section modulus meaning

• [Architecture]
  

  The moment of inertia of the area of the cross section of a structural member divided by the distance from the center of gravity to the farthest point of the section; a measure of the flexural strength of the beam.

• 
  [Mechanics]
  The ratio of the moment of inertia of the cross section of a beam undergoing flexure to the greatest distance of an element of the beam from the neutral axis.

• section modulus of transformed section
• The plastic section modulus depends on the location of the plastic neutral axis ( PNA ).
• The section modulus of different profiles can also be found as numerical values for common profiles in tables listing properties of such.
• Often the equation is simplified to the moment divided by the section modulus ( S ), which is I / y.
• There are two types of section moduli, the elastic section modulus ( S ) and the plastic section modulus ( Z ).
• There are two types of section moduli, the elastic section modulus ( S ) and the plastic section modulus ( Z ).
• The plastic section modulus is used to calculate the plastic moment, M p, or full capacity of a cross-section.
• "' Section modulus "'is a geometric property for a given cross-section used in the design of beams or flexural members.
• The ideal beam is the one with the least cross-sectional area ( and hence requiring the least material ) needed to achieve a given section modulus.
• The farther a given amount of material is from the neutral axis, the larger is the section modulus and hence a larger bending moment can be resisted.
