At first, glass was only used for covering the surfaces. But nowadays, it is used as carrier member such as column and beam as well. Although so many study were done about behavior of glass under loads, unfortunately we couldn't find any source that is beneficial for us in Turkey. Therefore we collaborated with İTÜ Earthquake Engineering Laboratory to do a range of experimental studies.
We specially sought answer of questions below
• Carrying capacity of glass material under bending moment
• Carrying capacity of glass material under shear force
• Carrying capacity of connection members
• Deformation of glass material under load
• Lateral buckling effect on carrying capacity
• Consisted stresses and deformations on the columns under the axial force

Load transfer and bonding of glass surfaces to metal surfaces by acrylic-based adhesives is one of our commonly used method. Relation between surface area and tensile-shear strength is analyzed by different special samples that are prepared to determine the load carrying capacity of acrylic-based adhesives.
In spider systems, load is usually transferred to spider and main system over one hole by means of ball joints. In this study experimental works were done such as analysis of stresses around hole, effect of lamination defect on load transfer, what can be done to improve edge of hole.
In case of connecting glass materials which are under the axial load, it is very common situation to transfer the load trough bolts. These experiments were done for determination of how more than one bolt share the load and comparison of occurred stresses on glass in real cases to software static analysis results.
Tape shaped products have been started to use as well as acrylic-based liquid adhesives. These products distinguish with their some features such as adhesion to rough surfaces, strength of solvent and UV. We did a series of experiment in order to find out where can these products be used especially in facade sector and their load carrying capacity when they are used with our standard materials. We specially sought answer of the question “how does increasing of adhesion area affect the load carrying capacity”.
We needed to adhere stainless material in order to use it in one of our project. These experimental studies were done to check the resemblance between computer analysis results and real behavior of material.
We did some experimental studies to find load carrying capacity for a special spider that was specially designed in a project which we were contractor. Load carrying capacity of carrier weldings on stainless materials was specially evaluated.
We researched the resemblance between deformation of holder (spider) – which was designed for one of our project that has very big glasses – under the actual loads and results in computer calculations.
We used tension rods in order to carry the loads over a hanging system facade. These tension rods were transferring the loads over beams by means of pipe sections. The pin part which was designed in this work put into final form after quantify stresses on welding and deformation of pipe.
In one of our project, significantly big loads were supposed to be transferred through bonding the glass columns and beams each other and we want to do it without using bolt. In order to make certain of computer analysis, behavior of 1:1 sized samples were observed under the loads which were expected in reality.
We did a series of experiments to determine the load carrying capacity of standard production pins that were developed in to use on the tension rods whose diameter were between 8-36 mm. We can easily certify that how much load can our designs -which were produced from AISI 304 and AISI 316 quality stainless material- carry.
A series of experiments were done to find the load carrying capacity of these materials which are specially used at the corner point of panel facades and determine things to do for increase adhesion quality.
Although screws are essential connectors for façade sector, there are very few research about them. We sought the answers of questions below via our studies in laboratory and computer environment:
• How does diameter of screws' affect in tensile and shear strength
• How does type of combined material affect in load carrying capacity
• How does thickness of combined material affect in load carrying capacity
Cables are used as carrier in construction sector for a long time. However, in recent years we have seen very aesthetic facades that are raised by only cables. We have started some studies in order to reach wider knowledge than our existing knowledge which we got from books and see the reflections of our data in reality. Our experimental studies about cable systems are resuming.
