Abstract
Perkembangan konstruksi di Indonesia juga menghadapi berbagai tantangan terutama dikarenakan kondisi geografis. Salah satu jenis bangunan di Indonesia yang diragukan kekokohannya disebut bangunan irregular. Bangunan irregular lebih kompleks untuk dirancang dan dibangun dikarenakan perilaku dinamisnya yang lebih sulit diprediksi terutama dalam kondisi gempa bumi. Salah satu solusi yang dapat dilaksanakan adalah dengan mengaplikasikan konstruksi perkuatan seperti pengaku (bracing). Bangunan ini dianalisa menggunakan Metode Performance Based Design (PBD) dan Pushover Analysis untuk mengetahui respon struktur terhadap beban gempanya. Penggunaan kedua metode ini sudah dianggap mendekati dengan kondisi realitas struktur pada saat terkena beban gempa. Pushover Analysis akan membantu untuk mendapatkan Performance Level, Performance Point, Drift, dan Displacement dari struktur yang akan dibandingkan sebelum dan sesudah diaplikasikan pengaku (bracing) baja pada bangunan irregular. Tiga jenis konfigurasi penempatan pengaku (bracing) baja digunakan sebagai perkuatan pada arah X-X dan Y-Y. Hasil analisis menunjukkan bahwa ketiganya berkontribusi dalam mengurangi displacement dan drift dibandingkan dengan struktur tanpa perkuatan. Ketiga tipe ini termasuk dalam klasifikasi Performance Level Immediate Occupancy yang menandakan bahwa struktur tetap dapat digunakan setelah terjadi beban gempa. Selain itu, semua tipe tersebut memenuhi standar keamanan karena simpangan pada setiap level masih berada dalam batas izin sesuai dengan SNI 1726:2019.
English Abstract
The development of construction in Indonesia also faces various challenges mainly due to geographical conditions. One type of building in Indonesia that is of questionable sturdiness is called irregular buildings. Irregular buildings are more complex to design and construct due to their dynamic behavior which is more difficult to predict especially in earthquake conditions. One solution that can be implemented is to apply reinforcement construction such as bracing. This building was analyzed using the Performance Based Design (PBD) and Pushover Analysis methods to determine the structural response to the earthquake load. The use of these two methods is considered to be close to the real conditions of the structure when exposed to earthquake loads. Pushover Analysis will help to obtain the Performance Level, Performance Point, Drift, and Displacement of the structure which will be compared before and after the application of steel bracing in irregular buildings. Three types of steel bracing placement configurations were used as reinforcement in the X-X and Y-Y directions. The analysis results show that all three contribute to reducing displacement and drift compared to the unreinforced structure. All three types are classified as Performance Level Immediate Occupancy, which indicates that the structure can still be used after an earthquake load. In addition, all types meet safety standards because the deviation at each level is still within the permit limit in accordance with SNI 1726:2019.
