I am connecting a diagonal brace to a beam using a timber screw. The brace may be at any angle to the beam. In the attached I have used C=α. 2015 NDS, 12.4.1, Figure 12F has α=any angle with the screw perpendicular to the main member. But if I rotate the screw, for example 30°, then the C=B-A...
I can find in ASCE Table 3.2-1 Design Lateral Soil Loads to be used for active lateral pressures determined by Unified Soil Classification that I can use as values when I don't have a soils report. However, I cannot find anything for determining a passive pressure to use. Is there a way to...
I want to solve for the diameter (d) of circle for example. A=(π*d^2)/4 for d. I know this is a very simple question, but I can't figure out how to do it symbolically.
Thanks

I previously had written calcualtion sheets in both MathCAD 13 and 2000. Some sheets I created in 2000 won't calculate under V13 and now I find the same thing with V13 files in V15. Any suggestions of how to fix this without having to completely rewrite the calculation sheets?
The attached was...
I have attached a simple file to help illustrate my question. I have the array Wui that gives input values. I need these values to help create another array with the results from Weight_of_Unit. Is this even able to be done and if so, how?

I have a project that has been under construction. The contractor installed regular DF#2 posts embedded in the concrete instead of Pressure-treated. However, he did coat all the bases of the posts with a moisture protection. The beams, trusses and roof sheathing are now on and the problem was...
Since AISC 358-05 does not recognize HSS columns as part of the design requirements for a Prequalified Connection in a SMRF (2.3.2b), I need to use built-up box columns. Can anyone direct me to where I can find a design procedure for such columns? I have limited space which limits the use of...
In reading this paragraph I understand that the forces shall be increased only for the design of the connection of a flexible diaphragm to a vertical elements such as a shearwall or a collector. For example the connection of a diaphragm to the top of a shearwall or drag strut. But what about...
