摘要:
Researches on the cause of formation and attributes of some near-fault earthquake ground motion characteristics such as directivity effect, fling-step effect, hanging-wall effect and prominent vertical ground motion are briefly introduced; the research progress of seismic responses of engineering structures induced by near-fault horizontal and vertical seismic ground motions are summarized separately and comprehensively. The seismic resistant design guidelines or codes considering the engineering effect of near-fault ground motions all over the world is introduced on the basis of the investigation of seismic behavior of engineering structures imposed by near-fault motions. Further investigation on the formation mechanism of pulse attribute resulted from near-fault hanging-wall effect and stochastic property of near-fault motions should be conducted in future. Confirmation and validation should be performed on the safety and effectiveness of structural vibration control technology imposed on engineering structures excited by near-fault motions. It is recommended that seismic responses of engineering structures imposed on acceleration pulse, vertical and rotational components should be paid more attention. Numerical simulation technology of formation and development process of the seismogenic fault can be employed to remedy the lack of near-fault seismic records and to investigate near-fault seismic attributes and engineering structural responses. It is believed that the summarization and discussion in this paper will provide references for considering the influence of near-fault effects and criterion modification of future engineering design and evaluation. ©, 2014, Science Press.
