Hi everyone:
-we are building a tunnel in west coast that is underlined by liquefiable soil deposit. We need to estimate settlement-induced liquefaction under the tunnel. The current formulas are only able to estimate volumetric strains . Based on my understanding, these are applicable for...
Hello everone.
I have a pipe buried at 3 ft below river bed at stream crossing. The water level is 10 m above river bed. When checking if the pipe is going to be uplifted under hydrostatic water pressure, I noticed that in literature when calculating upward hydrostatic force under pipe, only...
Hello,
For gas pipe (buried at around 5 to 6 ft), I am trying to determine the Minimum Design Temprature for toughness purpose. I am assuming that minimum designTemperature of the pipe can be the same as the minimum ground temperature at that depth (5 to 6 ft).
The question is how to obtain...
Hello,
I am trying to get the transitionTemperature under Static conditions (for analyzing fracture initiation or pressurized vessels) from the transition temperature obtained from traditional Charpy_CV or DWTT tests.
Can you please refer me to the correlations or related references, if...
Hello everybody,
I have a steel buried pressurized pipeline with two induction bends (L-shape)and (Z-shape). I need to run a quick calculation to check the stresses induced by temperature differences. I am following Peng's old approach ( paper is attached). According to Peng, we have to...
Hi everyone,
I do remember that ASME has a table proposing values of oil and gas pipeline parameters inducing toughness (conservative values), in case one does not have these parameters in the analyses. Unfortunately I can't find the document . Anyone can help..?
Thanks
Hello,
can anyone tell me please where I find analytical formulas for cantilever beam on the elastic foundation (e.g compacted soil) under uniformally distributed load and under end moment or deflection.
Thanks for your support.
