I have a small 18"dia x 42"deep drilled sonotube pier being installed for a swing gate. Top of pier will be flush with grade. The gate will impart vertical axial load on the pier and a bending moment. No shear loads. IBC 2012 1807.3, equation 18-1, provides a depth calculation using lateral soil...
Hello. I've been using STAAD.Pro for only a few weeks now with the CONNECT edition. I have a simple structure which will be covered with canvas and it made up entirely of single angle sections. When I model the angles, I'm rotating the cross-sections 45deg in order for them to be aligned with...
Hello,
I'm working on a job using BS 7159 code for the first time. I'm not sure how to set up the load cases in Caesar II. I believe the code states that only the operating load case needs to be satisfied, but that it should include wind as well. What about for checking the pressure or weight...
Good morning.
I haven't had much luck recently in finding information on when to use rubber expansion joints and when to use metal. My expansion joint experience is limited. If either can be used, what information is critical to choose which to use? How do they differ?
Thanks,

Hello.
Is there a rule of thumb for choosing a design temperature when only an operating temperature is provided for analysis? On my current project, both design and operating pressure have been chosen, but only the operating temperature.
I remember hearing some years back about simply adding...
Hello all,
My company wants me to get my PE, as do I. I work full time and have a pregnant wife at home (2 months so far!:D). I want to take the exam in April but am afraid I won't have enough time to get prepared if I start studying next week. My wife is due in August so those last few months...
Hello,
My company is currently stress analysing a series of 36" vent/releif lines. The main relief line has a 36" rupture disc and also a 10" connecting branch line with a PRV. The design pressure for the line is 150 psig. Doing a simple thrust force calculation of F=P*A results in a very high...
Hello,
I'm currently doing stress analysis in Caesar II on an existing 8" SS line with a design temperature of 1400F. The client would like to know if the line is overstressed and potentially replace it if so. Since this is an existing line, the analysis uses all of the existing springs and...
Hello all,
First time poster with a stress analysis inquiry.
My company is working on analyzing a 4" line @ 150° in a tank farm. The line runs through berms and spans approx. 200' in between each set. The client does not want any loops in the pipe between the berms and would like to know the...
