I'm asking you to direct me to which you consider as being the most valuable structural steel design textbook. I've read many reviews, but up to now I wasn't able to arrive to a comfortable decision. Please advise regarding this matter.
Best regards.

Actually your right, the ER delivered by a particular SPT setup depends primarily on the type of hammer and anvil in the drilling system and on the method of hammer release. An energy ratio, ERm, of 60% has generally been accepted as the reference value. But basically, approximate correction...
Regards converting N-value from shear wave velocity, does anybody has the relationship between N-value and Vs (shear wave velocity). Not only for sand, because I have those ones.
The best way to write software for engineering remains the traditional way, which means Fortran. (AbSoft produce a very powerful compilator for both fortran77 and 90). Don't worry about graphical interface, you could design it in VC++. You could link the two codes (C and Fortran) very easily...
Your question is still blur,
Anyway N-value gives data for soil index properties based on Standard penetration test, which is made under well-defined conditions such as 140-pound hammer dropping 30 inches in free fall. If don't have some maps or equations for establishing a relationship between...
I have to agree with qshake, any of us has to be able to write some code and beside that any of the FEA programs users must understand what's going on behind the screen. Using a program as a black box gives you a lot of uncertainties. That's why I recommend to anyone who has the opportunity to...
The so-called Chinese criteria, as defined by Seed and Idriss (1982), stipulate that liquefaction can only occur if all three of the following conditions are met:
(1) The clay content (particles smaller than 5micro) is less than 15 percent, by weight.
(2) The liquid limit is less than 35%...
Is there anyone who had used the German DIN 4227? Actually I need some links for some documetation for concrete creep. My problem is, in fact, that the german norms (DIN 4227) give no analithical equation for concrete creep. The Eurocode 2 (which is based on DIN 1045-1) define a formula for...
i have to do a study about soil liquefaction, and within that work I need to use the so called chinese criteria. is there someone who actually used these criteria. As a matter of fact my question is What could be the mmeaning of "liquid limit". I guess that's a common term, frequently...
