I have a few free standing stairs and platforms that seem to be swaying a little too much for the people using them. These stairs and platforms have been analyzed for loads specified in ASCE-7 and deflections limited to 1/4 inch. I recommended and designed cross bracing to limit the sway. I...
Where can I find plots for the combustion of compounds such as dimethyl disulfide, methly mercaptan, dimethyl sulfide, hydrogen sulfide vs. percent oxygen and temperature. I am trying to determine HAP remove efficiency in flue gases using the excess oxygen and the temperature of the flue gas.
We generate 5,000 gallon batches of spent caustic scrubber from stack emission control. The routine is to ship off site by tanker truck for treatment. We are looking into alernatives. We use to treat on site when we had a pretreatment plant, which we demolished.
My first step is if I can apply...
Aside from the Tables in the AISC Manual
where can I find more variations of beam and angle combinations? Is there a way to calculate S1 & S2 & I?
Are there any programs available?
When analyzing the deflection and maximum post span of curved railings I understand with a large radius I can safely apply the equation for straight railing section. But what is the limit? At what minimum radius does the equation need to be modified? What is the analysis for a curved section of...
I would like to elaborate and continue this discussion on moment connection.
thanks for the info you helped me alot.
OK a moment connection transfers the moment from one section to the connected section. This is common with a beam to a column and a beam to a beam in line. But what if the...
What are the shear forces on a bolt connecting a strut to a concrete floor? The strut is supporting a flight header for a stair platform and another strut supports the platform header.
How does a moment connection differ from a fixed connection for a cantilever beam, and how does the calculations differ when analyzing the bending moment?
