INTRODUCTIONo The project is a multi- storey building which is used for residential purpose as hotelo It consists of 6 stories (basement, ground.1st.2nd,3rd,4th,5th floors),o The basement which is 3m height use as store, o The ground floor which is 4m height use as reception and servicing ,o The other floors which is 3m height in this hotel use as sleep rooms for guests and

passengers.

OBJECTIVES

• Analysis and design of multi-story building including slabs,beams,columns,elevated wall and foundation.

1. Analysis and design of slab supported with beams by Direct design method and yield line method for cantilever and corner span.

2 . Analysis and design of beams by coeffi cient method.

3 . Analysis and design of columns and elevated wall.

4 . Analysis and design of foundation.

STRUCTURAL ELEMENTS

Slab Beam Column Foundation Elevated wall

TYPES OF SLAB

Slab

Two-way beam supported slab is our beam type

SLAB DESIGN

• Analysis and design by direct design method and yield line method for cantilever and corner panel.

• For the most critical span

Max -ve M @long dir = 18.17 kN.m

Max +ve M @long dir = 14.8 KN.m

Max -ve M @short dir = 5.835 kN.m

Max +ve M @short dir = 4.75 kN.m

BEAM

• Analysis and design by coefficient method (aci code 318-08.8.3.3)

• For the most critical beam

Max +ve M= 107.23 KN.m

Max -ve M= 145.15 KN.m

SOME ADDITIONAL WORKSCOMPUTER PROGRAMING

Analysis and design the exist slab and beam by sta4-cad v13 and staad-pro v8i

Note// this programing steps doesn’t included in our graduation projectWe just did it for more assurance that has been calculated by hand.

STAD4-CAD V13

Is a program which is used for analysisAnd design reinforced concrete structures

By direct design Max M long dir = 18.17 kN.m Max M short dir = 5.835 kN.m

By stad4-cad program Max M long dir = 19.71 kN.m Max M short dir = 6.58 kN.m

DETAIL OF SLAB BY STA4-CAD

STAAD.PRO V8

It is a program which is used for analysis and design of reinforced concrete structures

By coefficient method aci code 318-08.8.3.3

Max +ve M= 107.23 KN.m

Max -ve M= 145.15 KN.m

By stad pro program:

Max +ve M= 82.54 KN.m

Max –ve M= 130.97 KN.m
