9. Materials: • None structural materials: • Blocks • Plaster • Tiles • Filling materials under tiles • Masonry stones.

10. Loads: • Live loads: (L.L) = 4.8 KN/m² ……………. Table 16_A in (UBC97) • Dead load includes : Own weight. Super imposed = 4 KN/m²(on slab 32cm) Super imposed = 5 KN/m²(on slab 25cm) • Seismic loads: Design parameter uses as follow: • Seismic zone factor (Z)=0.15 • Soil type Sc : very dense soil • The important factor (I)=1 • The factor Ca=0.18 • The factor Cv=0.25 • The response modification factor R=5.5 (intermediate frames)

12. Codes and standard • ACI - 318 – 08 • UBC- 97 • IBC -2009

21. 3D – Structural Analysis and Design

22. Compatibility

23. Check equilibrium:

24. Check equilibrium: • Dead loads %Error = • live load = 10607.89 KN %Error = 0% ok

25. Design of slabs as 3D • Ribs is designed by taking results from sap • Representative Sample of ribs is designed • Basement floor two sample. • Ground floor three sample. • First floor three sample. • Modification factors is used

26. Slab modification factors for slab 32 cm,25cm.

27. Moment diagram M11 (Basement):

28. Moment diagram M11 (Ground floor):

29. Moment diagram M11 (First floor):

30. Moment diagram M11 (Whole building):

31. Design of beams: Beams are classified into three types:- • Hidden beams , with depth equal to the slab depth • Drop beams, with depth greater than the slab depth. • Tie beams used at ground level.

32. Design of beams • Beams section: B40*32, B40*40, B40*55, B40*60, B40*70, B40*80, B40*90, B40*100 • Beams modification factor: Moment of inertia 2-axise =0.35 Moment of inertia 3-axise =0.35
