Joint behavior in analysis
Joint behavior in analysis
(OP)
Have a question for those who utilize truss design software for wood trusses. How does the software handle joints in the trusses? Typical truss theory suggests pin-type connections, but actual behavior of the metal plates used in manaufacture seems harder to predict. All them protrusions on those gangplates sinking into the wood makes me wonder about moment releases and such that are critical when modeling structures.





RE: Joint behavior in analysis
Today, softwares utilize stiffness/virtual work methods to analyze more complex truss designs which are often indeterminate, together with partially rigid joints and empirical formula conditions usually at short cantilever/bearing conditions.
