Abstract: The use of carbon fiber–reinforced polymer (CFRP) grid-reinforced engineered cementitious composite (CFGRE) systems to strengthen concrete-filled steel tubes (CFSTs) offers potential to improve the structural response as ...

Abstract: This paper presented an experimental study on the dynamic biaxial mechanical behavior of steel fiber-reinforced recycled-aggregate concrete (SFRRAC) samples. Five control variables, including lateral pressure (σ2), strain ...
