Vulnerability evaluation and seismic rehabilitation of steel building with semi-rigid connections (Case study - tehran)
In this paper, the seismic rehabilitation of a steel building with semi-rigid connections in Tehran is presented. This building with 19 stories in three blocks and an asymmetric plan has been constructed 30 years ago. First step of the rehabilitation study includes qualitative vulnerability evaluation which indicates that the building has heavy seismic vulnerability potential. In the second step, quantitative vulnerability of the structure according to FEMA 356 guideline is evaluated. The results showed that the building is resistant enough against gravity loads but not safe enough for seismic loads. Finally, two seismic retrofitting plans consisting of concrete shear walls and steel shear walls are proposed. Comparison of retrofitting plans of the building from seismic performance, architectural and implementation aspects showed that the concrete shear walls plan is the superior choice.
