    What's preventing the LT buckling on the 10m glass fins of Apple store 5th Avenue ?

    I was thinking about this recently, I see no lateral bracings on the glass fins. My hypothesis is that the glass façade itself is acting as a lateral bracing for the glass fins. Is my hypothesis correct? Can someone decode the secret behind this structure for the rest of us?

    Why does some structural engineers disapprove Mindlin's Plate theory for the analysis of Laminated Glass

    I was going through this forum and learned that there are many structural engineers here saying that Mindlin's Plate theory is outdated, not accurate for the analysis of laminated glass. I've seen that SJ Mepla uses this theory to predict the behavior. I was wondering what are the issues or...

    Stress around circular hole

    Hello Guys, I have a bracket with a hole and when I perform FEM analysis i get stress concentration around the hole. My question is can I use plastic stress field around the hole? And if i'm using plastic stress , to which value I will compare ? Do we have a code or standard reference stating...

    Curtain Walls/Facades

    Dear Engineers/Scientists, When you design the double skin ventilated facade system, what all loads are coming on the interior glass? Does the 'chimney effect' takes place in the internal glass panel? or the wind load will be negligible only? How do you arrive at exact wind load on the internal...

    Strand7 Python integration

    Thanks for the reply guys. @ Erik say for example, I have a finite element model of a steel bracket with 4 anchor bolts and I need to play with the anchor bolt spacing so that I need to get a minimum stress. So if i do it manually it is too much time-consuming. Is there a way that i can write a...

    finite element methods

    Thanks GregLocock for the replay! Im doing masters in Structural engineering and final year thesis in aerospace engineering (using CFD,ALE coupling) now only I fell In love with finite element methods. Could you please suggest me some pdf/ebooks to start fem programming using matlab,For beginner.

    finite element methods

    Hii all Im new to this forum. I have certain doubts regarding fem. 1.Why scientists use programming in fem using fortran/phython/matlab when we are having advanced softwares? 2.what is explicit finite element and extended fem?
