Abstract: | An important advancement in earthquake engineering has been the development of
performance-based concepts for the seismic design of structures. Performance-based
seismic design approaches overcome the shortcoming of the traditional force-based
approach. The first step in the Direct Displacement-based Seismic Design (DDBSD)
procedure is the definition of the target displacement that the building should not
exceed under a given seismic hazard level. Indeed, the procedures require inelastic
analysis.
Direct Displacement-Based Seismic Design procedures appeared in recent seismic
design codes (e.g., EC 8, etc.) in addition to the traditional forced-based approach. The
design of several buildings via EC 8 Displacement Based approaches and traditional
forced-based approaches will be discussed in this thesis.
Low-Rise, mid-rise, and high-rise RC has been designed based on both approaches.
Seismic Performance levels of the designed buildings have been re-evaluated via the
nonlinear dynamic analysis procedure. The effect of design strategy on the
performance and cost of each type of building have been compared. Building
performance has slightly increased in terms of displacement. Furthermore, a
considerable amount of improvements has been observed in plastic hinge formations.
On the other hand, the cost difference between the two methods was acceptable. ÖZ:
Deprem mühendisliğindeki önemli bir gelişme, yapıların sismik tasarımı için
performansa dayalı konseptlerin geliştirilmesi olmuştur. Performansa dayalı sismik
tasarım yaklaşımları, geleneksel kuvvet temelli yaklaşımın eksikliklerinin üstesinden
gelir. Doğrudan Deplasmana Dayalı Sismik Tasarım (DDBSD) prosedürünün ilk
adımı, binanın belirli bir sismik tehlike seviyesi altında aşmaması gereken hedef yer
değiştirmenin tanımlanmasıdır. Gerçekte, prosedürler plastik ozellikleri goz onunde
bulunduran analiz gerektirir.
Doğrudan Deplasmana Dayalı Sismik Tasarım prosedürleri, geleneksel zorunlu
temelli yaklaşıma ek olarak son sismik tasarım kodlarında (örneğin EC 8 vb.) ortaya
çıktı. EC 8 Deplasman Temelli yaklaşımlar ve geleneksel kuvvet temelli yaklaşımlar
aracılığıyla yasarlanan binanin performansi bu tezde tartışılacaktır.
Az, orta ve yüksek katlı RC, her iki yaklaşıma göre tasarlanmıştır. Tasarlanan binaların
sismik performans seviyesi doğrusal olmayan dinamik analiz prosedürü ile yeniden
değerlendirildi. Tasarım stratejisinin her bina türünün performansı ve maliyeti
üzerindeki etkisi karşılaştırılmıştır. Tavan deplasmani açısından bina performansı
biraz artmıştır. Ayrıca, plastik menteşe oluşumlarında önemli miktarda gelişme
gözlenmiştir. Öte yandan, 2 yöntem arasındaki maliyet fark dikkate alinmayacak kadar
ufaktir. |
