Abstract

Abstract: Behavior analysis and performance evaluation of frame structures with infilled wall (RDP) has been done by making four structure models, a model of open framework (MOF) and three RDP models (M1, M2, and M3). In the RDP models, walls in transverse direction of the building was placed fully on the floor 2, 3 and 4, and varied on the ground floor. The wall in longitudinal direction, however, was not included in the model because of the holes and irregularity. The walls on the ground floor were placed fully for M1, at the ends and middle of the building for M2, and none for M3. The walls were modeled as 3 diagonal struts that can withstand compressive stress only. The behavior of the structure was observed through linear elastic analysis by comparing story drift and its ratios, while the performance of the structure was evaluated through nonlinear static Pushover analysis using SAP2000. The analysis showed that the inclusion of infill walls in the model increases the stiffness of the structure. The values of drift at roof level were 8 mm, 10 mm, 12 mm and 28 mm for M1, M2, M3, and MOF, respectively. Soft story mechanism was detected in the RDP models with irregular wall placement with maximum drift ratio of 157% and 249% for M2 and M3, respectively, while MOF and M1 with continuous wall have drift ratios of 101% and 92%. Discontinuous walls also decrease performance of the structure. Pushover analysis results in the transverse direction showed that M1 is capable of resisting the largest base shear force 658 tons with a level of performance Operational (O), while M2 with O performance levels capable of resisting base shear of 437 tons. M3 and MOF can resist the lowest base shear force of 270 tons and 279 tons with performance level of Immediate Occupancy (IO) and Life Safety (LS). Pushover analysis in the longitudinal direction of the building (where the wall was not modeled) showed that, MOF can resist the least base shear compared to the three RDP models. This suggests that the struts on the transverse direction also affect the stiffness of the structure in the longitudinal direction. The actual value of ductility in the transverse direction of the structure are 4.6; 2.9; 2.8; 3.4; for MOF, M1, M2 and M3, respectively. While in the longitudinal direction the ductility are 3.2; 3.6; 3.8; 3,9. All models ductility values are smaller than the design value, i.e., ยต = 5.

Abstract

Analisis kinerja struktur merupakan metode analisis struktur pasca elastis yang mana bertujuan untuk mendapatkan besarnya gaya geser dasar dan perpindahan maksimum pada struktur bangunan. Pada paper ini ditampilkan hasil evaluasi kinerja struktur gedung yang telah dibangun dengan sistem rangka terbuka yang berfungsi sebagai rumah susun empat tingkat yang didesain berlokasi di Malang, Jawa Timur. Gedung ini didesain dengan beban gempa berdasarkan respon spektrum dari peta gempa Indonesia. Metode analisis kinerja struktur dilakukan berdasarkan metode Spektrum Kapasitas (ATC-40) dan metode Target Perpindahan Modifikasi (FEMA 440). Hasil analisis kinerja baik berdasarkan pendekatan Spektrum Kapasitas maupun Target Perpindahan Modifikasi menunjukkan tingkat atau level kinerja yang sama yaitu Immediate Occupancy (IO). Namun kondisi eksisting struktur pada performance point atau level kinerjanya terdapat beberapa elemen strutkur mengalami sendi plastis Collapse (C). Hal ini menunjukkan kinerja struktur belum memenuhi kriteria ATC-40 dan FEMA 440. Sehingga perlu dilakukan perbaikan terhadap elemen strutkur yang mengalami collapse (C) untuk mendapatkan level kinerja sesuai dengan metode ATC-40 dan FEMA 440.
