Floor Systems And Horizontal Elements(E-learning and Reading Modules) -Floor systems are the horizontal planes that must support both live loads(people,funishings and movable equipment) and dead loads(the weight of the floor construction itself). -Floor systems must transfer their loads horizontally across space to either beams and columns or to loadbearing walls. -A floor system may be composed of a series of linear beams and joists overlaid with a plane of sheathing or decking or consist of a nearly homogenous slab of reinforced concrete.The depth of a floor system is related directly to the size and proportion of the structural bays it must span and the strength of the materials used. Concrete floor -Cast in place concrete floor slabs are classified according to their span and cast form -Precast concrete planks may be supported by beams or loadbearing walls.
Steel Floor -Steel beams support steel decking or precast concrete planks -Beams may be supported by girders,columns,or loadbearing walls. -Beam framing is typically an integral part of a steel skeleton frame system -Closely spaced light gauge or open web joists may be supported by beams or loadbearing walls -Steel decking or wood planks have relatively short spans -Joists have limited overhang potential
