Project description:

NBC project is located in Ramallah city and it is used as warehouse, it consists of four stories .The first and second stories are 7.8 m high and the last two are 3.9 m .

Each story has an area of 3000 m2

. The basement story used for coca cola production and other beverages the ground story is a warehouse for the packages and the first and second floors used as offices.

Design code:

ACI 318-08 (American concrete institute), is the building code adopted in this project for the design of structural elements.

IBC 2006 for seismic design

How to find the live load? To find live load take the dimension of coca cola product and the weight Make this value as a weight per cubic meterFind the storing height for this productFind live load per square meter

What structural system to select?

Take a test frame and analyze it using sap2000 v14To find which the most economic structural system and analyze all the project with this system

Frame to be testedIn the stores :

Frame to be tested in the offices:

Analyze and design the frame in the stores as a waffle slab

:and find the following dataVolume of concrete =52.3cubic meterWeight of steel =5.52ton Analyze and design the frame in the office as a waffle slab

:And find the following data Volume of concrete=30cubic meterWeight of steel=1.8ton

Waffle slab:

Solid slab:

Analyze and design the frame in the stores as a solid slab

:and find the following dataVolume of concrete =70.54cubic meter Weight of steel =4.9ton Analyze and design the frame in the office as a solid slab

:And find the following data Volume of concrete=45cubic meter Weight of steel=3.1 ton

Ribbed slab:

Analyze and design the frame in the stores as a ribbed slab

:and find the following dataVolume of concrete =50.73cubic meterWeight of steel =4.85tonBlock=26.46 cubic meter Analyze and design the frame in the office as a ribbed slab

:And find the following data Volume of concrete=41.3Weight of steel=2.78tonBlock=915 piece

Why solid slab?From the results the most economic material is waffle slab but the productivity of conduct formwork of waffle and ribbed slab is very height so the total work cost of solid slab is more economic so that the project designed as a solid slab

3D modeling: Divide the total project into three section to make it more regular shape for seismic design by making structural divide

Do the 3-D design for the overall project as a solid slab

Project plane:

Design of slabsUsing 3-d analysis by sap to analyze and

design slabs in the three partsFind column strip and middle strip and find

moment per meter to find area of steel

Deflection chickMaximum permissible deflection =52.92mm

From deflection shape from sap max. def.=38.33 ok

Stress-strain relationship

From previous frame Mu=1729kn/m

From sapMu=172

%of error =0.16% ok

Equilibrium checkFrom hand calculation maximum

load=229691knFrom sap=229676kn

%of error =0.06%

Design of column

Using p-delta analysis because the length of column =7.8m and slender column may occurs For economical design use maximum steel ratio =0.01% Stirrup distribute according IBC-code for seismic design

Design of footing

Why mat foundation:Because the basement floor used to carry high load and machine it necessary to make a another slab for machine because of it and for economy use mat foundation

Design of mat foundation

The same as two way solid slab

Mat foundation
