Example 1 (Reinforced Concrete Building) (MODELLING) Using the concept of auto-generation method of STAAD. Pro V8i software, sketch and construct the idealization numbering of joints and members concrete structure shown below (All dimensions unit in meters). Edit the commands for the modeling of the reinforced concrete structure shown below: ( x- 3bays @ 4m, y- 2story @ 3m, z- 3bay @ 5m) Note: Ec = 3200 kip/in2, Density = 2500kg/m3 circular column section (Radius = 20cm), interior beam size (T-section) [flange bf = 80cm, tf=15cm], [web H = 60cm, bw = 30cm], edge beam size (30*50), roof and floor slab thickness = 15cm. external and internal support (fixed), corner support hinge.

Example 1 (LOADING, ANALYSIS and DESIGN) Using STAAD-Pro V8i software, analysis and design concrete structure shown according to load combination for the cases: 1. Self-weight load with factor of safety (F.S. =1.2) 2. External loads shown in figure with (F.S.=1.6) 3. External distributed load (4kN/m2) for floor slab and (5kN/m2) for roof slab with (F.S.=1.4) 12kN/m
