Your slab design may require more flexural bars or they may already be there to meet other slab design requirements. Podium slab construction methods - The podium slabs are built up with the construction procedures given below : • Post-tensions cast in place construction method • Precast hollow core; this construction method is mostly recognized as it offers rapid safe working platform and outstanding construction speed. These slabs offer high fire ratings, reduced sound transmission, as well as reduced vibrations between living areas. Load bearing elements such as walls and columns of superstructure above the podium slab may not align with substructure load bearing elements below. The upper slab of the concrete podium typically acts as both a fire separation and structural transfer slab for the framing above. Because the International Building Code (IBC) treats podium-style buildings as two separate structures built one on top of the other, this design boosts the number of potential stories you can build. Single-Family In most cases, the Hollow-core floor is able to clear span from foundation wall to foundation wall allowing interior columns or bearing walls in the basement to be removed. The Beam system affects the laying path of plumbing line and conduit, which limit its demand. Look to ASCE 7 and IBC for when a slab may be assumed as fully rigid versus semi-rigid.- _____ Q: How are point loads from the ends of the ends of the beams beign taken down? This design example uses the term “podium slab” which, while not included in the 2006 International Building Code (IBC) or 2007 California Building Code (CBC), is commonly used in the building industry. You just need to design the slab for the different stages of loading. Our job is to build the concrete portion and the most difficult part of that is the transfer slab that will take the load of the wood structure.
