Abstract

Earthquakes have the potential to cause significant damage to multi-story buildings; therefore, structural systems that can improve seismic performance are required. This study aims to compare the structural response of a 10-story office building in Surabaya using fixed base, shear wall, and base isolation systems with High Damping Rubber Bearing (HDRB). The analysis was conducted using ETABS software in accordance with SNI 1726:2019, considering parameters such as inter-story drift, base shear, structural period, and P-Delta effects. The results indicate that the shear wall system provides the highest stiffness, while the HDRB system significantly increases the structural period and reduces inter-story drift in the upper structure. Although it results in larger deformation at the base, the HDRB system still meets the performance criteria and is recommended for buildings in seismic-prone areas.

Abstract

Indonesia is a region with high seismic activity, including Surabaya, which is influenced by the Kendeng Fault. This study aims to analyze the effect of using High Damping Rubber Bearing (HDRB) on the seismic performance of a six-story office building. The analysis was carried out using ETABS based on SNI 1726:2019 by comparing a fixed-base structure and an HDRB-isolated structure. The parameters evaluated include natural period, base shear, interstory drift, and P-Delta effects. The results show that HDRB increases the natural period and significantly reduces base shear and interstory drift. Therefore, HDRB is effective in improving seismic performance and can be considered as an alternative design for buildings in moderate seismic hazard areas.

Abstract

Geopolymer is an environmentally friendly concrete based on pozzolanic materials rich in silica and alumina. The compound reacts with an alkali activator thru a polymerization process, resulting in binding properties. Geopolymer concrete generally requires an activation temperature of around 60℃ to enhance compressive strength, making it less practical for large-scale applications. Therefore, this study examines the most optimal room temperature curing method for the compressive strength of fly ash-based geopolymer mortar. The research uses 12M  and an activator ratio of :  of 1:1. The test specimens in the shape of cubes were cured using three methods: water curing, moist curing, and wrap curing. The compressive strength test was conducted at 7 and 28 days of age. The results show that at 7 days of age, water curing produced the highest compressive strength of 22.24 MPa. However, at 28 days of age, wrap curing produced the highest compressive strength of 47.09 MPa. This shows that wrap curing is capable of maintaining internal moisture and preventing water loss due to evaporation, thereby making the geopolymerization process more stable and forming a denser structure. Thus, wrap curing becomes the most optimal curing method because geopolymer does not require water as the main reaction component.Geopolymer is an environmentally friendly concrete based on pozzolanic materials rich in silica and alumina.
