ABSTRACT <br /> <br /> <br /> <br /> <br /> EARTHQUAKE RESISTANT STEEL STRUCTURE DESIGN USING SPECIAL CONCENTRICALLY BRACED FRAME TYPE INVERTED V SYSTEM WITH VERTICAL IRREGULARITY <br /> <br /> <br /> <br /> <br /> By <br /> <br /> <br /> <br /> <br /> Bobby Arlan <br /> <br /> <br /> <br /> <br /> NIM : 15010097 <br /> <br /> <br /> <br /> <br /> (Faculty of Civil and Environmental Engineering) <br /> <br /> <br /> <br /> <br /> Special Concentrically Braced Frame is one of the earthquake resistant steel structure that is commonly used. This structure system has many benefits such as the high stiffness nominal. In this final project, 12 story steel structure building is designed using Special Concentrically Braced Frame type inverted-V system. The design refers to AISC 360-10 and AISC 341-10. The seismic load is calculated based on SNI 1726-2012. The type of vertical irregularity that is analyzed in the building is the soft story. Capacity design and performance based design concept are used to design the building. The design process is carried out for two buildings with different number of earthquake resistant portals, which is three bays and four bays. Comparison of the buildings is carried to see the effective number of portals needed to design the building. The comparison is also performed to another structure system, which is the Eccentrically Braced Frame. <br /> <br /> <br /> <br /> <br /> In this final project, the comparison shows that the 4-Bays SCBF is better that the 3-Bays SCBF. The 4-Bays structure shows a higher stiffness level than the 3-Bays structure. It is concluded that the increasing of the bays contributes to the increasing of the structure stiffness. But the 4-bays structure has lower ductility level and higher weight of the structure. From the comparison of the structure system, it is concluded that Eccentrically Braced Frame system is better than Special Concentrically Braced Frame for the design of 12 story building because of the smaller total weight of the structure and the higher ductility level.
