For
the load analysis, any vertical and horizontal
loads are considered. The vertical loads are
composed of the dead load of the building, the
cladding and coating loads, wall loads, any
additional point loads on beams, columns and
slabs, and line loads on slabs as well as any
extra live loads defined on beams.
The
loads acting along the bar axes and the inverse
signs of the fixed-end effects of the point loads
acting at span are expected as external loads
acting on the joint.
The
loads transferred to beams from slabs are the
support reactions of finite elements. For this
reason, the shape of the load is not triangle,
trapezoid or rectangle. They can be in any shape,
or can be expressed in any function. Furthermore,
the point and/or line loads defined on slabs are
also transferred to beams as vertical loads.
The
loads transferred from ribbed and/or waffle slabs
to beams, are the support reactions of the ribs on
the respective frame beam. In the program,
however, the ribs of the ribbed slab or waffle
slab system can also be defined as a separate beam
objects. In this case each rib is entered as a
separate beam and each slab piece between the ribs
as a separate floor slab. If 3D analysis is made,
the program solves the system as a whole. In this
case, however, the support reactions or the shear
forces of the ribs are not transferred as a load
to the frame beams, and the frame beams and ribs
will take with the 3D analysis exactly so much
internal forces as being proportional to their
rigidity degrees. |
