The behavior of hollow-core columns composed reactive powder concrete (RPC) contained by a circular carbon fiber reinforced polymer (CFRP) tube is investigated numerically in this work. This research used hollow core column samples with an outside diameter 20.6 cm, interior 9cm, and height 80cm. These examples have been created utilizing 116 MPa concrete. Nine groupings specimens were created. ...

The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...
