Full-text available
This presentation contains a finite element simulation for masonry walls under cyclic loading.
Conference Paper
The use of glass units as facade cladding in modern buildings has become a common practice. These units are generally formed as double or triple plates by dry air or another gas (argon, etc.) between the plates to provide heat insulation. This makes the engineering design under the wind and thermal loading difficult, since one must consider the for...
Conference Paper
Structural members can be designed using more slender sections thanks to the developing structure and material technology. This makes it important to consider the concept of stability in the design of structures. In the present paper, stability behavior of distributed loaded Timoshenko beams resting on elastic foundation are investigated. A mixed f...
Conference Paper
Masonry structures are one of the most complex structures in terms of anisotropic behavior of their masonry units and mortar assemblages. In the present study, nonlinear behaviors of masonry walls with different brick bond styles are modeled and analyzed. Heterogenous masonry modeling technique is used for modeling of masonry walls. Modeling is per...
Conference Paper
Masonry is a composite material that consists of masonry units (brick, stone etc.) and mortar. Modeling of the composite structure of masonry materials require advanced modeling techniques. In the present study, masonry units and mortar are modeled using continuous micro modeling technique. ANSYS® Academic Research Mechanical, release 18.0 software...

Arch dams have strong structural behavior because of their arch geometry. Numerical analysis of the arch dams is a necessary not only to validate the structural performance of the existing arch dams but also to model and analyze modern dam constructions. Finite element models for the arch dams are generally very complicated in terms of having many...

Masonry structures are constructed by joining masonry units (brick, stone, marble etc.) with mortar. Various methods are used for modeling of masonry walls of the structures. Micro modeling and Macro modeling are two diverse modeling techniques. In this study, these two modeling strategies are analyzed on a solid unreinforced masonry shear wall num...
Conference Paper
The use of glass for exterior façade has been becoming increasingly popular, as it offers more light to the inhabitants and gives an aesthetic view to the building itself. Due to the increase in glass demand, sophisticated engineering analysis comes into question in the design for optimization purposes. It is a well-known fact that, accounting for...

Plates are widely used structures with one size being much smaller than two others. It is known that the loads on the plates are perpendicular to the plate surface. In today's structures, annular plates are designed according to the purpose of use such as storage tanks, machine industry and many engineering areas. In this study, numerical large def...
Conference Paper

A flat 4 node shell element superposing plate bending and membrane components is developed which takes 6 degrees of freedom (DOF) per node. Normally, shell elements possess 5 degrees of freedom, three translational and two rotational, each being in-plane, per node. A sixth DOF is associated with shell normal rotation via imposing an arbitrary out-o...
