Hi to All,
What is a reasonable number of DCP tests to verify compaction of fill soil compacted for a residential slab foundation (approx. 1800 sq ft of slab)? Thanks for your input.
Is there a limiting unbraced length for circular steel pipe in pure bending? (if not, then is the allowable tension and allowable compression the same?)
A Pool Contractor in business for 30 years has used #3 bars at 12" o.c. in 6" thick pool slabs and walls (5' high) in all of his pools. No significant problems with cracking have occurred.
Question 1: does shotcrete and normal concrete have the same requirements regarding temp and shrinkage...
A36 structural steel beam w/ 4 bolt holes (13/16" dia.) at end were misaligned by the fabricator. The holes were drilled approx. 1" offset from the req'd position. Field repair consisted of filling holes w/ e70 weld and redrilling holes in the correct position. Is this repair adequate...
Outside Xmas lights for a theme park do not have a UL listing. Are there other specifications (ANSI, ASTM, etc) that govern the manufacturing of outside lights?
P.S. Power is supplied thru GFCI receptacles.
I am trying to develop a preliminary plan for a church facility (i.e. activity center). Specifically, I need to know the number of commodes required by code so that I can minimize the restrooms as much as possible (IBC2000 - I have the structural code - but not the plumbing code).
The total...
I recently read an on-line report (research from HUD) that current research indicates that residential structures may perform better when the attic spaces are UNvented in climates where ambient humidity is high (say somewhere similar to Charlotte, NC or Atlanta, GA)

For a 2 column 1 beam moment frame designed as pinned at the slab-on-grade (w/ monolithic edge beam) foundation, I assume there will be some moment transferred to the slab.
Is there a prescibed method to determine the amount of moment to resist, or just design for the cracking moment?
Thanks...
A local bldg inspector quoting a bldg code requires 2" clearance between logs of exterior wall (log cabin construction) and a brick fireplace. There is no mention of a liner (w/ or w/o) in the text of the specific code.
I know that the ignition temperature of timber can be significantly...
falsework for cantilever portions of a bridge deck are typically supported by the exterior girder (steel or concrete). North Carolina DOT allows bolt holes in a steel girder web, if done during initial fabrication. This allows connecting a strut to the web that results in a force perpendicular...
For 3-138' continuous spans (P/S bulb tees), how can I show expediantly than intermediate diaphragms are not required. (If I can eliminate the intermediate diaphragms, I can save the contractor approx. $200,000.)
I appreciate any guidance.
