seismic performance and loss assessment studies for stock of buildings are generally based on representative models due to extremely large number of vulnerable buildings. the main problem is the proper reflection of the building stock characteristics well enough by limited number of representative models. this study aims to provide statistical information of structural parameters of turkish bui...

A method for displaying prestack seismic data that highlights azimuthal anisotropy is shown. Observations of azimuthal anisotropy in prestack seismic data using this and other methods make it clear that azimuthal anisotropy is observed in all types of seismic data, land, marine and multicomponent and it is widespread, from the shallowest to the deepest reflectors. Consequently, anisotropy must ...

Using all available subsurface information in the design of a 3-D seismic survey, we can better adjust the acquisition effort to the demands of illumination of the target horizon. I present a method that poses the choice of the acquisition parameters as an integer optimization problem. Rays are shot from grid points on the target reflector at uniform opening and azimuth angles and their emergen...

The interpolation and reconstruction of missing traces is a crucial step in seismic data processing, moreover it also highly ill-posed problem, especially for complex cases such as high-ratio random discrete missing, continuous fault-rich or salt body surveys. These are rarely mentioned current works. To cope with cases, we propose Multi-Dimensional Adversarial GAN (MDA GAN), novel 3-D framewor...

Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...

S U M M A R Y Thermally activated, viscoelastic relaxation of the Earth’s materials is responsible for intrinsic attenuation of seismic waves. Seismic observations have been used to define layered radially symmetric attenuation models, independent of any constraints on temperature and composition. Here, we interpret free-oscillation and surface wave attenuation measurements in terms of physical...

Extracting fault, unconformity, and horizon surfaces from a seismic image is useful for interpretation of geologic structures and stratigraphic features. Although interpretation of these surfaces has been automated to some extent by others, significant manual effort is still required for extracting each type of these geologic surfaces. I propose methods to automatically extract all the fault, u...
