EFFECT OF SEISMIC LOADING TO PREFABRICATED CONNECTIONS

Abstract

Most of industrial buildings are prefabricated structures and built on high seismic risk zones. Prefabricated buildings must be earthquake resistant which can be possible if structural elements and their connections are properly built. In recent years, prefabricated buildings which have no RC walls were damaged heavily during arthquakes. In this paper, prefabricated industrial structures, damaged during Ceyhan (1998), Kocaeli (1999) and Düzce (1999) earthquakes, and reasons of structural damages are studied. Additionally design and construction precautions are given for building an earthquake resistant prefabricated structure.

Abstract

Endüstriyel yapıların çoğu prefabrik yapılardır ve yüksek sismik risk altında olan bölgeler üzerine inşa edilmişlerdir. Bu yüzden prefabrik yapılar depreme dayanıklı olmak zorundadır ve bu ancak yapı elemanlarının ve bunların montaj detaylarının uygun olması ile mümkündür. Son 10 yılda, betonarme perdesi olmayan prefabrik yapılar depremlerde ağır hasarlar görmüşlerdir. Bu çalışmada; Ceyhan (1998), Kocaeli (1999) ve Düzce (1999) depremlerinde hasar görmüş prefabrik endüstriyel yapılar ve oluşan yapısal hasarların sebepleri araştırılmıştır. Ayrıca depreme dayanıklı bir prefabrik yapı inşa etmek için alınması gereken önlemler projelendirme ve imalat aşamaları için verilmiştir
