Investigation of Seismic Vulnerability of Reinforced Concrete Frames Equipped with Steel Plate Shear Walls
There are various methods for assessing the seismic vulnerability of buildings that vary in cost and accuracy. Fragility curves, which consider the probability of structural damage as a function of ground motion characteristics and design parameters, are more common. These curves express the percentage probability of the structural response exceeding the functional limit at different seismic intensities. The FEMA-P695 analytical method evaluates the existing uncertainty in assessing the seismic behavior of structures with collapse fragility curves. In this research, the seismic vulnerability of a relatively new system of reinforced concrete frames reinforced equipped with steel plate shear walls using the method, relationships and criteria proposed by FEMAP695 in four short, intermediate, tall structural models with 4, 8, 12 and 24 stories has been evaluated under records proposed by FEMAP695. The results of this study and evaluation of effective parameters in the assessment of collapse safety margin show that in general, the reinforced concrete frame equipped with steel plate shear wall has a good performance against earthquake and maximum earthquake probability.
