STRUCTURES LABORATORY
The Structures Laboratory is a 300 m2 closed area which is mainly used for the researches of graduate students and also used by undergraduate students for the laboratory courses and also suitable for the research projects and projects taken in revolving funds. Within the Structures Laboratory there is a Loading Frame and test equipment for the testing of structural elements, a mobile crane to transport large-scale samples, and a large stock area for storing test samples before or after testing.
Structures Laboratory
Structures Laboratory has a vertical load loading frame of 30 tons capacity. Bending tests and torsion tests can be performed on 1/1 scale reinforced concrete, steel and wooden structural elements with manually controlled hydraulic load actuators placed on this frame. A total of 6 hydraulic load actuators with 10 tons, 30 tons and 60 tons capacities and different stroke capacities are used in the experiments. In addition, the electrically controlled hydraulic pump capable of producing 700 bar pressure is used to loading at constant speed.
Additionally, digital load cells with various capacities, potentiometers and displacement meters capable of measuring different lengths, as well as unit deformation gauges (strain gauges) that can be affixed to different materials are used in the structures laboratory.
During the experiment, high speed data acquisition systems are used which digitally record the values obtained from the measuring instruments and transfer them to the computer environment.
