This is my spreadsheet for flat slab design:
The demand and capacity moments moments seemingly have same units( all in ft.kip or ft.lb), however they are not comparable according to the program's error message.
the moment demand is Mu.str_pos is in <ft.kip> uints, while ϕMn.pos seems to be in...
As shown in the attached sketch. The steel pipe pile stops 2" below the cap while the reinforced concrete core continue into the cap.
The intention of such detailing is to force the plastic hinge to be formed underneath the cap and prevent damage to the concrete of the cap.
My question is how...
Not having a chance to take a class in VBA when in school. I want to teach myself VBA. Besides websites, any good books to recommend. I know the basics of EXCEL, I can make very long formulas include BOOLEANs. But I know VBA will make your spreadsheet shorter and more powerful.

Concrete slab 10FT X 5FT , with Hole at center, 3 ftx2ft. supported around the four outer edges, it is a temp cover for drain grate during conctruction.
Modelded with live load( wheel, lane) and dead load, when it comes to shear check, should I use ACI two way slab code, AASHTO Bridge deck( no...
I have a shear key on top of half column, on top of cap-strut, I need to do strut and tie analysis.
can anybody help to draw a strut and tie model (per AASHTO LRFD)
see attached screen shots.
I'm trying to verify SAP2000 does use the Elastic section properties shown in "section properties" in its caculation for dispalcement.
I created a concrete filled pipe section, and build a cantilevered stick model using the filled pipe section, and loaded it with a...
Hi, all,
I need to come up with development lengths for #14, #18 headed bars, as you all know, there is no guidance on how to calculate anchorage strength for #14, #18 bars in ACI 318-08. The equation is limited for small headed bars and with a lot of restriction.
However, CALTRANS has used...

I know the plate dimension( thicknesss and width or depth) needs to be sized according to the moment diagram distribution. could anybody here give me some tips how you...
I'm newbie using SAP2000. I'm using SAP2000 to do my first push-over analysis for a bridge.
I want to know how should I interprete the push-over results, to be exactly.
how do I figure out the yield displacement, ultimate displacement, yield moment, plastic moment for my columns? shoudl I...
