• MATERIAL COST : CONCRETE & STEEL

• SCHEDULE OF QUANTITIES

METHODOLOGY• PRELIMINARY DESIGN OPTION 1 & 2

• PERMEANT ACTION

• EQUIVALENT STATIC HORIZONTAL FORCE FOR EACH LEVEL

• DESIGN BEAM , COLUMN AND FLOOR

• COST ESTIMATE

• THE FINAL DESIGN

CONCRETE OPTION 1• PRELIMINARY DIMENSION

• PERMANENT ACTIONS

• SEISMIC WEIGHT

• WT = W1 + W2

• =360.49 + 279.62

• = 640.12 KN

DEFLECTION • DEFLECTION BY MULTIFRAME

• PERIOD OF VIBRATION BY RAYLEIGH METHOD

• EQUIVALENT STATIC HORIZONTAL FORCE FOR EACH LEVEL

D2= 7.087 MM = 0.007M

D1= 4.956 MM = 0.004M

STRUCTURAL ANALYSIS

DESIGN BEAM • DESIGN FOR BOTH LEVELS

• COMPRESSION AND TENSION ZONE

• AREA OF REINFORCEMENT AS=T

FY

• BARS= 3 D10 @ 40MM

• CHECK M* CAP= T. JD

DESIGN BEAM • P MIN ≤ P EFFECTIVENESS ≤ P MAX √

• SHEAR REINFORCED REQUIRED

• AV=AREA OF SHEAR REINFORCEMENT

• 2 LEGGED 10 MM STIRRUPS

• METHODOLOGY AND CALCULATION USED FOR BOTH TRANSVERSE & LONGITUDINAL SECTION

DESIGN COLUMN

DESIGN COLUMN• MAX M* & CORRESPONDING N*

• USING COLUMN DESIGN CHART

• FINDING PT FORM 0.7 AND 0.8 CHARTS

• GROSS AREA OF SECTION

• AG= PT X AS

• 4 D16 BARS

DESIGN COLUMN• P MIN ≤ P EFFECTIVENESS ≤ P MAX √

• SHEAR REINFORCED REQUIRED

• AV=AREA OF SHEAR REINFORCEMENT

• R10 @ 150 C/C

• METHODOLOGY AND CALCULATION USED FOR BOTH TRANSVERSE & LONGITUDINAL SECTION

DESIGN FOR SLAB FOR BOTH

OPTION • FROM PRELIMINARY DESIGN

• TWO WAY SLAB WITH EDGE OF BEAM TABLE 2.2 NZ 3101 2006

• BENDING MOMENTS FROM

• 1.2 G +1.5 Q BOTH LEVELS

• M*X &M*Y = B WU LX2

• BX AND BY TALBE C 6.2

DESIGN OF SLAB• NO OF BAR = AS REQ

• AS DIA

• 7 HD12 @ 150MM PER 1 M

• TERMINATION POINTS 0.15 LN

• ACCORDING TO STANDARD

STEEL OPTION 2

• PRELIMINARY DIMENSION

COLUMN 310 UC158

BEAM 250UB37.3

• PERMANENT ACTIONS

• SEISMIC WEIGHT

• WT = W1 + W2

• =302.19 + 243.03

• = 545.22 KN

STEEL • DEFLECTION BY MULTIFRAME

• PERIOD OF VIBRATION BY RAYLEIGH METHOD

• EQUIVALENT STATIC HORIZONTAL FORCE FOR EACH LEVEL

D2= 0.558 MM

D1= 0.295 MM

STRUCTURAL ANALYSIS

BEAM 250UB37.3

• ULTIMATE AND SERVICEABILITY LIMIT STATES

• SECTION & MEMBER AND SHEAR CAPACITY

• NZS 3404 1999

• BENDING MOVEMENT M*X AND M*Y

• CALCULATE ᶿM*

• MEMBER * M CAPACITY ≤ SECTION M* CAPACITY

COLUMN 310 UC158

• SECTION & MEMBER CAPACITY

• AXIAL COMPRESSION & TENSION

• N* ≤ N ᶿ S

• N* ≤ Nᶿ C

SCHEDULE OF QUANTITIES FOR BOTH

CONCRETE & STEEL• COSTS WERE TAKEN FROM RAWLINSON'S

NZ CONSTRUCTION HAND BOOK 2001

• ALL PRICE INCLUDED SUPPLY , DELIVERY , PLACING AND FIXING AND LABOURS

• COMPARE THE SCHEDULES WITH RESPECT TO $$$$$ COST $$$$$

CONCLUSIONS • TWO STOREY CAR PARK

• AS/NZS 1170, NZS 3101, NZS 3404

• CONCRETE IS ONE OF THE MOST POPULAR MATERIALS FOR BUILDINGS BECAUSE IT HAS

• HIGH COMPRESSIVE STRENGTH, FLEXIBILITY IN ITS FORM AND IT IS WIDELY AVAILABLE.

• FOR SAFETY CONCRETE STRUCTURAL BUILDING, A STRUCTURAL ENGINEER MUST UNDERSTAND OF THE LOADING/ACTIONS, STRUCTURE ANALYSIS AND STRUCTURAL DESIGN.
