BPC Group has a long range of standardized
products. Please refer to our products sections for more information on
individual products. The wide choice of individual products and
combination of them make any cast-in-situ project viable in Precast
building system.
The Precast Building system is designed to emulated cast-in-situ
structure. The gravity load is transferred to the foundation through
column/beam/slab joints, as is the case with traditional buildings. All
the joints are essentially modeled as pinned joint.
The horizontal de-stabilizing forces due to eccentric gravity load,
wind load or seismic load are transferred to shear wall made up around
lift shafts, staircases well or freestanding walls. Either the
stabilizing wall could be cast-in-situ wall or Precast concrete wall
join together. Normally the cores of Hollowcore slabs are opened up and
connected together with beams/ panels by providing r/f, before they are
grouted together. |
The second option could be that the screed on top
of the slab can be mobilized to act as horizontal diaphragm once it is
connected correctly with Hollowcore slab and Beam. The type and
quantity of material will depend on the induce forces and shape of
building. If the building is short and stout it can be that all the
above details may not be necessary. And the frictional forces between
different elements can be adequate. However, local engineering laws are
to be respected in all such cases.
