There are websites that can give you the coordinates you need. Geodesic domes are actually more complicated than you might think. There are many types and configurations.
Kodak79,
I do part time consulting for the US Scia office, so i'm a little biased. I won't brag about the benefits and features here but if you send me a PM I could provide you some information.
If there is no collector as shown by the dotted line, how will the small subdiaphram and the upper portion of the large subdiaphram transfer shear into the center wall?
Thanks for the input. I have used enercalc a little. It seemed like it was mostly for individual components within a structure. The shearwall module in Woodworks looks like a huge time saver. The wind and seismic on a complex custom home looks like it could involve alot of book keeping on a...
I'm curious what others are using for light frame wood structures design. I have software for RC & steel design but am starting to take wood jobs also. I know RISA does wood shearwall design. I have been testing Woodworks. An associate of mine uses elaborate spreadsheets. What are you finding to...
I have used Robot. It has some strong features but the interface is very cumbersome. Autodesk bought it a few years ago and so far has done almost nothing to the software as far as improvements. Like I said above, if you like robot I would take a look at Scia Engineer.
I would reccomend Scia Engineer. It's very popular in europe and is getting more popular here in the US. It offers most of the higher end features of SAP and Robot with a much better interface and report generation capabilites.
Josh,
That's the Idea. You have to assume a neutral axis depth. Then the sum of forces is your axial load and sum of forces about the centroid is your moment. It's just that each assumption is only one point on the interaction envelope and you might need a few to check the adequacy of the section.
The second method you mentioned is the one I would use. It's best done with a spreadsheet because you need to do a strain compatibility analysis that includes the effect of axial loads as well. It can be done by hand but pretty cumbersome because you have to use trial and error to arrive at a...
Here is a graph that I have used occasional for a quick and dirty subgrade modulus. Obviously not a replacement for a more accurate value, but better than nothing.http://files.engineering.com/getfile.aspx?folder=dd044c6a-fca4-46eb-bb16-bf289e299f5e&file=Subgrade_Modulus.jpg
