Abstract

Sukawati Market Building has 4 floors and 1 basement with a total building area of 1136.16 m2. It was designed to use a flat slab structure system with the addition of drop panels that maintained the height or story clearance while reducing total building height by eliminating the interior beams. The structure was designed follow the Indonesian Standard for reinforced concrete building design guideline and assessed through finite element simulation. The shear capacity of the flat slab was determined by the strength of the concrete and its dimensions. The reinforcing bar of flat slabs with drop panels is determined in the same way as the reinforcing bar of concrete slabs. Based on the results, the design efficiently resists the forces demand while meeting the deflection requirement, reflecting the structure system's safety and serviceability. The structure system also maintains the total height of the building in order to comply with local high-limit regulation.

Abstract

Indonesia has the latest seismic standard, namely SNI 03-1726-2012 which replaces the previous seismic standard, namely SNI 03-1726-2012. This study aims to compare the calculation and analysis of the result of the Transit-Oriented Development (TOD) apartment in Pondok Cina, Depok based on SNI 03-1726-2012 and SNI 03-1726-2019 and find out what parameters make a significant difference between SNI 03-1726-2012 and SNI 03-1726-2012. SNI 03-1726-2019. From the comparison results, there was an increase in the parameter values ​​of SS and S1 in SNI 03-1726-2019, resulting in the influence of the parameter values ​​of SDS and SD1 which became the reference for calculating the acceleration value of the response spectra in SNI 03-1726-2019. The value of the basic static shear force in the X and Y directions in SNI 03-1726-2019 increased by 18% from the value of the basic static shear force in SNI 03-1726-2012 and the value of the dynamic basic shear force in the X and Y directions in SNI 03-1726- 2019 experienced an increase of 15% from the value of the dynamic base shear force in SNI 03-1726-2012. The basic shear force increases because the acceleration spectral design response has a high increase in 03-1726-2019 compared to SNI 03-1726-2012. Based on the control of the performance level of the Transit-Oriented Development (TOD) apartment building, Pondok Cina Depok, is included in the Immediate Occupancy, meaning that when an earthquake occurs, the building does not suffer heavy damage, can still be used and the risk of casualties is very small. Performance-based planning can provide information on how the building behaves during an earthquake and the extent to which the earthquake will affect the structure.

Abstract

Low-rise and mid-rise structures often possess natural periods that coincide with high-energy seismic response plateaus, rendering them susceptible to significant response amplification. This study evaluates the comparative effectiveness of High Damping Rubber Bearings (HDRB) in mitigating these risks for 4-story and 8-story office buildings under Indonesian seismic conditions. Using rigorous Non-Linear Time History Analysis (NLTHA) in the dominant X-direction, the research examines period elongation, lateral displacement, inter-story drift, peak floor acceleration, and base shear attenuation. Scientific findings reveal that HDRB transitions structural behavior into a near-rigid-body motion, reducing normalized inter-story drift to 0.26 and 0.12, and base shear by up to 71%. Furthermore, peak floor acceleration is curtailed by 51% to 59%, ensuring the protection of sensitive non-structural components. The results demonstrate that while base isolation provides superior seismic protection for both building scales, its efficacy in intercepting seismic energy and preventing operational disruptions is significantly more pronounced in mid-rise structures. This study confirms that HDRB is an increasingly vital strategy for enhancing functional resilience as building height increase.
