Developing cyclic loading protocols for regions of low to moderate seismicity

چکیده
This paper deals with the development of loading protocols appropriate for cyclic testing in regions of low to moderate seismicity in Europe. To serve this goal, cumulative damage demands imposed by a set of 60 ground motion records, representative of a European moderate seismicity region for the 2% probability of exceedance in 50 years seismic hazard level, on a wide variety of SDOF systems are evaluated. To meet the calculated cumulative damage demands, several loading protocols are developed for different structural types, vibration periods and level of reliability (medians or 84 percentiles). Protocol comparisons reveal that the proposed loading protocols for the median estimates of cycle amplitudes are significantly less demanding than existing protocols. Consequently, they can result in more cost-effective structural configurations in European regions of low to moderate seismicity.

Loading Protocols for European Regions of Low to Moderate Seismicity
Existing loading protocols for quasi-static cyclic testing of structures are based on recordings from regions of high seismicity. For regions of low to moderate seismicity they overestimate imposed cumulative damage demands. Since structural capacities are a function of demand, existing loading protocols applied to specimens that are representative of structures in low to moderate seismicity re...
متن کاملSensitivity of Drift Capacities of Urm Walls to Cumulative Damage Demands and Implications on Loading Protocols for Quasi-static Cyclic Tests
Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of quasistatic cyclic tests. This paper shows that for URM walls failing in shear the number of applied cycles in quasi-static cyclic tests influ...
متن کاملLoading Protocols for Structures Designed for Different Behaviour Factors
All the existing loading protocols have been developed independently of the value of the behaviour factor q that the structure has been designed for. Conservatively, a single loading protocol is adopted, for all q values, based on the structural system with the most onerous cumulative seismic demands. However, analyses conducted by the authors, show that imposed cumulative seismic demands decre...
متن کاملLife-cycle Cost Analysis for the Seismic Isolation of Bridges in a Region of Low to Moderate Seismicity
A nonlinear approach for the life-cycle cost (LCC) analysis is proposed. Computational procedure for the analysis of LCC for seismically isolated bridges in a region of low to moderate seismicity is established. To compute the failure probability of critical structural components, most probable failure modes for the structure-isolator system are defined as unseating failure of a superstructure,...
