I don't think the attached doc. worked, so here it is once more.http://files.engineering.com/getfile.aspx?folder=91f2ceef-1291-4697-af78-35b2cb240e72&file=MOU%202005.pdf

See attached for what a B train is. This information has lengths and wt's but I need to know the ground clearance limitations for a B train or for any other big rig trailers. Thanks, Mhttp://files.engineering.com/getfile.aspx?folder=d379707c-f1b9-4987-a926-14275278f63c&file=MOU%202005.pdf

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, M.

Can you please clarify the last sentence regarding the floating clips?

Unfortunately I am very limited to roof height while maintaining the ceiling height inside. I am stuck with the hot rolled sections. I know I’m going to get flack from the guys in the field about that, but like I said, I have no room for the roof to grow up nor down. I guess I could use...

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...

Hi all; The Canadian version CSA A23.3 Annex D commentary states: "These equations are not applicable to J or L bolt anchors for which there are currently no side face blowout expression. L blots located in close proximity to a free edge with the hook orientated parallel to the free edge...

A paper called "Practical Yield Line Design" is quite good. You can find it at: www.concretecentre.com Hope this helps.

Is this a slab-on-grade or an elevated slab say the second floor?

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...

Try ASME BTH-1 and "Proposed Deisgn Criterion for Vessel Lifting Lugs in Liew of ASME B30.20" by Dennis K. Williams.

Are there any thoughts of using what is suggested by the Army TM 5-852-5 report "ARCTIC AND SUBARCTIC CONSTRUCTION: UTILITIES, Chapter 12: Thermal Considerations" http://www.army.mil/usapa/eng/DR_pubs/dr_a/pdf/tm5_852_5.pdf

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...

A Manual Concrete Rebound Test Hammer can be used if you are concerned with non-destructive testing of hardened concrete for it's compressive strength. However, there are some pros and cons to it.

Thanks to those who contributed with meaningful comments. The client asked the question if the shack is required to be anchored down even if the wind loading would not compromise the factor of safety for sliding or overturning. Obviously putting in anchor bolts would be the wisest thing...
