Infrastructure plays an important role in human activities, such as in government sector, education, economics and social sector. In addition, Indonesia is one of the countries which located in the ring of fire. As a result, Indonesia is one of the countries susceptive to earthquakes which is one of the main causes of a collapsing structure. Therefore, in order to maintain the economic growth sustainably, the criteria for earthquake-resistant building design must be at least achieve a life safety performance so that the building is allowed to damage severly but still prevented to collapse. This final project discusses about the design of earthquake-resistant structures and basement on projects located in Medan, North Sumatra. This building has 3 parts, namely a podium with 4 floors which functions as a mall, 2 towers which function as offices with a height of 32 and 36 floors respectively, and 3 basement floors which function as parking lots. This project location has a soft soil conditions with high earthquake acceleration and categorized in the Seismic Design Category D. Therefore, the upper structure of this building is designed using a dual structure system consisting of a Special Moment Resisting Frame System (SMRF) and Special Structural Wall System. While for the basement, it will be designed using the Intermediate Moment Resisting Frame System (IMRF) and Special Structural Wall System. In this final project, upper-structure and basement models will be carried out separately using ETABS 2017 perangkat lunak, so that the structural elements will be designed using force result from the perangkat lunak. In addition, a two-stage analysis is carried out in this design process where it is assumed that the upper structure is restraint on the ground floor but have to meet the requirements stated in SNI 1726: 2012 so that the assumption may be used. In addition, the earthquake design uses static equivalents and the response spectrum refers to SNI 1726: 2012. The design of reinforced concrete structural elements will refer to SNI 2847: 2013.
