Stronger Post-to-Beam Connections | Professional Deck Builder ...23 Sep 2013 ... The most under-appreciated connection on a deck frame is probably the one between a post and the beam it supports. Although this joint may not get the respect it deserves, it is a critical load-path connection that needs to keep the post and beam aligned while properly transferring deck loads to the footing. A less obvious but equally important function is resisting uplift loads. And when a lateral force is applied to the post, the connection also has to resist beam rotation ...

Joist Layout for Stronger Decks | Professional Deck Builder ...20 Mar 2013 ... How many decks have you been on that bounce or vibrate under foot? Though it's an uncomfortable sensation, in most cases it doesn't suggest an imminent structural failure, just joist spans stretched to the max.

Sizing Posts | Professional Deck Builder | Foundation, Framing ...1 Sep 2011 ... As a post gets taller, the load it can support gets smaller. To better understand the dynamics of post cross-section and height, consider this analogy. With higher decks, I build the frame on temporary 2x4 posts so I can plumb down to find the exact pier locations. If I don't beef up those 2x4 braces before loading the decking on the frame, the posts will bow under the load. On a deck that's lower to the ground, the 2x4 braces will be shorter and won't bow as much, ...

design - Can I get away with 5/4" cedar decking across a 24" span ...I'm a code official and you should ask your authority having jurisdiction. The answer depends on if you need a permit. The 2x4 or 2x6 decking is likely based on the requirements of the International Residential Code which prescribes a 40 psf floor load on any permitted structure, section R105.2. A Play Structure, however, is exempt from a permit under the IRC, therefore, you can use any material as long as it is safe and need not follow the prescriptions of this code.

Calculate Deck Load Capacity - Tributary Area - DecksGoWhat a great question. The issues around deck load capacity is one I receive often from visitors asking how much weight they should design their deck for. The discussion quickly leads to the overall strength of the framed structure. But that is only one part of it. That's because any analysis of what load a structure may bear upon itself and its foundation must involve the support post network and soil bearing capacity.
