Filter by Author9 report(s) found for Yail "Jimmy" Kim 1 - 9 of 9 This report presents the behavior of reinforced concrete beams retrofitted with carbon fiber reinforced polymer (CFRP) sheets and ultra-high performance concrete (UHPC) jackets in a multi-hazard environment. Following the procedural protocol of a published standard, the beams are cyclically loaded under... This report presents the relevancy of the allowable stress rating (ASR) and the load and resistance factor rating (LRFR) methods for timber bridges. Benchmark bridges constructed in the 1930s have been upgraded with hollow structural steel (HSS) beams and three-dimensional finite element models provide... The first part of the study presents the time-dependent interfacial behavior of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips bonded to a concrete substrate using inorganic resins. Four types of bonding agents (mortar, polyester-silica, ultra-high performance concrete (UHPC)... This report presents a comparative experimental study on the axial behavior of concrete subjected to alkali-silica reaction (ASR) with and without confinement by carbon-fiber reinforced polymer (CFRP) sheets. A total of 120 cylinders are cast using two types of coarse aggregates to represent variable... This report presents the feasibility of a novel anchor system that mitigates the end-peeling of carbon fiber reinforced polymer (CFRP) sheets used for strengthening reinforced concrete beams. Contrary to conventional anchoring methods, CFRP sheets are embedded inside the pre-grooved concrete and covered... This report presents a research program studying the grooved bonding schemes of composite sheets (carbon fiber reinforced polymer, CFRP) for rehabilitating concrete members. The first phase of the research presents the efficacy of functional periodicity on controlling the occurrence of interfacial failure... This report presents a two-phase research program studying i) galvanic current influencing deterioration of carbon fiber reinforced polymer (CFRP) sheets bonded to a steel substrate and ii) electrochemical reaction for steel beams strengthened with CFRP. The first phase of the research presents an experimental... This report presents a two-phase research program studying i) the interfacial response of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips embedded along a concrete substrate at elevated temperatures and ii) the behavior of NSM CFRP strips for strengthening concrete members subjected... This report presents a two-part research program examining the performance of constructed bridges in a cold region, represented by those in the State of North Dakota, and the behavior of concrete members strengthened with carbon fiber reinforced polymer (CFRP) composite sheets in such a service condition.... |
