GDEE-Based Seismic Response Analysis and Reliability Evaluation of Structures

Abstract eng:
GDEE-based seismic response analysis and reliability evaluation of structures are outlined. The stochastic ground motion can be represented by a random Fourier function where basic random variables are involved via the physical stochastic model. The principle of preservation of probability can then be applied to the augmented system composed of any arbitrary physical response quantities related to the system and the basic random parameter set. A family of generalized density evolution equation can thus be derived and solved using numerical methods. Further, introducing appropriate virtual stochastic process, the extreme value distribution of response of the system can be obtained and thus the dynamic reliability and the global reliability can be evaluated by a simple one-dimensional integral. The approach is applied to seismic response analysis and reliability evaluation of a practical structure located in a city where the seismic fortification intensity is 8 degree. The reliabilities of the structure with and without vibration mitigation system are compared.
