    Synthetic Site Specific Seismic

    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...

    shrink/swell potential of shales

    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?

    Dynamic Penetrometer (DPH) conversion

    The client prohibits us divulging the exact location but that the site is in Eastern Europe and the equipment seems to be a relatively common beast in Northern Europe Germany. We are using Italian GeoStru geotechnical software to analyze this and are trying to make sense of the computations...

    Dynamic Penetrometer (DPH) conversion

    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?

    Seismic Site Class - Shot rock fill

    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...

    610 Limestone

    610 is a local spec (not an astm specification) for the south/southeastern united states. i have recently run across the "standard" gradation for this material and can provide it to you should you need it. Thanks for the responses.

    MORTAR CUBES compressive strength, asap please

    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...

    Request for info

    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...

    Definitions

    I apologize for not clearing this up. The "Right of Way" that I speak of is in the context of roadway design, etc... Thanks for your help

    Definitions

    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...

    Nonwoven geotextile reinforcement

    I appreciate the input. For whatever reason (cost, i'm sure) no one was called to verify compaction of the fill during original construction. Now, for the same reason, the "powers that be" do not want to remove and properly replace the uncontrolled fill (which was my original...

    Nonwoven geotextile reinforcement

    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...

    hydrostatic pressure

    First of all, I thank everyone for all of their input and advice. Focht3: the answer to your questions are difficult to answer as I only have photographs of the site. Remediation has already been completed.
