Parametric Characterization of RC Bridges for Seismic Assessment Purposes

“…The fundamental period of vibration becomes also handy to e.g. carry out proper selection of records according to recent methodologies, such as the conditional spectrum method, also successfully applied to bridges [32,33]. Such a selection guarantees reliable performance points for any employed nonlinear static procedure or seismic input for nonlinear dynamic analyses.…”

“…The derivation of fragility curves from a number of relevant geometrical or structural parameters taken from real case studies is of utmost importance for the accuracy of loss assessment investigations as part of decision-making strategies [31][32][33]. In such way, civil protection or other expert bodies can rely on them during the management of postextreme event emergency phases.…”

Seismic Response of Rc Bridges Using Generalised Force Vectors

“…This was achieved by calculating the Normalized Root Mean Square Deviation (NRMSD), at a location j, according to Equation (17), where the RMSD at a location j is defined in Equation (18). In the equation, n represents the number of records.…”

“…Correspondingly, the NSPs that incorporate higher mode effects provide a response that is more accurate, especially in structures where higher mode contributions are expected to be important [13][14][15]. Single mode based NSPs on the other hand typically present shortcomings for structures where higher mode effects are important, but they do tend to provide acceptable or good estimates for regular structures and may represent a good compromise for large scale assessment studies [16][17].…”

Towards a Taxonomy for Portuguese Rc Bridges

“…structures that have to be retrofitted or to conduct the prioritization schemes in terms of use of available resources. Application wise, the proposed taxonomy will find room in webGIS software platforms for the real time seismic risk assessment of infrastructure networks [6,7], to be used by different stakeholders, such as decision makers, practitioners, insurance and reinsurance companies, amongst others.…”
