But this becomes more apparent when, say you have someone else doing the connections and your communication with that someone is vague, or among other things, you just lost focus and suddenly you designed all connections as pinned. The connections that we assumed as either pinned or fixed during analysis should also be detailed as pinned and fixed respectively, when designing connections. I cannot emphasize it enough so I’m going to repeat it again (redundancy for emphasis): consistency, consistency, consistency. Just a word to remember when designing connections though: Consistency, Consistency, Consistency So if you already have a stable framing, the members are working and the allowable drift and deflection requirements are met, all that is left is to design and detail the connections. All of which in consideration to a sound and stable framing system.Īnd we also discussed that aside from member design, whether you are using allowable stress design (ASD) or ultimate strength design (USD), we have to ensure that the lateral drift and the deflection are within the allowable limits as prescribed by relevant codes. In my last post, we discussed about the structural framing, on where we should put “pinned” and “fixed” connections.
