Weekly Schedule

1) Contents of Engineering Seismology, hazards associated with earthquakes: ground shaking, structural hazards, liquefaction, landslides, tsunamis The sources of seismic activities causes the damages in a region. Geological, geophysical and geodetic indicators for seismic hazards. Geological Evidences: Movements near the ground surface, topographic and geomorphic indicators, changing in ground water levels Geophysical Evidences: Fault activity, active fault, inactive fault, tectonical evidences, historical and instrumental seismicity. Geodesical Evidences: Fault movements appearing in geodetic surveys, changes in the distance between fixed points
2) The characteristics of the ground motion that are of engineering significance and to identify a number of ground motion parameters Evaluation of the effects of earthquakes at a particular site requires objective, quantitative ways of describing strong ground motion. Strong ground motion measurement, Accelorometers, data acquisition and digitation, strong motion processing, strong motion instrument arrays
3) The characteristics of strong ground motion in quantitative form
4) Estimation of ground motion parameters Magnitude, distance and local geology effects, Predictive relationships of strong ground motion
5) Seismic Hazard Analysis: Quantitative eatimation of ground shaking hazards. Sismik Tehlike Analizleri: Belirli bir sahadaki yer sarsıntısı tehlikesini nicel olarak hesaplanması. Deterministic seismic hazard analysis: The development of a particular seismic scenario upon which a grouund motion hazard evaluation. Identification of geometry of the seismic sources, Selection of a source to site distance
6) Probabilistics seismic hazard analysis: The consideration of probabilistic concepts allowing uncertainities in the size, location, and a rate of recurrence of earthquakes and in the variation of ground motion charecteristics. Identification of seismicity and recurrence period of earthquakes in the seismic sources The ground motion produced at the site by earthquakes of any possible size occurring an any possible point Uncertainities in the earthquake location, earthquake size and ground motion parameter The acceleration level with a probability of being exceeded
7) Ground Response Analysis:The prediction of ground surface motions for development of design response spectra, to evaluate dynamic stresses and strains for evaluation of liquefaction hazards and to determine the earthquake induced forces One-dimensional ground response analysis Soil-Structure Interaction Charesteristics period of a site.
8) Midterm examination/Assessment
9) Design ground motions and design spectrums Earthquake resistant design of new structures and evaluation of the safety of existing structures requires anaysis of their response. The level of shaking for which satisfactory performance. The comparisons of design spectrums and earthquake spectrums.
10) Identification of liquefaction and liquefaction types
11) Seismic Slope Stability, Earthquake Induced Landslide Activity, The factors which effects the stability of Slope, Seismic Slope Stability Analysis ( Inertial Instability and Block analysis).
12) Turkish Earthquake Code, Minimum conditions of soil parameters for earthquake-resistant, Examples from the international codes (Uniform Building Code, Eurocode, NEHRP), The comparisons of the codes and design spectrums.
13) Geopgysical Testing techniques for soil improvement, Stifness Measurements, Cross hole and down hole tests, Measuring P and S velosities, Sismic reflection and seismic refraction tests.
14) The sources of microtremors (earthquakes with a small magnitudes, cultural noises, ocean waves, geotermal reactions, traffic, industrials machines), General features of microtremors(periods, amplitudes, waveforms), The analysis of microtremor records (Spectral ratio ana Nakamura method).
15) The integration of seismic hazards associated with the local site effects. Maps representing regional geographic, geologic, geophysics and geotechnics information Overlapping and combining the various hazard effects.
16) Final examination
