Abstract: The combined action of steel and concrete in composite beams is accomplished via shear connectors that prevent slip between the two materials. In a fire event, the performance of these shear connectors may be impacted, ...

Abstract: The ability of steel-concrete composite floor systems to withstand loads relies on shear connectors, which prevent or limit slip between the two materials. This paper presents an experimentally validated numerical investigation ...

Abstract: Many RC structures experience fire during their service life, after which the evaluation of their postfire performance becomes necessary. Exposure to elevated temperatures due to fire influences the mechanical properties ...

Abstract: This paper aims to develop an optimal design mixture for concrete containing lightweight expanded clay aggregates (LECA) and silica fume with a holistic view in which the mechanical properties, strength retention at elevated ...

Abstract: Pretensioned concrete elements are commonly fabricated with strands 12.7 or 15.2 mm (0.5 or 0.6 in.) in diameter; however, the industry has seen interest in using larger-diameter strands in recent years. The use of ...
