what is typical design for expansive clays in light loaded commercial facility...I assume integral gradebeams and slab. Any suggestion for design guide...PT not in the budget or design scope, only rebar. Building is about 100' square with a couple column loads and ligh bearing wall line load...
Is there such a spreadsheet? Don't need a CAD program or survey program. More like a math program. We did area calcs by hand in school....somehow by putting in angles and distances.

Need to find the tensile capacity of a bolt in a tapped hole condition.
Lifting a tank that has 6-3/8" tapped holes about 3/8" deep. Tank flange is Cu-Ni and weighs about 5,000 lbs. Considering FS of 2 on lift and additional 20% for prying action on bolt heads. Therefore I need a...
Is there any special wind load provisions necessary at airport facility structures due to jetwash or rotor wash from helicopters? I haven't seen or found anything. Any military specs maybe??
We've been seeing more precast box structures for small wastewater plant applications. Most are two or three piece stacked similar to manholes. Concern is very thin walls for buried application (2 3/4" is the smallest!) and wire mesh reinforcing. Design is by yield line analysis for two...
Looking at a 10 year old clearwell that has been exposed to an aggressive water with a Langlier Index of -1.3, Alk of 76 (mg/l as CaCO3), Hardness of 160(mg/l as CaCO3), and CO2 of about 50 mg/l. After 10 years the cement paste has been "dissolved" to about 1/4" in depth and only...
