Hi
We are designing the pipe support system for gravity and seismic loads, while another party is responsible for the thermal load analysis. Our standard approach is when a pipe is supported from a concrete ceiling or frame using a clevis hanger and threaded rod, and unless it is braced, we...
Hello Everyone,
I have recently been getting jobs to analyze rooftop curbs for seismic/wind certifications. These rooftop curbs support RTUs with large areas, so wind is the governing load. Since this is new for me and lack of any references, I am only checking for compression buckling and...

Hi Everyone,
I have a question. The consultant is asking for the pipe clamp capacity installed in different orientations. See attached drawings. I attempted to apply curved beam theory using Roark's formula, table 9.2 case 4, but the result is not quite convincing. Even though I reached out to...
I have a quick query regarding the vertical excavation of the soil. Nowadays, our city has issued a new advisory stating that any excavation occurring within 10 feet of the property line needs to be reviewed by a P.Eng. In the urban setting, due to the limited space up to the property line, the...
hello,

The neighbor of the client is going to...
