I have a project where the existing clarifier topping slab is being pushed up by a mix of gases that get trapped. The underside of the pile supported clarifier is somewhat dome shaped and gases are coming out of solution in that dome below and are under pressure due to the high ground water...
Does anyone know if the FEMA Seismic Rehabilitation Cost Estimator (SRCE)is up and running any more? The current FEMA site has some files you can download but I can't find the online calculator. It seems to have vanished in Jan 2013.
I'm trying to learn how to use MathCad's ODESolve function but I find my self stuck in very short order and MathCad's help doesn't seem to clarify things much.
In the sample problem I have attached I get a message that the Variable is Undefined in the ODESolve statement. I think I followed the...
RISA's Pdelta analyis kicks out after the deflection reaches 1000 times the initial deflection (RISA Error 2011).
If this trigger (Error 2011) was eliminated in RISA, would the Pdelta analysis of a column converage on the Euler Load (at least roughly converge)?
The attached model should...
Does anyone know of a small (3 or 4 story) steel braced frame analysis model that was analyzed and designed using the 2006 IBC which has a published solution (something similar to the examples in the 2006 IBC Structural/Seismic Design Manual published by SEAOC?)
We're trying to compare several...
Has anyone addressed the issue of a drilled concrete shaft, highly loaded in tension (tower crane leg uplift) and the type of reinforcing laps required under ACI 318?
Specifically, should a 30 inch diameter drilled shaft, loaded to 1200 kips tension be considered a tension tie, thus requiring...
OK, I'm taking a poll here.
As more of the hairs turn gray and the list of projects where the owner wants to add new loads or cut new openings gets longer or where I have to figure out a fix for the positive steel the plumber just cored thru, I find much more comfort in providing sufficient...
