Abstract

The selection of material is one of the important aspects used to design a building as it is known that every type of material has a different characteristic. The steel material used as the main component of building structure because of its ductility is more than another material which is the main criterion to design an earthquake resistance building. In this paper, an earthquake steel resistant structure building will be design. This building structure will consist of a five-story office with a regular structure configuration. A special moment frame (SMF) used as the resisting structure system of the earthquake loads as the amount of its load is analyzed using the spectrum response method. The steel material used is type of A36 (fy = 250 MPa; fu = 400 MPa), concrete used f’c = 30 MPa. The design process then produces an earthquake steel resistant structure building, which satisfies the requirement of story drift with a maximum number of story drift occurred in the 2nd story which is 93.5 mm less than allowed story drift that is 95 mm. A structure element dimension used is a beam with a profile of W16x7x40 for every level in the X-axis direction, and the beam with a profile is W14x6.75x38 for every level in Y-axis direction, 12 cm thick plates and column with a profile W14x16x211 is regularly used to every level.

Abstract

Buildings damages due to earthquakes generally happen because designs of the buildings do not consider earthquake resistance aspects and do not fulfil the technical standards of earthquake resistant buildings. The structure designed in this work was a seven-storey office building, with a symmetrical design plan. The earthquake-resisting system used was dual system with special moment resisting frame (SMRF) and special shear wall for reinforced concrete. The materials used in this design were concrete with compressive strength of f 'c = 30 MPa, Plain Steel Bars Grade 24 (fy = 235 MPa), and Deformed Steel Bars Grade 40 (fy = 390 MPa). The calculation structural elements results gave: the size of main beams of 40 x 60 cm2, with reinforcement varying from 4D22 to 12D22 in the support area and from 3D22 to 5D22 in the midspan area; secondary beams with the size of 25 x 40 cm2, with reinforcement of 2D22 both in the support area and midspan area; the size of columns were 95 x 95 cm2, with reinforcement varying from 20D25 to 28D25; a 30 cm thick of shear walls reinforced with 2D22-175 mm (in x-axis) and 2D22-125 mm (in y-axis); 12 cm thick slabs reinforced with Ø12-200 mm . For the tie beams with the size of 40 x 55 cm2, had reinforcement varying from 2D22 to 4D22 in the support area and from 3D22 to 5D22 in the midspan area. Pushover analysis results in a maximum total drift  of 0,00425 which means the performance level of the structure is Immediate Occupancy
