![]() ![]() For example, say to reduce the stiffness of the section on cracking, the moment of inertia about local y direction could be reduced by a factor. As boxed out in the image above, suitable modification factor could be applied for changing the cross sectional area, shear area, torsion moment of inertia or weight for any section at desired location and in desired direction. Select the section whose capacity has to be modified from the ‘Section Manager’ window and input the appropriate reduction factors. From Main Menu select Properties > Section Manager > Stiffness… To model a section as cracked and to arbitrarily reduce its load carrying capacity, its stiffness could be reduced, by applying Stiffness reduction factors. ![]() Section stiffness could be reduced or manipulated using the Section Manager under Properties tab.
