Evaluasi Kinerja Struktur Gedung Bertingkat Menggunakan Pendekatan Desain Berbasis Kinerja

In Indonesia, earthquake-resistant structures are governed by SNI as design codes, which are updated on a regular basis. As a result, existing buildings with outdated requirements must be reviewed so that the building's performance may be assessed in light of the most recent codes. Pushover analysis and direct displacement-based design are used to characterize the real condition of the building in order to assess its performance. The 7-story reinforced concrete building structure in this study was designed according to SNI 03-2847-2002 and SNI-1726-2002. This structure will be evaluated utilizing the FEMA 440 and FEMA 356 procedures, as well as SNI 1726:2019. The results show that the structure meets the minimal performance limit criteria (which is life safety) in terms of displacement and drift values from the pushover analysis, based on FEMA 356 and FEMA 440 performance levels. The evaluation indicates better structural response parameter values (R, Ω0, and Cd) than that of SNI 1726:2019, indicating that the building performance is good and capable of withstanding the design earthquake load.

Karakteristik Mortar Polimer Epoxy Resin Dengan Fiberglass

Nowadays, the developments of technology in construction are progressing very rapidly, one of which is mortar without using cement material. This encourages the development of concrete and mortar technology so that it can be widely used to repair structural or non-structural damages. In these conditions, a binder is needed in the form of an epoxy resin polymer with added fiberglass to get a strong material result in a short time. A mixture of 75% sand and 25% epoxy resin from the volume of the test object resulted a mortar compressive strength of 35.50 MPa with a specific gravity of 1.505 kg/m3. The results showed that the variation of the compressive strength of the epoxy resin mortar without fiber was higher than the variation with fiberglass. This was due to the addition of fiberglass reducing the composition of the percentage of epoxy resin which results in reduced bonding power in the mixture. The flexural strength of a mortar with variations using fiberglass was 8 MPa and showed the best performance, although the difference was not too far from the variation without fiberglass. This was because the addition of fiberglass can reduce cracks, so that the fibers can bind well. The tests had been carried out including tests of the compressive strength, flexural strength, and Scanning Electron Microscope (SEM).
