Good Morning,
Does anyone have experience designing a folded stair in timber? Is it doable?
See attached picture for reference

Hi,
I would appreciate if someone can help me understand the auto-lateral loads for earthquake that etabs generates.
In the auto-lateral load, I input all the seismic coefficients and factors. For the direction of the load, can i select both X & Y? or do i have to create a different load...
Good morning guys,
I have done a response spectrum analysis to a 16-story building and I got that my dynamic base shear is bigger than my static base shear. Since i don't need to scale up my dynamic base shear as per asce7 12.9.4, can i instead scale it down?? not to an 85% but to a 100%...
Hello,
I'm doing the structural evaluation of a 3-story building that has in one direction only confined masonry. For earthquake loads the building doesn't comply with any requirement and we are adding concrete shear walls. During the evaluation I used an R factor of 3 but now that I have added...
Hi guys,
I have a quick question regarding shear studs for composite beams, I have specified studs to comply with Astm A108 (fy=50ksi, fu=60 ksi). The contractor wants to use A307 or A325 for shear connector, I know that A325 are not allowed to be welded.
Can we use A307 bolts as shear studs...
Hi all,
I would like to know where i can locate the lap splices for special shear walls. I know that for columns the splices are allowed only on the middle height of the column, how about rc walls??
Thanks in advanced

Hi, i am trying to design a timber truss. I have applied dead, live and wind loads.
The wind loads were not generated using staad, instead I created a load case type
wind and input there the wind loads.
After that i created the combination loads and designed the truss members.
I have noticed...
Hi guys, any of you have an idea of designing a staircase like the one shown in this website (the last one - ortopoligonales)?

i have many doubts about the reinforcement, does it work? please if u have any detail please send it to me.
thanks a lot
