Recording Characteristics of the K-NET95 Strong-motion Seismograph

ESTIMATING THE STRONG-MOTION OF THE DECEMBER 26, 2003 BAM (IRAN), EARTHQUAKE USING STOCHASTIC TECHNIQUES

  Abstract : The main objective of this study is estimating the strong motion for the Bam region using the stochastically based seismological models. The two widely used synthetic techniques namely point-source and finite-fault were utilized incorporating the source-path and site parameters into simple function. The decay factor kappa was estimated based on the data obtained from recorded stron...

Dynamic Characteristics of Buildings Estimated from Strong Motion Records

Estimation of the dynamic characteristics of buildings is a key issue in seismic design technology. Since 1957, the Building Research Institute (BRI), Japan, has been operating a network to monitor strong motion in buildings. In this study, dynamic characteristics of 25 actual buildings in the BRI network were estimated by using strong motion records. Acceleration records from two sensors respe...

a 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...

Establishment of a Long-period Seismograph Network Utilizing Magnetic Tae Recording

Strong Motion Data Processing and Recording at University of Southern California

A brief review is presented of the Los Angeles and Vicinity Strong Motion Network operated by the University of Southern California (USC), consisting of 80 stations deployed in 1978-1980, and of software developed and used at USC for digitization of accelerograms recorded on film, and for routine and specialized data processing of digitized or digitally recorded accelerograms. The currently use...
