Recently, steel structure construction becomes important, in Turkey. Heavy damages and loses in recent earthquakes have an important role in this manner. However, irregularities in plan due to architectural reasons could cause damage. Therefore earthquake resistance of the buildings with irregularities should be investigated. If strengthening is necessary for existing steel structures, practical applications are to be evaluated and it is necessary to determine the most suitable solution. Strengthening of steel structures is very complex as for reinforced concrete structures. In the present study, to investigate the earthquake resistance of irregular steel structures, three different models including irregularities in plan were investigated. Models were strengthened by using shear walls and steel bracings. Nonlinear pushover analyses were used for evaluation. A comparison was made according to the results of the analyses. As a result of the analyses, it is found that, capacity has been increased more with shear walls comparing to bracings.

Planda Düzensizlikleri Olan Çelik Yapıların Güçlendirilme Tiplerinin Değerlendirilmesi

Çelik yapılar, Türkiye'de son yıllarda önem kazanmıştır. Yaşanan depremlerde meydana gelen hasar ve kayıplar bu noktada önemli rol oynamıştır. Bunun yanında çelik yapılarda mimari nedenlerden kaynaklanan planda düzensizlikler olması durumunda bu yapıların da deprem güvenliklerinin incelenmesini önemli bir hal almaktadır. Deprem güvenliklerinin arttırılması gereken durumlarda bu yapıların güçlendirilmesine yönelik pratik uygulamaların değerlendirilmesi ve uygun yöntemin belirlenmesi önemlidir. Betonarme yapıların olduğu kadar, çelik yapıların güçlendirilmesi de karmaşıktır. Bu çalışma kapsamında, planda düzensizliği bulunan çelik yapıların güçlendirilmesinin incelenmesi amaçlanmış ve bu amaçla üç farklı model yapı ele alınarak, perde ve çapraz elemanlarla güçlendirilmiştir. Ele alınan güçlendirme tipleri için doğrusal olmayan artımsal statik itme analizleri gerçekleştirilmiştir. Analizlerin sonuçlarına göre güçlendirme tipleri değerlendirilmiştir. Yapılan analizler neticesinde perde elemanlar kullanılarak yapılan güçlendirme sonrasında elde edilen kapasite artışı çapraz elemanlar kullanılarak elde edilen kapasite artışına göre daha fazla olmuştur.
