Pushover Analysis Of Retrofitted Reinforced Concrete Buildings, Hamidreza Nahavandi
Pushover Analysis Of Retrofitted Reinforced Concrete Buildings, Hamidreza Nahavandi
Civil and Environmental Engineering Master's Project Reports
For the past decade or more, the structural engineering profession has been using the nonlinear static procedure (NSP) or pushover analysis. Modeling for such analysis requires the determination of nonlinear properties of each component in the structure, quantified by strength and deformation capacities, which depend on the modeling assumptions. Pushover analysis is carried out for either user-defined nonlinear hinge properties or default-hinge properties, available in some programs based on the FEMA-356 such as SAP2000. While such documents provide the hinge properties for several ranges of detailing, programs may implement averaged values. In the realm of retrofitting of existing structures, few …
