Seismic behavior of the contents of seismically isolated buildings

, 2021
Sismik izolasyon, gelişmekte olan depreme dayanıklı bir tasarım teknolojisidir. Özellikle ankastre binalara kıyasla kat ivmelerini azaltır. Böylece, binaların içeriğini korumada çok başarılıdır. Önceki çalışmalarda, içerik korumanın kapsamı yalnızca kat ivmelerinin incelenmesi ile yapılmıştır.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

Deep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Seismic Design of Grana Cheese Cold-Formed Steel Racks

Buildings, 2020
Since few years ago only one typology of racks was used to store Grana cheese wheels for aging, which was designed focusing on the sole static behavior. Battened steel columns made by vertical tubes welded to horizontal angles were connected by means of ...

Seismic Behavior of Suction Caisson Foundations

, 2019
Increasing population growth requires more sustainable development of energy. This non-contaminated energy has an inexhaustible energy source. One of the vital parameters in such structures is the choice of foundation type. Suction caissons are now used extensively worldwide for offshore wind turbine.
