    Moment Connection between Prestressed Spun Piles and RC Pilecap

    Hi, Is it possible for a connection between a prestressed spun pile embedded in RC pilecap to develop moment resistance? i.e. to be considered as a moment connection instead of pin connection? Anyone knows any literature or technical docs on this? Much appreciated Jackie

    Pile load test, ASTM vs BS

    I think it is to the benefit of the contractor to keep the reaction piles further from the test pile so that the stress bulb of the test pile and reaction piles will not overlap. In this way, the geotechnical capacity of the test pile will not be compromised by the reaction piles.

    Plate Bearing Test

    Hi, Plate bearing test applies load to the ground via a 300mm x 300mm steel plate. From the test, the load vs settlement and time vs settlement plots are given. From the plate bearing test, how to get: 1. Ultimate bearing capacity for an actual footing with a size much bigger than the steel...

    Speeding up the consolidation process

    JHeisenberg, what are the soil mixing techniques? Examples?

    Speeding up the consolidation process

    Looking at ways to quicken up the consolidation process of a 20ha land overlain with very soft clay and sand layers with SPN less than 10. Any novel ideas? I know the conventional way is adding surcharge and installing vertical drains. Any faster way?

    Steel Roller

    Just wondering if there is any off the shelf unit that I can purchase which might be cheaper/faster compared to fabricating it.

    Steel Roller

    Hi I am looking for a steel roller, like the pic attached, to support a lightweight steel bridge carrying pipes. Any idea what this is called and any manufacturers for this? http://files.engineering.com/getfile.aspx?folder=86df94c0-59a2-414f-91c5-07c366a8d488&file=20171012_102629_resized_1.jpg

    Immediate and Consolidation Settlement

    I was told that the 'mv' value from the oedometer 1-D consolidation includes the elastic, i.e. immediate settlement. Hence, the total settlement is given by the change in stress x mv x height of soil layer. There is no need to add the immediate settlement, which is a function of the load...

    Undisturbed Samples

    Anyone has any idea how to collect undisturbed clay samples for the lab 1-D consolidation test? I was told by the soil investigation team that they could only collect undisturbed samples up to SPT-N = 4 using the hydraulic method. For higher SPT values, they could use the Mazier Core Barrel...

    Correlation between SPT and Clay Properties

    Hi Anyone has the Stroud (1974) and Stroud and Butler (1975) papers on the correlation between SPT and undrained shear strength and volume of compressibility? Stroud (1974) The standard penetration test in insensitive clays and soft rocks Stroud and Butler (1975) The standard penetration test...
