Investigation of seismic performance.of buildings with STRP （scrap tire rubber pad） seismic isolators by means of pseudo-dynamic tests and numerical simulation is presented. The isolated building is numerically modeled, while the base isolation layer is considered as the experimental substructure in the pseudo-dynamic tests. The test result verifies that the STRP isolator shows acceptable shear deformation performance.predicted by the design methods, and demonstrated that seismic isolation using STRP works as a protective measure to provide enhanced seismic performance.of the building indicated by the reduction of top floor absolute acceleration, drift and base shear as designated.

关键词： Pseudodynamic test STRP isolator numerical simulation base isolation seismic performance.

Estimation of Concrete Arch Dams Responses in Linear Domain Using Endurance Time Analysis Method

引用

Journal of Civil Engineering and Architecture 2011年第8期5卷 754-758页

In this paper, Endurance Time Analysis （ETA） method which is a new time-history based dynamic pushover procedure is introduced and its application in linear analysis of concrete arch dams is investigated. In this method the structure is subjected to gradually intensifying acceleration functions and its performance.is evaluated based on the length of the time duration that can satisfy required performance.criteria. For this purpose Dez arch dam is selected as case study, fluid-structure interaction is taken into account and F.E. model of the system is excited in three performance.levels. ETA method gives an approximation of maximum response at the equivalent target time, resulted from analyzing the system based on natural records. Extracted results are displacement, velocity and acceleration of the crest at crown cantilever. Results show using of ETA method can reduce at least 50% in number of analyses and 70% in total time of analyses at the current case. Furthermore, it is found that although the results of the ETA are not exactly consistent with the results of time-history analyses using real ground motions, errors are reasonable and ETA can identify performance.levels of the dam with acceptable accuracy.

关键词： Endurance time analysis linear response arch dam seismic performance.
