10-) Deprem Takozu

Owned by Gokhan Alkan (Unlicensed)
Last updated: Feb 21, 2019 by Seda Ozdemir (Unlicensed)

Deprem takozu, küçük ve orta büyüklükte köprülerde ana taşıyıcı kirişler (öngermeli I kiriş) arasında, altyapı yüzeyinde (başlık kirişi ya da kenarayak) konumlanır. Deprem takozunun kullanım amacı, orta büyüklükteki depremlerden ya da çeşitli servis yüklerinden kaynaklanan köprü enine yatay hareketini sınırlandırmak ya da tamamen engellemektir. Deprem takozunun düşey yük dayanımı ve aktarımında rolü yoktur.

Gerekli Parametreler

  • Kirişi seçimi (Girder)

                 Hangi kirişi referans alması gerektiğini belirtir.

  • Kiriş ile takoz arasındaki mesafe (spacing) (cm)

                 Deprem takozu için seçilen kirişe olan mesafesini belirtir.

  • İlk deprem takozu genişliği(dt_depth_L)

                 İki altyapı objesine (kenar ayak veya başlık girişi) karşılıklı oluşan deprem takozu objesinin station olarak daha geride olan altyapı üzerindeki genişliğidir. 

  • İkinci deprem takozu genişliği(dt_depth_R)

                 İki altyapı objesine (kenar ayak veya başlık girişi) karşılıklı oluşan deprem takozu objesinin station olarak daha önde olan altyapı üzerindeki genişliğidir. 

  • Takozun yüksekliği (dt_height) (cm)

                 Takozun yukarı yöndeki boyutudur.
