Simulation of Strong Ground Motions
The estimation of potential strong ground motions at short epicentral distances (J1 = 10 to 25 km) resulting from large earthquakes, M;;;; 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set from smaller magnitude earthquakes. The simulatio...
متن کاملa generalization of strong causality
در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...
Non-linearity and temporal changes of fault zone site response associated with strong ground motion
S U M M A R Y We systematically analyse temporal changes of fault zone (FZ) site response along the Karadere-Düzce branch of the North Anatolian fault that ruptured during the 1999 İzmit and Düzce earthquake sequences. The study is based primarily on spectral ratios of strong motion seismic data recorded by a FZ station and a station ∼400 m away from the fault and augmented by analysis of weak ...
متن کاملEvaluation of Nonlinear Response of Structures to Near-Fault Ground Motions and the Comparison of Results with Near-Fault Simulated Records
Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...
متن کاملAppraising Weak and Strong Sustainability: Searching for a Middle Ground
This paper seeks to address the issue of weak and strong sustainability as well as the search for a middle ground. It discusses the differences between weak and strong sustainability while arguing for the harmonisation of both nature and humankind. Achieving harmony requires a move towards an idealist eco-sociofeminist point of view. Through this, full equality and balance may be attained.
