Abstract

To meet the community's educational needs, existing schools are encouraged to increase their student capacity by building new facilities. As public infrastructure, school buildings need to be designed as reliably as possible, including their earthquake resistance. To ensure that a building is earthquake-resistant, this study analyzes it using the ETABS software. This research was conducted in Semarang City on a four-story school building. The results indicate that the Participating Mass Ratio of the school building is greater than 90%. The comparison of the Response Spectrum with the Equivalent Static method shows 92.80% along the X-axis and 87.85% along the Y-axis. Based on the calculated inter-story drift, if an earthquake occurs with the provided data, the building is expected to withstand the event without collapsing.

Abstract

The research was conducted in the Kudus Regency Public Services building which originally had a floor area of 1172 m2. In 2022 there will be development, so a new floor will need to be added. Where the land area cannot be used to build horizontally, add vertical floors to a 2-story building to become 3 floors. The research was carried out by testing the quality of concrete using the Hammer Test, obtaining a result of 20.75 MPa, then modeling analysis was carried out using SAP 2000 v14 software and manual calculations based on SNI 03-2847-2002, SNI 031726-2012, and SNI 1729-2015. This analysis was carried out in 3 stages, the first was an analysis of the initial conditions of the existing building, the second was an analysis of the existing structure with the additional load of the new floor, and the third analysis was with the additional load and structural strengthening. The results of the structural analysis stages 1 and 2 stated that the beam structural elements experienced overstrength (O/S) or could not withstand the additional load of the 3rd floor. With this data, structural reinforcement calculations were carried out using the concrete jacketing method with a number of longitudinal reinforcement 7D16 stirrups Ø10-100 for beams and the amount of longitudinal reinforcement 8D19 stirrups Ø10-100 and the method of strengthening with steel profile IWF 200.200.8.12.
