Abstract

The construction of high-rise buildings nowadays must be designed to be economical, have a symmetrical and good structure, and must be designed to be earthquake-resistant. Steel structure is one of the earthquake-resistant constructions that are better than concrete structure, since steel structure has a high ductility property. Ductility is the ability of the structure to deform in receiving compressive and tensile forces before the building collapses. EBF can be an alternative in earthquake-resistant buildings since the structure is a combination of two conventional portal systems, where the EBF system has a high level of ductility similar to Moment Resisting Frame (MRF) and also has a high elastic stiffness similar to Concentrically Braced Frames (CBF). The advantage of this system is that it has good structural ductility by designing the shear failure to occur in the link element, while the beam, column, and bracing elements remain in an elastic condition. The EBF Inverted V-type is a good configuration because the largest moment that creates a plastic hinge does not occur near the column, but rather at the ends of the link beam between two bracing joints. Therefore, this model structure is more advantageous because the plastic hinge that occurs does not cause the building to collapse. In addition to the structural system, the use of steel and composite concrete materials in building structures can be a solution in earthquake-resistant building planning. Composite structures are stronger and stiffer than non-composite structures, improving structural performance, allowing for faster construction time, and reducing material costs. Considering the background above, in this study, a modification was carried out on the Field Research Center UGM building which originally used Reinforced Concrete Frame Structure (RCFS) consisting of 3 floors, by modifying it with a composite steel-concrete structure with an EBF system and increasing the number of floors to 25. The EBF configuration used is Inverted V-Braced. This planning refers to and fulfills the structural safety requirements based on SNI 1729–2019, AISC 341–10, SNI 1727–2020, SNI 1727–2013 and SNI 2847–2019, SNI 1729–2020. From the planning results, the floor plate thickness is 11 cm and 12 cm using a material quality of f'c 30 MPa. The main beam dimensions use WF 700x300x15x28. The column dimensions use CFT (Concrete Filled Tube) 800x800x25, CFT 650x650x25, and CFT 600x600x25. The structure is braced using EBF with a link length of 150 cm (Short Link) and bracing dimensions of WF 400x400x20x35. The beam dimensions use 400x600 mm. The foundation uses spun piles D60 with a depth of 8 m.
