Collapse Behavior

Pushover analysis is a non-linear static analysis to determine the collapse behavior of a building or structure. The analysis is carried out by giving a static lateral load pattern to the structure, which is then gradually increased by a multiplier until a buliding movement target is reached. This final assignment research was conducted to determine the performance point based on ATC-40, to determine the performance level based on ATC-40, and to determine the performance level based on FEMA 356. The research method used the response spectrum with the SAP2000 v14 program. The result of the performance point in building with the values of Sa = 0,737, and Sd = 0,200 for the push X, while the values of push Y Sa = 0,680, and Sd = 0,225. The calculation of ATC-40 in building shows the value of the drift ratio in the X direction 0,01165 and the drift ratio Y direction 0,0127 at the level of performance Immediate Occupancy (IO). The result of FEMA 356 calculation in building shows the value of the lateral displacement target structure of the X direction structure = 0,00437 (0,437 %), and the value of the lateral displacement target of the Y direction structure = 0,006 (0,6 %) and at the level of performance Immediate Occupancy (IO). Then it could be concluded that The Dental & Mouth Hospital of UGM Prof. Soedomo, was at the level of performance Immediate Occupancy (IO), meaning that the building was still safe and could be reused after the earthquake and don’t occured serious demage.

ABSTRACTAlthough elastic analysis gives a good indication of the elastic capacity and behavior of a building, but the elastic method can’t predict when the first yield will occur, and the failure mechanism and account for redistribution of member forces when the plastic hinges progressively formed. The use of inelastic procedure for evaluation is an attempt made by engineer in the past days to better understand how the structure will behave when subjected to strong earthquake, assuming the elastic capacity of the structure will be exceeded. In this research the pushover analysis was done using the modelling criteria of FEMA 356. The modeling of C-flanged shear was done using line element with the equivalent strength and stiffness properties. Target displacement was calculated using the displacement coefficient method of FEMA 356. Based on the analysis the triangular load pattern resulted in larger target displacement than the uniform load. But the uniform load pattern gives larger seismic response than the triangular load pattern. The uniform load pattern resulted in Life Safety performance level, while the triangular load pattern resulted in Immediate Occupancy, based on the two load patterns used the structure resulted in Life Safety performance level.ABSTRAKWalaupun analisis elastik memberikan indikasi yang baik mengenai kapasitas dan perilaku elastik dari suatu gedung, tetapi metode elastik tidak dapat memperkirakan kapan pelelehan pertama terjadi, serta mekanisme kegagalan apa yang mungkin terjadi pada bangunan tersebut, dan memperkirakan redistribusi dari gaya- gaya dalam ketika pembentukan sendi plastis secara progresif terjadi. Fungsi dari analisis inelastik, sebagai prosedur untuk mengevaluasi bangunan, yang merupakan usaha dari insinyur-insinyur terdahulu memahami bagaimana struktur akan berperilaku apabila dikenai gempa kuat, dimana diasumsikan bahwa kapasitas elastik gedung telah terlampaui. Dalam penelitian ini dilakukan pushover analysis menggunakan kriteria pemodelan berdasarkan FEMA 356. Pemodelan dari dinding geser bersayap C dilakukan menggunakan line element dengan kekuatan dan kekakuan yang ekivalen. Target perpindahan dianalisis menggunakan metode coefficient of displacement dari FEMA 356. Berdasarkan analisis yang dilakukan didapat bahwa pembebanan segitiga lebih besar dibandingkan pembebanan merata. Namun, respons seismik yang didapat akibat beban merata, lebih besar dibandingkan beban segitiga. Pembebanan merata menghasilkan tingkatan kinerja Life Safety, sedangkan pembebanan segitiga menghasilkan tingkatan kinerja Immadiate Occupancy, berdasarkan kedua pembebanan tersebut didapat kinerja dari struktur tersebut adalah Life Safety.

Nowadays, as in the urban areas the space available for the construction of buildings is limited. So in limited space we have to construct such type of buildings which can be used for multiple purposes such as lobbies, car parking etc. To fulfill this demand, high rise buildings is the only option available. The performance of a high rise building during strong earthquake motion depends on the distribution of stiffness, strength and mass along both the vertical and horizontal directions. If there is discontinuity in stiffness, strength and mass between adjoining storeys of a building then such a building is known as irregular building. The present study focuses on the seismic performance of regular and vertical irregular building with and without masonary infills. In the present study G+11 building is considered for the analysis with modelling and analysis done on ETABS software v17.0.1. The earthquake forces are calculated as per IS 1893 (part 1): 2016 for seismic zone III. The width of strut is calculated by using equivalent diagonal strut method. Total five models are considered for the analysis i.e. regular building with bare frame, regular building with masonary infill, soft storey building with open ground storey, mass irregular building with masonary infill and vertical geometric irregular building with masonary infill. The non-linear static analysis (pushover analysis) and linear dynamic analysis (response spectrum analysis) are performed for all the models and thereby compare their results. From analysis, the parameters like performance point, time period, maximum storey displacement, maximum storey drifts, storey shears and overturning moments are determined and also comparative study is done for all the models. From the comparison, it is observed that the vertical geometric irregular building shows better performance under seismic loading and bare frame building shows inferior performance. Moreover, the performance of masonary infilled frame building is f

AbstractInpres market block IV Pasar Raya Padang is not designed as a shelter building, but is designated as a vertical evacuation site when a tsunami occurs. This study aims to evaluate the structural performance of Inpress market block IV zone B. The method used for this research is the pushover analysis method. According to FEMA P-646/2019, vertical evacuation refuge structures are included in tsunami risk category IV, based on the risk category the maximum performance level is at the Immediate Occupancy (IO). For loads on buildings, refer to SNI 1727:2020 and SNI 1726:2019 for earthquake loads. For the calculation of the capacity of concrete structural elements, refer to SNI 2847:2019. Structural analysis was carried out using the SAP2000 version 16. After analysis, based on performance points, drift ratio that occur due to earthquake loading in X-direction and Y-direction are 0,05875% and 0,0067%. The maximum total drift that occurs is smaller than that required by ATC-40 for the Immediate Occupancy performance level, which is 1%. Thus, the structure performance level is Immediate Occupancy. This means that the Inpress market block IV building is still strong enough against earthquake loads.

The uncertainties of earthquake currently were not considered with the various lateral load patterns of pushover. The convex set theory, which requires much less information, is employed to model the uncertainties of the seismic influence coefficient maximum and the characteristic period of response spectrum. Then the convex analysis method is integrated into the fundamental equation of pushover, and the analytic relationship of lateral seismic load and top displacement of buildings is derived. The results of numerical example shows that the new lateral load pattern of pushover proposed in this research may effective simulate the uncertainties of strong ground motion.

The two different procedures of ASCE/SEI 41 Supplement 1 and the EC 8 based Greek Retrofitting Code (GRECO) are compared via pushover analyses for the seismic assessment of RC buildings designed to old codes. In addition, the FEMA 356 procedure is considered in order to evaluate the new provisions of ASCE/SEI 41. Results from two moderate level seismic tests performed on a four-story building are used for comparison. For the first test, all procedures overestimated the experimentally observed limited damage but GRECO was more satisfactory. For the second higher excitation test, all procedures predicted the building's high vulnerability but failed to predict the experimentally observed imminent collapse of a stiff column. In all cases, GRECO gave higher displacements. ASCE/SEI 41 and FEMA 356 predicted better the building's stiffness and gave much higher available plastic hinge rotations for beams when compared to GRECO. Concerning the columns, available plastic hinge rotations at the Life Safety performance level from the ASCE procedure were higher than GRECO, while ASCE values at the collapse prevention performance level were slightly lower than GRECO. Finally, a comparison of the above procedures with nonlinear dynamic analyses of a past earthquake is performed to identify potential pushover analysis concerns.

Pada proses pembangunan gedung SMP 3 Muhammadiyah Yogyakarta terjadi permasalahan internal yang mengakibatkan proses pengerjaan berhenti sementara dan terjadi pergantian kontraktor. Ketika pembangunan kembali dilaksanakan, assesment pada gedung diperlukan untuk mengetahui mutu beton. Pada pengerjaan proses assesment terdapat kesalahan prosedur yang mengakibatkan struktur dari bangunan mengalami kerusakan. Beberapa tulangan utama dari struktur kolom terputus dikarenakan proses core drill. Melihat permasalahan tersebut pemeriksaan terhadap evaluasi kinerja struktur perlu dilakukan. Metode yang digunakan dalam pemeriksaan evaluasi kinerja struktur adalah pushover analysis yang disesuaikan dengan pedoman ATC-40. Output dari pushover analysis adalah level kerusakan bangunan. ATC-40 merupakan salah satu pedoman yang digunakan dalam penentuan level kerusakan. Level kerusakan yang dihasilkan dapat digunakan sebagai evaluasi keamanan struktur setelah terjadi gempa. Berdasarkan pushover analysis yang telah dilakukan didapatkan nilai performance point sebesar Sa= 0,091 dan Sd= 0,017 untuk push x sedangkan untuk nilai dari push y adalah Sa= 0,089 dan Sd= 0,016. Sedangkan untuk nilai maksimum total drift 0,00113 dan nilai maksimum inelastic drif 0,00095 pada push x dan nilai maksimum total drift 0,00128 dan nilai maksimum inelastic drif 0,001036 pada push y. Berdasarkan hasil tersebut didapatkan level kerusakan struktur adalah Immediate Occupancy (IO) yang artinya apabila terjadi gempa, hanya sedikit kerusakan struktural yang terjadi. Karakteristik dan kapasitas sistem penahan gaya vertikal dan lateral pada struktur masih masih sama dengan kondisi dimana gempa belum terjadi, sehingga bangunan aman dan dapat langsung dipakai.
