Tag: plastic section and elastic section modulus

Plastic Section Modulus Zp is the Plastic Section Modulus Resisting moment Mp = fy x Zp The plastic section modulus assumes the entire section yields. If the failure is considered till the plastic zone (breaking point) then we consider plastic modulus The plastic modulus is after yielding. Zp is used to determine the maximum bending moment at the point where all fibers have yielded elastically and the entire section is behaving plastically. This is the point when the so-called plastic hinge has developed. Elastic Section Modulus Ze is the Elastic…
