Abstract: Reinforced concrete (RC) frame structures are widely used in earthquake regions, and damage to these structures has been reported after many earthquakes. Small parts of seriously damaged RC frames should be demolished and ...

Abstract: During the last two decades, the use of fiber-reinforced polymer (FRP) in the retrofitting of concrete structures has been widely studied. However, there is limited research on the effect of initial concrete damage on the ...

Abstract: A one-bay two-story reinforced concrete (RC) frame structure with weak beam-column joints was damaged during structural vibration control testing using a shake table. A damage assessment of the structure was conducted, and ...

Abstract: To investigate the size and slenderness effect on the axial-compressive behavior of basalt fiber–reinforced polymer (BFRP)-confined predamaged concrete, five groups of concrete cylinders with different sizes and slenderness ...

Abstract: A fiber-reinforced polymer grid-reinforced engineered cementitious composite (FRPECC) is a promising strengthening composite that addresses the drawbacks of FRP and textile-reinforced mortar (TRM). The present study focused ...

Abstract: This study investigated the monotonic and cyclic axial compressive properties of predamaged concrete retrofitted using externally bonded basalt fiber-reinforced polymer (BFRP) sheets. Plain concrete cylindrical specimens ...

Abstract: Natural fibers have become a research hotspot in composite materials recently. This study investigated the axial compressive behavior of predamaged concrete repaired by jute fiber–reinforced polymer (JFRP) composites. ...

Abstract: Based on the stochastic process multiple threshold crossings analysis formula, the impact of structural response random process crossing-threshold duration on structural fatigue reliability is studied, which was not involved ...
