Hi all,
To test out a FEA software, I modeled a cantilever beam 6m long and 0.7m deep with a concentrated load at the tip of the beam. I compared the stresses at the support from FEA to those obtained by simple bending theory (Euler-Bernoulli), I got a difference of about 15% (FEA is larger)...
Hey guys,
I am just wondering what load combinations am I supposed to be using when conducting a non-linear cracked analysis for determination of immediate and long term deflections on SAFE 14?
I added 6 load cases, Dead-Immediate (Cracked), SDL-Immediate (Cracked), Live-Immediate (Cracked)...
Hello everyone,
I have seen in the SAFE 14 manual that they use an equation for the depth of the compression block in concrete according to AS 8.1.2.2, I could not find the equation in the code, and I tried to get at it without much luck. The equation is a = d - sqrt(d^2-(2M*/0.85f'c*phi*b))

Hi all,
I have a three-span continuous bridge. I am undertaking a project which involves comparing the live load distribution factors obtained by AASHTO LRFD formulas to the distribution factors obtained by finite element analysis. I have obtained the distribution factors from LRFD, and I have...
Hi all,
Just a quick question, when you guys read a book to enhance your knowledge, do you read the whole book from start to finish or pick and choose what you wanna read? Or any techniques you guys use to get the most out of your reading?
Cheers
Hello,
I have used Strand7 to model a simple span I-girder bridge using plate elements for deck and beam elements for the girders with centroids of both coinciding. I am getting good results for analysis of bridge under dead load however when I add a truck load, I get very different results...
