Curvature stress relationship
WebThis relationship gives the bending strain at any location as a function of the beam curvature and the distance from the neutral axis. However, this equation is of little use, and needs to be converted to stress. Also, … WebFeb 15, 2024 · In this paper, a parametric analysis of the moment-curvature behavior is conducted based on the simulation of the load-displacement curve of an SFCB-reinforced concrete beam; the corresponding curvature ductility index is also discussed. The research results of this paper can provide a reference for the design of hybrid reinforced concrete …
