Seismic response to sea‐floor diffractors

SEG Technical Program Expanded Abstracts 1983, 1983
The range and resolution capability of the seismic reftection method is ultimately restricted by noise phenomena. The desired signal component in a conventional seismic record corresponds to compressional waves reftected from depth in response to compressional forces induced at the shot point.

Seismic response of structures by the response spectrum method

Nuclear Engineering and Design, 1981
Abstract The problems of the acceleration profile at the lower elevations of cantilever structures and the response of relatively rigid structures are explored. It is shown that the use of the conventional methods for the above problems provide very approximate results.

Correlation of Seismic Responses of Structures

Journal of Structural Engineering, 1997
A practical analytical study is reported that leads to an improved definition of the correlation coefficient for seismic responses of structures. In contrast to definitions currently available, including the widely used expression developed for white-noise excitations by Der Kiureghian, the solution for the correlation coefficient reported in the ...

Vertical Seismic Response Spectra

Journal of the Power Division, 1976
Response spectra are derived from 30 historical vertical motion accelerograms recorded on hard or rock sites and used as a basis for a recommended design response spectra. Accelerograms were corrected for baseline and instrument errors using routine processing methods.

Seismic Response of Isolated Bridges

Journal of Bridge Engineering, 2004
The response of bridges seismically isolated by lead-rubber bearings (L-RB) to bidirectional earthquake excitation (i.e., 2 horizontal components) is presented. The force-deformation behavior of L-RB is considered as bilinear, and the interaction between the restoring forces in 2 orthogonal horizontal directions is duly considered in the response ...

Seismic Response of Storage Racks

2020
Sliding at the base of structures is an excellent source of deformability and damping. This chapter discusses sliding between the structure and its contents. In Chaps. 3 and 4, flexural yielding in building frames, with fully restrained connections, was shown to significantly increase their damping and deformability.

Transmitting Boundaries and Seismic Response

Journal of Geotechnical Engineering, 1985
A parametric study of the seismic response of a chosen site was conducted to demonstrate the obvious inconsistencies in computed ground response as a result of different assumptions made on the transmitting boundary for the site. The cause of these inconsistencies in computed response is the departure from the ideal assumption that the soil deposit ...

The Model of Bounds on Seismic Responses

Applied Mechanics and Materials, 2012
Seismic excitation of linearly elastic structures is dealt with in the paper. It is well known that dynamical structural response is very sensitive to random fluctuations of the excitation; the consequence is that the identification of the forcing function on the basis of a few global parameters does not allow to predict exhaustively stresses in ...
