Abstract:Due to development of the construction of industrial steel structures containing overhead cranes and by realizing that almost none of the aseismic codes in the world have any notification about special structures of this kind, the importance of studying the seismic behaviour of this kind of structures becomes evident. In this research, the overall structural behaviour and Performance Point determination bases are briefly described. Later, 3 existing models of industrial steel structures with overhead cranes, which are previously analysed and designed by the author of this paper, are selected. Equivalent Linear Static Analyses and structural design of models are completed according to ASCE 7-10, AISE (Association of Iron and Steel Engineers) and SNIP II-6.02 Armenian Seismic Code, considering 4 soil categories of Rock (800<Vs<1200m/s), Dense Soil (360<Vs<800m/s), Loose Soil (180<Vs<360m/s) and Very Loose Soil (Vs<180) respectively, based on spectral acceleration of Sa=0.35g. By performing a Modal Pushover Analysis on all estimated finite element models, the Capacity Curves of them are achieved. Later the Performance Point characteristics (base shear force and roof maximum displacements) of all models are computed according to FEMA 356 guideline recommendation, based on spectral acceleration range of 0.1g~1.0g for above mentioned soil types and using FEMA 356 pseudo acceleration spectrums. After completing the achieved information from modal pushover analysis, the diagrams for both base shear forces and displacements versus spectral acceleration are prepared and the final results are discussed.
