[Boundary] How to modify the Section Stiffness properties?

Question

How to modify the Section Stiffness properties?

 

Answer

Specific stiffness of specific member types may be reduced such as the case where the flexural stiffness of lintel beams and walls may require reduction to reflect cracked sections of concrete.

From the main menu select Properties > Section > Scale Factor > Section Stiffness Scale Factor.

With this option Section (beam & column), wall and plate stiffness properties could be modified.This function becomes a convenient tool for reducing flexural stiffness by member types.

The scale factors defined here are applied to the calculations for displacements and member forces. For stress calculations, original section properties are used. However, the option for applying the Section Stiffness Scale Factors to Stress Calculations may be selected in Analysis > Main Control Data.
