design a 15 story tower with very large area of low rised shopping area (5 story).
if running in a modal response method, do i need to worry about lower area with different period (much less)?
right now the Tx=2s is governed by the tall tower i believe.
for example, if i remove the tower...
This is a conceptual question.
An existing 4 level concrete building to have 1 level added transfer steel frame and 3 level added timber structures. there is a rigid slab at steel transfer frame level.
As you know it is not possible to model timber building in Etabs.
I thought a implication...
Hi Kootk,
Yes, i just do bolted one with an end plate. The simple shear connection requires 7 bolts and two L plates, as end plate moment connection just eight bolts and a big plate. Really don't think there are any different.
And in actual building shape, the rectangular slab is a little bit...
It is a 7 story building. I did run a dynamic response spectrum analysis on this building, and turns out only the shear core has the big reactions, all moment frame only has very little shear force...
I would just keep moment frames and play around the number to make them work. It is just...
Hi Guys.
I have a question on shear force distribution to a steel framed building with concrete shear core.
The shear core is not at the centre of the rectangular slab. So the building has some torque. I put a number of moment frame and trying to balance the torque.
is there any simple hand...
