![]() ![]() When the structure goes beyond that, I'll get my local structural engineer to provide me with some sealed detail sketches and either scan them into my layout sheet or have him seal my structural sheets. I also found a conservative deck design guide that's based on the 2006 IRC called "Prescriptive Residential Wood Deck Construction Guide" from the American Forest & Paper Association,inc. In regards to beam calcs and span charts, I typically use the one's in my IRC 2009 code books for lumber and use the tables provided by Trus Joist for lvls, psls etc. I vaguely remember having to do do more steps to perform certain functions in Softplan and feeling that Chief gave the feeling of a more direct "hand to brain" connection.įinally, have they improved the roof creation tool or is it still a bit counter intuitive to use? I didn't use the program long enough to master their roof tool. Why would you be using both Chief and Softplan instead of just mastering one (or have you mastered both?). I briefly learned and used Softplan v8 & v9 when it was still DOS and not Windows based. Where ceiling joists are used to provide resistance to rafter thrust, lapped joists shall be nailed together in accordance with Table. SCOPE hese span tables for joists and rafters are calculated T on the basis of a series of modulus of elasticity (E) and bending design values (F b). Regarding structural framing plans, detailed sections, control and accuracy how does Chief compare to Softplan? Can you now manipulate framing members etc in 3d views with Softplan? When I was using it, I don't think you could move windows from an elevation view but If you moved them in plan view they would move in 3d. SPAN TABLES FOR JOISTS AND RAFTERS 1 AMERICAN WOOD COUNCIL EXPLANATION OF TABLES 1. It is nice because the program will insert what is need automatically based on the input data from the span tables. ![]() I also use SoftPlan which does allow the import or manual entry of local span tables, which are almost always available from the local code office. Unfortunately Chief does not include the ability to enter a specific span table for the program to revert to whenever a certain distance is spanned, similar to the way the headers are sized. Once the design is pretty much complete as far as the overall structure it will then be necessary to calculate loads as well but most use an engineer for such anyway. Obviously loads are not allowed for but it's a good start. Thanks!I use several software packages due to the fact that where one fails the other excels. For all other applications click here to go the reference in the code book.Does CA do any calculations or determinations of joist, beam or rafter sizes and spans? Is there any sort of a module available or other program that can be tied in for this? We usually do our own, of course, but I was wondering how CA's recommendations might compare to other methods of calculation. Living areas are sized for 40 lb live load plus 10 lb of dead load(20 lb for ceiling). Bedroom areas are sized for 30 lb live load plus 10 lb of dead load(20 lb for ceiling). These six tables cover the most common situations for 16″ o.c. 2 pine or other material can span as a floor joist according to 2018 International Residential Code for living, bedroom, and storage areas.
