In this study, the
lattice roof model was designed in 3 dimensions using the finite element method
in the Ansys package program. This method can be understood by making the
complex engineering applications is a method to provide the solution can be
controlled by the system. The element type of the model, the outside diameter
of the truss pipe, the thickness of the meat, the modulus of elasticity and the
poisson ratio parameters are defined as material properties. The material is a
steel isotropic material. A total of mechanical and elastic stress analyzes
were carried out under the constant load of 25000 and 20000 kN applied to Fx,
Fy, Fz beam axes and 2 MPa pressure on the 3D lattice
roof model. Deformations of the model against the load were investigated by
analyzing the stresses against the mechanical forces and the elastic stresses
in the x, y, z axes. As a result of the analyses, it was observed that the
mechanical and elastic stresses in the beam axes against the applied load
increased.

Bu çalışmada, kafes çatı
modeli Ansys paket programında, sonlu elemanlar yöntemi kullanılarak 3 boyut
olarak tasarlandı. Bu yöntem, kompleks mühendislik uygulamalarının
anlaşılabilir hale getirilerek, kontrol edilebilir sistemlerle çözümünü
sağlayan bir metottur. Modelin element tipi, kafes boru dış çap, et kalınlığı,
elastisite modülü ve poisson oranı parametreleri malzeme özelliklerine
tanımlanır. Malzeme çelik izotropik bir malzemedir. 3D kafes çatı modeline Fx,
Fy, Fz kiriş eksenlerine uygulanan 25000 ve 20000 kN’luk
sabit yük ve 2 MPa basınç altında toplam mekanik ve elastik gerilme analizleri
yapıldı. Modelin x, y, z eksenlerinde mekanik zorlanmalara karşı gerilme ve
elastik stres gerilme analizleri yapılarak yüke karşı göstermiş olduğu
deformasyon şekil değişimleri incelendi. Analizler sonucunda, uygulanan yüke
karşı oluşan kiriş eksenlerindeki mekanik ve elastik gerilmelerin arttığı
görüldü.
