Abstract:

 

Son yıllarda yapısal optimizasyon konusunda yapılan çalışmalar, genellikle yapıların lineer elastik bölgedeki davranışını göz önüne almakta ve lineer olmayan bölgedeki yük taşıma kapasiteleri ihmal edilmektedir. Çelik ve alüminyum gibi hafif yapı malzemeleriyle teşkil edilen uzay çerçevelerde, büyük deplasmanların ve malzeme bakımından lineer olmayan davranışın göz önüne alınmasının önemli bir mühendislik problemi olduğu bilinmektedir. Bu çalışmada, sismik yüklere maruz uzay çerçevelerin, malzeme ve geometrik olarak lineer olmayan davranışları birlikte göz önüne alınarak optimizasyonu yapılmıştır. Çözümler ANSYS paket programının APDL (Ansys Programming Design Language)  kodlama dili yardımıyla alt program yazılarak elde edilmiştir.

 

The studies having been carried out on structural optimization in recent years, generally take into consideration the behavior of the structures in linear elastic region, and the load capacity in non-linear regions are neglected. It is well known that it is an important engineering problem to take into consideration the great displacements and non-linear behavior in terms of material, in space frames, structured with light building materials, such as steel and aluminum. In this study, the optimization of the space frames exposed to seismic loads was carried out by considering their non-linear behaviors both in terms of material and geometry.  The results were obtained by preparing a macro program in the APDL (ANSYS Programming Design Language) coding language of the ANSYS package program.
