The
beams receive loads from the slabs automatically.
This process is performed by the program. In
addition to any wall loads on the beams, any other
additional distributed loads can be defined on
beams as dead or live loads. The program takes the
elevation of the beam upper surface from the
elevation of the story defined on the story
settings part as default elevation. If the beam is
inclined (in vertical direction) and/or inverse
beam, this state is defined by giving additional
information to the left and right end elevations
of the beam. The cross-sectional properties of the
beams are determined by the program automatically
depending on the story slab system. If the beam is
not fixed to any slab, it is assumed as having a
rectangular cross-section shape. But in case of
any slab on the right or left side of the beam, it
is deemed as full or half T-beam. Effective width
of slab for T-beams is determined in accordance
with the relevant codes. The cross-sectional
surface area and the moment of inertia of the beam
is calculated automatically. However, for the
general frame analysis or for the renovation,
restoration and reinforcing projects, the user is
enabled to modify arbitrarily the cross-sectional
surface area and the moment of inertia of the beam
as he wants.
The
torsional rigidity of beams can also be intervened
like the torsional rigidity of columns. If zero is
entered, it means that the torsional rigidities of
beams are neglected.
After
shear forces and bending moments are calculated
for all loading cases, reinforcements are assigned
to both ends and to the span of every bar by
considering the most critical load combination in
the ultimate power method. In beams, the
reinforcements are assigned according to monoaxial
bending. The minimum and maximum reinforcement
provisions are especially investigated. |
