Permitted the core shear walls to resist the full shear forces base
without the participation frames How do you explain it
given the code in the event of share normal frames (ordinary
frames) To resist earthquakes with walls.
5. 5
It can be allowed to Core and shear walls full base shear force
resistance without the participation frame
Questions and analysis (1)
How can programs by blocking columns frames participation
To resist the base shear forces and keep the share rigidity
Determine the center of rigidity (CR) and central (e) the
determination of torsion (torsion)
2. Question Analysis (2)
In theory and on paper and the use of the programs has been
blocking share of frames
To resist earthquakes and entrusted to the Core and walls shear
full Seismic resistance.
-How, in fact, and when the actual the earthquake struck
Slab as we know works (Diaphragm) solid columns and will give
its share to resist earthquakes with walls according to the
stiffness
- How else can you explain this once involved in
determining the frame stiffness Center
And the determination of the amount of a centralized torsion
6. 6
At the same time we want not to participate in the resistance
base shear force.
-How do you explain and explain it
Of course this is true explanation the building will not collapse if
the walls Able alone to withstand the forces on the building
-- I mean, you can choose the items you want designed and
calculate To resist the full base shear forces of
- The other elements are present weight and stiffness butWill
not participate in resisting the horizontal forces because the
cross section and steel Not calculated and designed so
-- So we can give some of the elements in the
resistance Horizontal and base shear forces
That was the frame or walls, but we must takeInto
account effect of their presence even if it did not
participate in the resistance
This is the explanation and answer to some
colleagues How get out an element of resistance and
keep the stiffness
- We do not get out the presence of any element
7. 7
But not designed or calculated to participate or to resist
any Horizontal forces of from the base shear
