INTRODUCTION There exist some 361 strong motion accelerographs in Turkey. About 158 accelerographs (40% analog, 60% digital) are owned and operated by Earthquake Research Department (ERD) of Ministry of Public Works as the national strong motion network distributed all around Turkey. About 200 digital strong motion accelerographs are owned and operated by Kandilli Observatory and Earthquake Res...

time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. one of the important issues in the time-history analysis is selecting earthquake records. in this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. a...

The present work is concerned with the introduction of a new first level pre- and post-earthquake seismic assessment protocol for buildings that relies on use recorded structural response. As earthquakes represent constant unpredictable threat building stock around globe, protocols already in assessing risk should be revised also take into account information hidden data field. Nowadays, collec...

Tile need for a greatly expanded network of strong-motion accelerographs throughout the seismic regions of the world is stressed. A summary of the characteristics of currently available strong-motion accelerographs is presented, and the design details are given for an instrument suitable for acquiring the basic data needed by structural engineers for earthquake resistant design. It is shown tha...

The modern techniques for digitization of strong-motion accelerograms and subsequent data processing were first developed in the late 1960s and early 1970s, at which time the only available digitization technology was semi-automatic hand digitization. Following the development of image processing technologies in the early 1970s, an automatic digitization and data processing system, driven by a ...

A comprehensive database that has been used to develop ground motion models for induced earthquakes in the Groningen gas field is provided a freely accessible online repository. The includes more than 8500 processed recordings from 87 of local magnitude M L between 1.8 and 3.6, obtained large network surface accelerographs borehole geophones placed at 50 m depth intervals 200 m. 5%-damped pseud...

Abstract Small-magnitude earthquakes induced by gas production in the Groningen field Netherlands have prompted development of seismic risk models that serve both to estimate impact these events and explore efficacy different mitigation strategies. A core element modelling is ground-motion prediction (GMPM) derived from an extensive database recordings obtained a dense network accelerographs in...
