I am trying to get the effective strength parameter for clay. If I know the SPT number and undrained cohesion Cu for a normally consolidated clay, how to get the effective phi for this clay? Any reference? Thank you very much.
In concrete structure member design, is the ultimate srtength equal to the norminal strength or the norminal strength times the strength reduction factor (phi)? For example, ultimate P = Pn or (phi)*Pn? ultimate M = Mn or (phi)*Pn? Thank you very much.
I am trying to model the rip-rap/rockfill using a finite element procedure. Please advise some reference books or papers for the typical engineering properties, such as young's modulus, friction angle, poisson's ratio. Thank you.
I am trying to model the rip-rap using a finite procedure. Where can I find the typical parameters for rockfills. Please paste some references. Thanks a lot.
I am doing an elastic stress analysis for a rectangular uniform surface loading on semi-infinite area. The formulus are on P54 of "Elastic Solution for Soil and Rock Mechanics" by H. G. Poulos and E. H. Davis (1973). The normal stresses of Eqns 3.18a~c are not dependent on Poisson's Ratio (They...
Where can I find some reference/typical values of E for soil using Mohr-Coulomb Model in finite element analysis (such as values for loose, midium, dense sand, or soft, stiff clay?) Thank you in advance.
Any other requirements in determining the laterally loaded pile or caisson's tip elevation except considering the lateral deflection at pile cap and pile capacity? Are there any requirements for the lateral deflection shape around pile tip or moment diagram shape around pile tip? Thank you very...
Hi, everyone,
How to evaluate the effective strength parameters (phi & c) of clay material from the given undrained shear strength (cu)? Sure, the SPT N values are also available. How to estimate k0 at rest? And any reference books or papers? Thank you.
How to evaluate the stiffness EI of a composite beam (like W24 encased inside a 36 in diameter 4000 psi concrete) considering the craking effect in concrete? Thank you very much.
