Outline: Project description Design code How to find the live load What structural system to select Why solid slab 3 Dmodeling Design of slabs Design of column Mat foundation

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 m 2. 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 meter Find the storing height for this product Find live load per square meter

What structural system to select? Take a test frame and analyze it using sap 2000 v 14 To find which the most economic structural system and analyze all the project with this system Frame to be tested In the stores:

Frame to be tested in the offices:

Waffle slab: Analyze and design the frame in the stores as a waffle slab and find the following data: Volume of concrete =52. 3 cubic meter Weight of steel =5. 52 ton Analyze and design the frame in the office as a waffle slab And find the following data : Volume of concrete=30 cubic meter Weight of steel=1. 8 ton

Solid slab: Analyze and design the frame in the stores as a solid slab and find the following data: Volume of concrete =70. 54 cubic meter Weight of steel =4. 9 ton Analyze and design the frame in the office as a solid slab And find the following data : Volume of concrete=45 cubic 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 data: Volume of concrete =50. 73 cubic meter Weight of steel =4. 85 ton Block=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. 3 Weight of steel=2. 78 ton Block=915 piece

Slab type Waffle slab Solid slab Ribbed slab story stores office Volume of concrete 52. 3 30 70. 54 45 50. 73 41. 3 Weight of steel 5. 52 1. 8 4. 9 3. 1 4. 85 2. 78 block - - 26. 46 cm 915 peice

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

3 D 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 slabs Using 3 -d analysis by sap to analyze and design slabs � in the three parts Find column strip and middle strip and find moment � per meter to find area of steel

Deflection chick Maximum permissible deflection =52. 92 mm � From deflection shape from sap max. def. =38. 33 ok �

Stress-strain relationship

From previous frame Mu=1729 kn/m From sap Mu=172 % of error =0. 16% ok

Equilibrium check From hand calculation maximum load=229691 kn � From sap=229676 kn � % of error =0. 06% �

Design of column Using p-delta analysis because the length of column =7. 8 m 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
