Buildings’ Elements Beam(RB) Beam(B) Ground Beam(GB) Roof Column(C) Slab(S) Footing(F)
3. Overview Structural Systems • Truss • Beam&Column, Rigid Frame • Bearing wall • Floor Systems • Lateral Load Systems
A. Truss Hinge joint Comp. Tens. • Plane Truss • Space Truss 2-D 3-D
D. Floor Systems • What is slab? • How to consider? • Look at the 4 next pages before going to theory….
TYPE OF FLOOR SYSTEMS • It can be classified in different ways: • By Material Used • By Structural action of the slab • By Method of construction
By Material Used • Floor slab : Reinforced concrete, Timber, steel, brick • Beam or Girder : Reinforced concrete, Timber, steel
By Structural action of the slab • Bearing slab (Slab on ground) • One way slab • Two way slab • Joist slab, Waffle slab • Flat Slab • Irregular slab
By Method of construction • Cast in situ concrete Slab and Beam • Precast concrete slab….on Beam… • Precast beam and slab • Precast slab on steel beam
Factors for Design and Cons. • Load… LL., DL., FL. • Span • Thickness • Deflection and Vibration • Stiffness • Methods….
Comparison for slabs • Timber Slab • Steel Slab • Concrete Slab • Details in class
