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...

Thanks Gentlemen. Ryan Erick Broomé, S.E., P.E.

I couldn't find it in the help file. Where did you find it? That would be enough to help me out. Ryan Erick Broomé, S.E., P.E.

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 Ryan Erick Broomé, S.E., P.E.

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...

Thanks so much for your help. That is exactly what I needed. Ryan Erick Broomé, S.E., P.E.

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? Ryan Erick Broomé, S.E., P.E.

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...

You could try contacting Bowman Morton MFG & Machine Inc. 6276 Ellis Avenue South Seattle, WA. 98108 Phone: (206)524-8890 and see the ICC-ER report at: http://www.icc-es.org/reports/pdf_files/UBC/5354.pdf Good luck

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...

I would contact them to see if they have an ICC Evaluation Report. It can tell you most of the information you may have concerns about. I have previously designed with Permier Sandwich Panels (ICC PFC-5002) and it worked out rather well. That was for New Mexico and the seismic and wind...

It appears that your situations resembles Fig. A-16-4 and that the hr cannot be greater than the ridge height otherwise there is no longer a structure for which the snow can drift against. This is of course the maximum drift load and it would change linearly down to the eave height using the...

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...
