Deprem esnasında yapıda oluşan yapısal ve yapısal olmayan hasarlar genellikle sistemde oluşan yatay deplasmanlardan meydana gelmektedir.   Günümüzde kullanılan geleneksel kuvvet esaslı dizayn metodunda deplasmanlar dizaynın sonunda kontrol edilirler.  Bu nedenle potansiyel hasarların kontrol edilmesi çok güçtür. Yapıların hedef bir deplasman için dizayn edildiği deplasman esaslı dizayn yöntemi ile yapının hasar potansiyeli kontrol altında tutulabilmektedir. Deplasmanlar, direkt deplasman esaslı dizayn metodunun temelini oluşturmaktadır.  Moment aktaran çerçeve tipi yapıların direkt deplasman esaslı dizaynı için iki farklı deplasman profili önerilmiştir.  Bu çalışmada lineer olmayan dinamik analiz kullanılarak dört, altı ve on katlı moment aktaran çerçeve yapılar için deplasman profilleri elde edilmiştir.

Dısplacement Profıle For The Dısplacement Based Desıgn Of Moment Resıstıng Frames

Damages that occur in structural and non-structural elements during the earthquakes are due to lateral displacements.  Traditional force based design methods control displacements at the end of the design.  Therefore, it is difficult to control potential damages.  Direct displacement based design approach that designs the structure for a given displacement profile, can control the potential damages.  Direct displacement based seismic design uses the displacement profile as the basis of the design approach.  Two different displacement profiles proposed for the direct displacement based seismic design of moment resisting reinforced concrete frame structures.  In this study displacement profiles for four, six and ten storey moment resisting frames are determined by using nonlinear time history analysis.
