The plastic section modulus is calculated as the sum of the areas of the cross section on either side of the PNA, each multiplied by the distance from their respective local centroids to the PNA. [16] = + where: A C is the area in compression A T is the area in tension y C, y T are the distances from the PNA to their centroids. Plastic section ...
English: The cross-section of an I-beam with dimensions for calculating the section modulus. The arrow indicates that the section modulus is being calculated for the weak axis. The arrow indicates that the section modulus is being calculated for the weak axis.

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. When designing a symmetric I-beam to resist stresses due to bending the usual starting point is the required section modulus. If the allowable stress is σ max and the maximum expected bending ...
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
In the case of steel products such as sections, bolts and fabricated steelwork the CE Marking demonstrates that the product complies with the relevant harmonized standard. [7] For steel structures the main harmonized standards are: Steel sections and plate – EN 10025-1; Hollow sections – EN 10219-1 and EN 10210-1; Pre-loadable bolts – EN ...
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
Section Beams are made of steel and they have a specific lengths and shapes like Ɪ-beam, 'L', C-channel and I flanged beam. These types of section are usually ...
