“…Namun pengalaman adaptasi fenomena gempa dan implikasi di bidang infrastruktur tertama bangunan gedung di beberapa negara bukanlah hal yang mudah dan cepat diterapkan (lihat Mushkatel and Weschler, 1985;Irtem et al 2007;Gurenko et al, 2006;Cetin, 2013). Peran pemerintah haruslah dominan karena pada hakekatnya dampak sosial selalu terbentur pada kultur dan kebiasaan yang terbatas, kompleks dan kadang tidak karuan dan terfragmentasi (Rhodes, 2011).…”

“…Idealnya, suatu struktur bangunan rumah sakit pasca gempa diharapkan mampu untuk tetap berdiri dan secara fungsional masih bisa memberikan pelayanan kesehatan (Achour et al, 2011). Beberapa pengalaman untuk mengurangi dampak gempa pada bangunan rumah sakit umum telah dilakukan di berapa negara seperti di Banglades, Turki dan Chili (Sharif et al, 2011;Irtem et al, 2007). Teknologi bangunan tahan gempa pada rumah sakit telah mulai berkembang pasca gempa Meksiko tahun 1985, terutama di negara-negara maju seperti di Jepang dan Amerika Serikat.…”

“…Pengalaman di Turki mengidentifikasi beberapa penyebab keruntuhan gedung akibat gempa antara lain berkaitan dengan faktor-faktor seperti tidak adanya pembaruan peta risiko gempa, adanya modifikasi konstruksi selama periode penggunaan bangunan, permasalahan tidak akuratnya administrasi proyek dan desain sehingga sulit dilakukan mitigasi penyebab kerusakan struktur, kegagalan retrofit dari gempa sebelumnya, serta kurangnya perhatian pada masalah pemeliharaan gedung yang menyebabkan reduksi kapasitas atau kekuatan bahan (Irtem et al 2007). Yang menarik dari kebijakan pemerintah Turki pasca beberapa gempa hebat adalah upaya pemberian insentif dan regulasi fiskal bagai peraturan bangunan gedung.…”

“…Single degree-of-freedom (SDOF) system approach is used in determination of demands in NSPs recommended in ATC 40 and FEMA 356, which is called as capacity spectrum method (CSM) and displacement coefficient method (DCM), respectively. However, these procedures have some discrepancy in determination of displacement demand for the same building model and under a specific ground motion [8] [9]. Consequently, same building performances may not be obtained due to these discrepancies in the analysis procedures.…”

“…Chopra and Goel [14] found some flows in CSM version of ATC 40. The ATC 55 project derives the optimal vibration period and damping ratio parameters for the equivalent linear system by minimizing the differences between its response and that of the actual inelastic system and rectifies the flows in the original version [8]. For this reason, it is of prime importance to investigate effects of the CSM versions in performance evaluations of RC buildings, having different structural characteristics, within PBD and assessment concept.…”

The aim of this study is to assess the performance objectives defined in the Iraqi Seismic Code (ISC) in order to make a realistic evaluation related to Performance-Based Seismic Design (PBSD) of multi-story reinforced concrete buildings and also to compare and evaluate structural response demands obtained from nonlinear static analysis procedures according to two versions of the capacity spectrum method (CSM) which are recommended in ATC 40 and ATC 55. Two groups of three-dimensional RC buildings with different heights, designed according to Iraqi Building Code Requirements for Reinforced Concrete (IBC), are investigated. Pushover analyses are carried out to determine the nonlinear behavior of the buildings under three different seismic hazard levels, for two Iraqi seismic zones, of earthquake loads. In order to determine performance levels of the buildings, maximum inter-story drift demands and plasticizing sequence are determined and compared with the related limits using the CSM recommended in ATC 40 and ATC 55. From the results of this research, it can be concluded that RC buildings designed according to the Iraqi codes sufficiently provide the performance objectives stipulated in the ISC. Comparing structural response quantities obtained from the two versions of CSM, effects on performance evaluations of the buildings are investigated comparatively, as well.

SUMMARY Steel space framed hall buildings are dedicated as shelters for people suffering from earthquakes. In general construction, steel space frames are built on reinforced concrete (R/C) frames or wall structures above the bottom side. For this reason, the bottom side has higher rigidity comparing with the upper side. In Turkey, where there is a very high earthquake risk, earthquake‐resistant steel space framed structures is an important issue. In this current research, hall buildings in Turkey, involving two different rigidity parts as R/C and steel, are taken into consideration regarding earthquake effect. In this study, three different hall structures were modeled with different elastic moduli for the analysis part. Nonlinear time history analyses were applied with 25 different earthquake data for performance estimation. After the time history analyses, probabilistic seismic assessment was carried out for the model buildings through fragility analyses. For each model, analysis results were evaluated and compared. As a result, the hall buildings were found to be vulnerable to damage during expected future earthquakes. Moreover, elastic moduli have significant effect on the structural response.
