Hello all;
I'm looking for information regarding the curb height such as the clear distance between road and the lowest point on the trailer of a B-train.
Thanks,

Hello all;
I am currently designing a single story steel framed building for an industrial application (W sections for columns and roof beams, cold formed channels for girts, and channels for purlins (roof heights have limited me to small C4's for purlins instead of using the traditional cold...
Per NCB there are two methods for determining wind pressure for low rise buildings using external pressure coefficients. One for the primary structure (such as columns and beams)(fig. 1-7) and one for roofs and walls (fig 1-8 for wall and 1-9 to 1-14 for roofs).
I have no problem in determining...
Hello All;
How would one go about protecting an underground pipe from the effects of frost if the pipe happens to be within the frost penetration zone of the soil. I have the Army TM 5-852-5 report “ARCTIC AND SUBARCTIC CONSTRUCTION: UTILITIES, Chapter 12: Thermal Considerations”, where it...
Hey;
Is it stated any where in a code that a structure must be anchored down, specifically, anchored with anchor bolts to a foundation? I have a small shack (40ft long x 12ft wide x 12ft high, approximatly 41,000 lbs heavy.). Do I need to anchor it to the foundation per any codes in Canada...
Hey all.
How would you approximate the ton of reinforcing in say a footing? I am doing a quick estimate of material quantities (cubic yard of concrete, ton of re-bars, etc.) for a foundation. I have not done a design of the footing and I don't know the loads applied to it, but I did guess the...
Hello All;
I’m currently reviewing a concrete floor slab (elevated) from the 1940’s. Does anyone have any information regarding reinforcing rebar back in the 40’s? The rebar schedule is calling off 1” square and round bars. Were there standards for rebar back then because I have never heard...
Will anyone have any information for design of a guy wire supported stack. I have this publication name, but I can not find it any where. Any and/or all help will be great.
Thanks,

Hello All;
To calculate equivalent static vortex loading, ASME STS-1-2006 uses a "normalized mode shape". How does one calculate this "normalized mode shape". I use Risa to calculate the natural frequency and mode shapes of the stack, but how do you make the mode shape into a normalized mode...
