EXPERIMENT STUDY ON REACTIVE POWDER CONCRETE BEAMS USING SPIRAL REINFORCEMENT UNDER TORSION

Civil Engineering

The construction of buildings and bridges have grown more intricate and asymmetrical, with some beams for example, border beams and curving bridges being vulnerable to significant torques. This presents additional problems to the tensional performance of the beam since it is necessary for the beams must be tall torsion capacity and ductility, particularly in typhoon or earthquake prone locations. In order to increase the members' ductility and capacity, continuous spiral reinforcing (SP) has been shown to be superior to standard stirrups in recent years. The shear performance of beams, the seismic performance and bearing capacity of shear walls, and the energy dissipation and beam-column deformation capacity connections are all greatly enhanced by the necessary spiral reinforcing and the application of reactive powder concrete (RPC). Thus, a study examining the relationship between spiral reinforcement in torsion beams and reactive concrete powder (RPC) has been progressively conducted by developing beams with two different types of spiral reinforcement and investigating the effect of spiral development on the torsion capacity of the beam.
