INTRODUCTION

Overview Earthquake Situation in Indonesia

Location of Indonesia which is the confluence of three plates the Indo-Australian plate, Pacific plate and the Eurasian plate

INTRODUCTION

Types of building structure in Indonesia

Concrete building structure • Building with the concrete structure

usuallly for house and high building

• Concrete is able to withstand the compression force and anti corrosion

• The construction of concrete structure is low

• The concrete can be modified easily in construction

Bismillah

Types of building structure in Indonesia

Steel building structure

• Building with the steel structure usually for the storage building or the high rise building which is good for high earthquake zone

• The construction of the steel structure is fast because it has uniform structure

• The ductility of the steel can avoid the building from collapse suddenly cause of the earthquake

• Cost construction is expensive

Design framework

• Project Objective. Design the steel storage building 2 floors, which the length is 60 m, the width is 22 m and the height is 9,5 m by considering the earthquake zone 2 but I change into the earthquake zone 6 in Jakarta, the Capital city of Indonesia. • Main Research Question How are the design and the calculation of the steel storage building construction in Jakarta Indonesia, which is considering earthquake zone 6?

General information

General information of the steel storage building

Location : Jakarta, Indonesia Storey : First floor covered (h=5,5 m) Second floor covered (h=4 m) Wall in first floor : Brick Wall in the second floor : Brick Regulation for calculation : SNI 03-1726-2002 for steel building SNI 03-1729-2002 for Earthquake

Bismillah

General information

• Jakarta is located in earthquake zone 2, for the modification I change into the earthquake zone 6

• The earthquake can reach 8,6 SR in Jakarta

Load Calculation

Portal Load P1 = 14529,5 kg P2 = 16010 kg P3 = 16160,5 kg P4 = 8000 kg P5 = 16080,8 kg

Roof load: Dead load = 161,22 kg Live load = 169,62 kg

Earthquake Load Calculation

T = 0,085´ H3/4

= 0,085´9,53/4

= 0,478 second

T : Time for the natural vibration that determines the magnitude of the earthquake response factor for structure of the building

H : Total height of the building V : Shear load Ct : The seismic response factor ( for earthquake zone 6,Ct is 0,9) I : Main safety factor ( for the earthquake zone 6, I is 1) Wt : Total weight of the building R : Reduction earthquake factor ( for the earthquake zone 6, R is 8,5 ) Fi : Earthquake load for the structure of the building Zi : Height of each floor start from first floor

Connection A Roof Connection

• Φbolt = 10 mm • 2 bolts for each beam • For beam: 60x60x10

Connection B

Lattice Beam Connection

• Φbolt = 10 mm • 2 bolts for each beam • For beam: 60x60x10

Connection C

• Φbolt = 10 mm • For roof beam I used 8

bolts • For botttom beam I used 7

bolts • For beam : 60x60x10

Connection D

• Φbolt = 16 mm • Angle profile for the connection is 200x200x16 • Angle profile in the middle for the connection is 150x150x14

Connection between Beam and Column

Connection E • Φbolt = 22 mm

• Angle profile for the connection is 200x200x16

• Angle profile in the middle for the connection is 150x150x14

Beam and Column connection

Conclusion

The steel storage building with two floors can be built in Jakarta which is located in earthquake zone 6 by using : Column which is used WF 400x400x15x15 Beam which is used WF 350x250x9x14 Joist which is used WF 350x175x7x11 The structure which mention above are the main structure that I used in the steel storage building design
