Performance of shear connectors at elevated temperatures ? A review

摘要: Shear connectors are key components to ensure the efficient composite action and satisfactory transfer of shear forces at steel'concrete interface in beams. Under hazardous circumstances, such as fire a building, performance beam significantly relies on connectors. Studies behavior subjected elevated temperatures performed last decade reviewed this paper. The experimental testing push-out specimens, design approaches provided by researchers different codes, major failure modes, finite element modeling highlighted. critical research review showed that strength connector decreases proportionally with increase temperature. Compared volume work published ambient temperatures, few studies under have been conducted. Several areas where additional is needed also identified
