Abstract

When planning a tall building structure, the deviation due to lateral forces is very important to be taken into account in the planning of tall building structures. To reduce the amount of deviation in the structure adding by special structural elements, as shear walls. With the shear wall, can increase the stiffness of the building structure and absorb large shear forces along with higher the building structure and lateral force on structure will not fully accepted by frame structure which will result a decrease in deviation. Guestwing 1 The Ritz Carlton Hottel located in South Kuta District, Badung Regency, Bali. This building has a height of 20.2 m consisting of 6 floors. Planning with 2 models: a) SRPMK Existing Modeling, b) Dual System Model. Material specifications and loading are the same, just different in addition of shear walls and reducing the dimensions the building. Based on the results the analysis of the two models, the largest inter-storey deviation value in the existing model X=52.014mm; Y=47.960mm and for the dual system model X=25.614mm; Y=26.026mm. From the results of deviation analysis on both models, can be concluded that with addition of shear walls, there is a decrease in deviation 63.27% in X direction and 68.18% in Y direction. The most significant decrease occurs in dimensions and reinforcement of column K1 from size 350x800mm with 22 D22 reinforcement to column 300x600mm with 18 D22 reinforcement, beam B3 250x450mm for support area 17 D13 and field area 10 D13 to beam 250x400mm with the number of support reinforcement 11 D13, and the number of field reinforcement 7 D13. From the results of this planning can be used as a consideration for the construction of the next building for the use of shear walls in the structure.

Abstract

Development in Indonesia is currently experiencing very rapid development, with the development of technology in the construction sector, to meet the aesthetic aspects of buildings and due to limited land, it is planned that building construction will be multi-storey. In the planning and design of multi-storey buildings, the decision to include or not include a basement has significant implications for the structural behavior of the building, particularly in relation to lateral drift and overall stability. Lateral drift, or horizontal shift between levels, is a crucial parameter in ensuring the comfort and structural integrity of buildings when facing lateral loads such as earthquakes. Comparative analysis between these two models is important to understand the influence of the presence of a basement on the dynamic response of a building. The main focus is to evaluate the extent to which the presence of a basement influences the lateral stiffness and dynamic response of the building. Analysis shows that the drift value produced by the model without basement is smaller than the model with basement. Namely, the maximum value for the model without a basement is 17.3 mm and the model with a basement has a maximum value of 29.1 mm with a clearance of 54.6 mm on the 3rd floor in the x direction and in the Y direction. The maximum value for the model without a basement is 25.4 mm and the model with a basement has a maximum value of 43.6 mm with a clearance of 54.6 on the 3rd floor. Based on the results of the analysis that has been carried out, it shows that both models have met the earthquake resistance requirements such as base force. seismic, permissible deviations between floors, capital, and mass inclusions.

Abstract

This study was conducted to analyze the performance of multi-story building structures using a flat slab system with drop panels, both in single and adjacent configurations. The research was motivated by Indonesia’s high seismic activity and the growing need for efficient and easily constructed structural systems that also provide aesthetic benefits. The main objective was to evaluate and compare the lateral displacement behavior of both structural models and assess their compliance with the drift limits specified in SNI 1726:2019. The analysis was performed through numerical modeling using ETABS software, with load combinations following SNI 1727:2020 for minimum design loads and SNI 2847:2019 for reinforced concrete strength provisions. The structural models consisted of a 200 mm thick flat slab and a 300 mm thick drop panel, supported by beams and columns designed to meet flexural and shear capacity requirements. The analysis results indicated that the maximum displacement was 34.584 mm in the X direction and 12.832 mm in the Y direction, both within the allowable drift limits. The adjacent building model exhibited average lateral displacements 1.25 times smaller in the X direction and 3.75 times smaller in the Y direction compared to the single structure, indicating a stiffness improvement due to inter-building interaction. All structural components, including the 7.6-meter-deep pile foundation, satisfied the strength and stability criteria. It was concluded that the flat slab system with drop panels is structurally efficient and seismically safe, providing a reliable alternative for building design in earthquake-prone regions.
