I wanted to call the attention of folks on this forum to a post I just made in the Foundation Design Forum called: "ASCE 7-16/22 12.13.5 Strength Design for Foundation Geotech Capacity, Resistance Factors" ... which poses questions on the origin and correctness of resistance factors for...

It seems to me that there is a flaw in the establishment of resistance factors for "strength design" of foundations for geotechnical resistance in CH 12 of ASCE, starting w/ 7-16 and unchanged for 7-22. 12.13.5 permits "strength design methods" for geotechnical design of foundations, i.e...

A little follow up-- I believe the "c" stands for "corrugado" (corrugated) to indicate deformed bars. Some other small diameter bars are designated with the letter "l" which probably stands for "liso" (smooth). Any Spanish speakers out there than can verify this? Still wondering about the sizes...

Looking at some plans for a bridge in Mexico and the longitudinal bars for for the columns are designated as diameter "8c". If they are standard US #8 bars, the reinforcement ratio for the column would be about 1%, which seems reasonable, but curious to see if anybody can verify how their system...

I am modeling the performance of the foundations of a bridge that suffered damage due to foundation movement during an earthquake and need some assistance in properly describing the bridge structural systems. My background is geotechnical and I am primarily concerned with modeling the foundation...

When the cell pressure (i.e., confining pressure) is applied to the sample via increasing the pressure of the water inside the chamber, does it induce equal stress on the top and sides of the sample? I'll spare you the task of explaining to me that fluid pressure acts equally in all direction--...

I'm leaving my job soon to begin a PhD and will have the opportunity to do some small geotech design jobs on the side for a contractor I used to work for-- mostly ground anchor design and observing load tests on anchors. The total revenue from the work will almost certainly be less than $15k per...

Follow up question-- what do I need to do in terms of making myself a legal business? Incorporate? Start an LLC? What's the cheapest option?

I recently had a senior engineer get rather miffed that I had used the word "conservative" on some foundation calcs that I did. He essentially said, "Think about what that word means. You're not being conservative; just say what you really mean." I think what he's suggesting is that we...
