Abstract

In the construction, it must be able to be used according to its function so that it can be used for a long time. The concept of construction that has sufficient strength and allows for large spaces without affecting aesthetics has emerged in recent decades. A flat slab is one of the advances in the construction system of a two-way concrete plate that distributes the working load directly to the column element without using a beam. The use of drop panels can increase the strength of the plate by resisting the sliding style of the pons and reducing the negative moment reaction that occurs on the plate and column. In the analysis, the results used a flat slab with a thickness of 200 mm, with bones in the x and y directions at the focus of As D16-100 mm and As’ D16-200 mm, whereas in the columns of column directions x and y, the field part is mounted with As D13-100 mm and As‘ D13-200 mm. In the middle column of directions X and Y, use the bones of As D13-100 mm and As‘ D13200 mm. Used a drop panel of 300 mm. For the lift area, an L type column with dimensions of 450 mm x 450 mm is used. The bars used are TB1, TB2, B1, and RB, and the columns used are 500 mm x 500 mm and 400 mm x 400 mm. The planned foundation uses a cylinder-shaped pillar with a depth of up to 8 meters.

Abstract

This study examines the planning of high-rise building structures in Indonesia, focusing on the application of Special Moment Resisting Frame (SMRF) systems under seismic conditions. Situated within the Pacific Ring of Fire, Indonesia frequently experiences significant earthquakes due to the convergence of three continental plates. Previous research indicates that the design of high-rise buildings necessitates careful attention to dimensions and reinforcement to ensure structural strength and stability. The SMRF planning method, which applies the principle of strong column weak beam, has been analyzed across various case studies, including designs for office buildings, hotels, laboratories, and educational facilities.Furthermore, this study compares the structural performance using different concrete strengths, specifically 41.5 Mpa and 24.9 Mpa, in the construction of prison walling at the Kejati Detention Center. Through quantitative analysis and structural modeling using ETABS V.20 software, this research identifies differences in base shear and inter-story drift between the two concrete strengths. The findings provide insights into the effectiveness of higher-grade concrete usage and its potential impacts on the strength and structural quality of buildings. The implications of this research can guide practitioners in selecting the appropriate construction materials to enhance performance and cost-efficiency in high-rise building projects in Indonesia.
