Chapters

Chapter one:Introdution

Chapter two: architectural design

Chapter three: Inviromental design

Chapter four: Structural design

Chapter five: Internal system design


Chapter One : Introduction

A building lies in the western side of Nablus , this building consist of two stories of (8000 m2) , and height of each storey is (5m).

Ground floor consists of two main halls, library, cafeteria, bathrooms, and security and Theatre.

1st floor consists of computer hall, bathrooms, cafeteria , theare first floor.


Buildings of the project:

1-Building Main Halls

2-theater of the project

3-Central cafeteria

4-A major public library

5-Computer hall


The site with respect to palestine

Structural Design


Design Data

  • Yielding strength of steel, fy = 4200 kg/cm2.

  • Modulus of elasticity of steel, Es = 2.04x106 kg/cm2.

  • Modulus of elasticity of concrete, Ec = 15100 √ fc .

  • B300 → fc = 240 kg /cm2 → Ec = 2.34×105 Kg /cm2


Design Data

  • Unit weights of materials: Reinforced concrete = 2.5 ton/m3 . Blocks = 1.2 ton/m3 . Stone =2.6 ton/m3. Sand =2 ton/m3.

  • soil bearing capacity = 1.5kg/cm2 .


Design Data

Design loads:

live load is 500 kg/m2 =0.5 T/m2 for grond and first floor __ L.L For final roof=0.2 T/m2 .

Super imposed dead load is 0.3 T/m2 .

Slap thickness = 20 cm solid slap (roof)

Stair thickness =25 cm

Wall thickness = 20 cm


Theatre column center


Pannel beam roof reinforcement


Footing and tie beam for theatre


Structural Details for theatre


Theatre and cantiliever stairs


Structural analysis

laws and checking the results:

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.

first floor

Ground 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.


Design of beam

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

Use 22 Ø20 mm for the bottom

For 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

Shear wall reinforcement

Use 7 Ø16/ m Vertical Steel


Footing design:

After analysis on sap and finding load on footing per meter :

DL on Foundation = 40t/m

LL on Foundation = 20t/m

Section in footing


Column design

  • The design load can be calculated using the following equation:

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

  • 𝜙 = 0.65 for tied columns.

  • 𝜙 = 0.7 for spiral columns.

  • λ = 0.8 for tied columns.

  • λ = 0.85 for spiral columns.


Type of column


Service block (rib distribution)


Structural details for service block


Column centre and footing for service


Piles design


Chapter three

Nablus City Hall

Electrical Design


Lighting calculation

N=E*A/(n* FL*Ku*Km)

Where:

N=number of units in place(#of luminair).

E=Illuminance,measured by lux.

A=area of space.

n= number of lamp.

FL=Flux (lumen/lamp).

Ku=utilization factor (depend on room factor ).

Km=maintenance factor.


Sample of calculation


Calculation of the (MDB) and cross section area of cables

Total current for lighting = 80 A

We select diameter of cables

D cables = 25 mm


Total Current for sockets = 40 Amp and use cable with diammeter = 16 mm


Power for ground floor


Lighting for ground floor


Theatre (MDB)


Chapter four

Nablus City Hall

Mechanical Design


WATER SYSTEM

We use direct up feed system


We use cold water collecter

And hot water collecter

and electrical heater

Water distribution plan


Drainage system


Fire system


We Used (2) system in the project:

1- chilled water systym in the main hall. 2- gas to gas systym in the secondary hall.

FAN COILT

CHILLER 136 ton (Heat pump)327 GPM

We used air handler unit with capacity 8000 CFM


- Heating Load Calculation:


ACH=1.5

Required ventilation = 8 (L\s)\ person

#No Person= 900

Q Total=80 TON

NO diff = 100 we used (60x60) provide 400 CFM


Cooling load


Cooling calculation

Q total = 61.25 Kw

Q s= 43.10 Kw

V cir = 3591.71 L/S

V cir =7901.76 CFM

No . diffuser =100 use 100SIZE THE DIFFUSER FOR 400 CFM (60x60) CM


Difuser and grill for the building

Difuser and grill for theatre


ventelation

Use two type

Exhust fan window

Exhust duct grill


Chapter Five

Nablus City Hall

Inviromental Design


Inviromental analysis

تصنيف منطقة المشروع مناخياً:

تقع في المنطقة المناخية الثالثة وتقع بين خط طول شرقا ((35.370 وخط عرض (32.322) شمالاً


Design Condition


Sun Motion


Heat calculation

Calculate the thermal of the external wall


Calculate the thermal of the internal wall

Calculate the thermal of the ceiling


Sample of calculation

Heat loss for the All external and internal walls of the building (theatre ):

North wall:

Area wall = ((28.35+25.2+47+40.5+22.5+24+17.2+311.8+76.2)-(4+3)-(40)

= 540 m²

Area windows = 7 m²

Area door = 40 m²

Q(heat loss) = Σ Area × U × T

= [540 × 2.6 + 7 ×6.7+40×3.5]×[20] = 31818 watt.


materials

For external ceiling

For internal wall


Accostics


منطقة المرافق المحيطة بالمسرح ويكون فيها ضجيج عالي

منطقة المخازن المحيطة ويكون مستوى الضجيج فيها اقل

منطقة اللوبي والحركة الخارجية قريبا من المسرح ويكون مستوى الضوضاء فيها عالية اثناء وبعد العرض
