    Any Correlation for Cohesion

    FireChch thank you for your answer. After all your answers i decided to do as you say. The building we are speaking is 12m x 22m After we speak i did calculations like you told me and i am more conservative i guess so i get phi of 16 degrees(phi'=2/3phi) and for c i took a very little value...

    Any Correlation for Cohesion

    suhb PMT Thank you for your answer i am already using it for mv and su (Cu) and as FireChch told it's for undrained shear strength. I am looking for drained cohesion for long term bearing capacitcy. In normal cases i would go with Φu=0 and Cu= Something (From that graph with Plasticity Index f1...

    Any Correlation for Cohesion

    Thank you all for your answers. I knew that designing a footing for ultimate bearing capacity is Illogical. I need approval of "city hall" and they have a form that suggests to calculate ultimate bearing capacity. That's why i needed "c" value for. GeoEnvGuy thanks for that manual. Almost every...

    Any Correlation for Cohesion

    Thank you for your answer fattdad. I am really sorry about my english in advance. I know that they are not same thing. Sometimes there is no lab experiment for clay's cohesion. (To use in vesic's bearing capacity as follows: In my country you cannot say to some people "Run some tests for clay"...

    Any Correlation for Cohesion

    I have too many charts and tables for Undrained Shear Strength. I couldn't find any source for cohesion value for clays. Is there any Direct correlation beetwen cu (Undrained Shear Strength) and c (Cohesion)or any information about cohesion table (or charts, graph... etc) In my boring logs and...

    Settlement on Clay

    If you have any further information about the "clay" like Plasticity Index and SPT-N values you can use Modulus of Volum Compressibility with: consolidation s = coefficient of compressibility x average stress increase through layer x layer thickness as maxim22 suggests. (Note: Don't forget to...
