WebThe CBUSH element does not represent the bolt; it represents the joint. A bolted joint with preload has a very large bending stiffness, because the flanges press against each other and are not allowed to interpenetrate. Here are more reasonable values for metallic bolted joints in the 1/4" to 1/2" size range.
