I have been tasked with developing a synthettic site specific seismic program for our office which will help us determine Site Classes (per IBC) and spectral responses based on past, nearby earthquakes. I have run across mentions that the Monte Carlo statistical method is often used...
Does anyone have any literature, of knowledge of, the shrink/swell potential of shales?
We are looking to use New Albany shale as a structural fill on a particular site. Is there a criteria for determining if this material has excessive sulfide content?
We have performed some work out of country where conventional SPT was not employed. Rather, dynamic penetrometer soundings were performed. Specifically, the method employed is referred to as "DPH". Could someone provide me with information that will convert the DPH data to standard blow counts?
Does anyone have any literature regarding shear wave velocities in a shot rock fill. The structural engineer is inquiring about obtaining a site class B (as per IBC 2003) for a multi-story building. the site conditions are such that 30 feet of fill is required to achieved proposed subgrade...
Can anyone provide me with information regarding the reliability of using 7-day breaks to gauge the 28-day compressive strength. With standard 6"x12" cylinders, about 65% of 28-day strength after 7 days of curing is reasonable. Is there a similar "rule-of-thumb" for cubes...
I first want to point out that this thread is an attempt to obtain information provided in another thread. It seems that so many people have responded to the ringwall foundation thread ("Concrete Pad for Tank"), that I fear many requests for the subject article are going unfulfilled...
Could someone provide me with a good textbook definition of "right of way" and "invert." The "invert" that I am speaking of is in reference to culverts and such. I have a good working definition of the terms, but I am curious about the technical definition as I...
I am working on mitigating housepads that were improperly constructed atop 15-20 feet of fill. Part of my recommendation was to remove several feet of soil, install a woven geotextile, and properly place and compact suitable fill material. Some of the "powers that be" at the site...
This is a real quick question:
I am evaluating a failure to a segmental block retaining wall. The backfill is reinforced with a geogrid. In one location behind the wall, a junction box (extending from ground surface down below the base of the wall) interrupts the geogrid reinforcement. The...
