{{vector version available|new image name}}.
It is recommended to name the SVG file “PGA Kocaeli.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |

Summary
| Description |
Türkçe: 1999 Kocaeli depremi sırasında kaydedilmiş kaydı gösterilmiştir. Yatay eksen saniye, düşey eksen ise yer çekimi ivmesi göstermektedir. Şekil’de işaretlendiği gibi, maksimum yer ivmesi 0,25 g’dir (~ 2 5 m/s 2).
Sönüm oranı 5 olmak kaydıyla, periyotları farklı 3 ayrı sistemin, söz konusu yer hareketi altında yer değiştirme değerleri zamana bağlı olarak gösterilmiştir. Farklı periyotlar için hesap yapılmasının nedeni, periyodun yapının kütlesi ve rijitliğine bağlı bir parametre olmasıdır. Farklı periyotlara sahip tek serbestlik dereceli sistemleri göz önüne almak, rijitlikleri ve kütleleri farklı tek serbestlik dereceli sistemler için hesap yapmayı sağlar. Şekil’e göre, verilen zemin profilinin PGA, Ambarlı kaydı PGA’nan daha yüksektir.English: The recording recorded during the 1999 Kocaeli earthquake is shown. The horizontal axis is the second, and the vertical axis is the gravitational acceleration. As marked in the figure, the maximum ground acceleration is 0.25 g (~ 2 5 m/s 2).
With a damping ratio of 5, the displacement values of 3 different systems with different periods under the mentioned ground motion are shown depending on time. The reason for making calculations for different periods is that the period is a parameter dependent on the mass and stiffness of the structure. Considering single-degree-of-freedom systems with different periods allows to calculate for single-degree-of-freedom systems of different stiffnesses and masses. According to the Figure, the PGA of the given soil profile is higher than the Ambarlı record PGA.Русский: Показана запись, сделанная во время землетрясения Коджаэли в 1999 году. Горизонтальная ось - вторая, а вертикальная ось - ускорение свободного падения. Как показано на рисунке, максимальное ускорение грунта составляет 0,25 g (~ 2 5 м / с 2).
При коэффициенте демпфирования 5 значения смещения 3 разных систем с разными периодами при упомянутом движении грунта показаны в зависимости от времени. Причина проведения расчетов для разных периодов заключается в том, что период является параметром, зависящим от массы и жесткости конструкции. Рассмотрение систем с одной степенью свободы с разными периодами позволяет производить расчет для систем с одной степенью свободы с различной жесткостью и массой. Согласно рисунку, PGA данного почвенного профиля выше, чем рекордный PGA Амбарлы. |
