\\ *Property modifiers* may be used as a scale factor to modify the stiffness of section properties for [frame|kb:Frame], [shell|kb:Shell], and [tendon|kb:Tendon] objects. Property modifiers may be assigned either to object sections or to the objects themselves. h1. Shear release A *shear release* may be applied to a structural member by assigning a sufficiently small property modifier to f12. This modifier could be on the order of 10{^}-4{^} times smaller than the other stiffness properties. It is best to use a small value such that [numerical problems|kb:Numerical problems] do not impede the formulation of a numerical solution. h4. Shear walls A shear release may be useful to release certain *shear walls* from in-plane shearing behavior. To release out-of-plane shear, assign the small property modifier to m22. This should allow walls to function only as bearing walls. {hidden-content} *Related Incident:* * {incident:no=48531|comment=Releasing walls to cater for high shears} {hidden-content} |
