Structural Design

Yielding strength of steel, fy = 4200 kg/cmYielding strength of steel, fy = 4200 kg/cm22..

Modulus of elasticity of steel, Es = 2.04x106 Modulus of elasticity of steel, Es = 2.04x106 kg/cmkg/cm22..

Modulus of elasticity of concrete, Ec = 15100 √ Modulus of elasticity of concrete, Ec = 15100 √ fcfc. .

B300 → fc = 240 kg /cmB300 → fc = 240 kg /cm22 → Ec = 2.34×105 → Ec = 2.34×105 Kg /cmKg /cm22

Design Data

Unit weights of materials: Unit weights of materials: Reinforced concrete = 2.5 ton/m Reinforced concrete = 2.5 ton/m33 . . Blocks = 1.2 ton/m Blocks = 1.2 ton/m33 . . Stone =2.6 ton/m Stone =2.6 ton/m33.. Sand =2 ton/m Sand =2 ton/m33..

soil bearing capacity = 1.5kg/cmsoil bearing capacity = 1.5kg/cm22. .

Theatre Block

Service Block

In this block we use pannel beam system using solid slab 20 cm depth with continuos beams carried on shear wall.because of long spans and to achieve theatre function.

Ground floorfirst floor

Design steel for ground floor as the shear wall carry the load

Moment from sap (M=20t.m/m)

Design steel for first floor as the shear wall carry the

load

Moment from sap (M=20t.m/m)

Case 2:As another solution if there is compressive refile siolwith minnimum load 98% underground use 7 Ø12/ m in two direction upper and bottom steel use minnimum steel.

After design on sap and select beam dimension(120*80cm) approximetly each 4 m, the figure from sap show steel value as follow:

Design of beam

Use 22 Ø20 mm for the bottomFor the top steel use As minUse 12 Ø18

Use Ø10/20cm Stirups

Design for exterior wall:

From sap we find F11 = 14 t/m

Use 5 Ø12/ m Horizontal Steel

We find from sap F22 = 46t/m

Use 7 Ø16/ m Vertical Steel

Shear wall reinforcement

Footing design:After analysis on sap and finding load on footing per meter :DL on Foundation = 40t/mLL on Foundation = 20t/m

Section in footing

Column design

The design load can be calculated using the following equation:

Pd= Pn= *λ {0.85* fc(Ag-As) + As*f y}𝜙 𝜙.

𝜙 = 0.65 for tied columns. 𝜙 = 0.7 for spiral columns.

λ = 0.8 for tied columns.λ = 0.85 for spiral columns.
