In order to prove that a repaired connection was sufficiently strong, a precast beam to column post tensioned connection was tested in three phases. In phase one, the middle level damage was observed at ...

The present paper investigates an innovative seismic-resilient bridge column-footing socket connection (SC) for post-tensioned concrete-filled steel tube (PCFT) columns defined according to the Accelerated Bridge Construction (ABC) requirements. PCFT-SC column uses embedded dissipate seismic energy and unbonded (PT) bars improve self-centering capacity. Experimental tests were performed on a co...

Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...

Studies on the flexural behavior of post-tensioned beams subjected to strand damage and strengthened with near-surface mounted (NSM) technique using carbon fiber-reinforced polymer (CFRP) are limited fail examine effect CFRP laminates strain strengthening efficiency systematically. Furthermore, a design approach for UPC structures in existing guidelines FRP techniques is lacking. Hence, NSM-CFR...
