INTRODUCTION OF THE LABORATORY
The Structural Engineering Laboratory is located in a 220m2 place with top running overhead crane (capacity: 10 tons) and an external industrial gate. The main profil of the laboratory is the study of construction and transport structures. In the laboratory there are avalible an universal testing machine (load capacity: 400 kN) and a bending machine (load capacity of 150 kN) for testing smaller structures and models. Larger structures are tested using load frames with a capacity of 1000 kN. It is possible to measure elements up to 15 m long and 2 m high in the main loading zone. The measuring range of the load cells is 200 kg - 2000 kN, the movements can be recorded with displacement sensors with the accuracy of 0.001 mm, the measuring range is up to 400 mm. For dynamic measurements, a 15 kN and a 300 kN dynamic testing machines, as well as impulse hammers are available, The dynamic tests are performed with single- and multi-axis accelerometers. The laboratory's measurement technology and measurement preparation background (machinery, measuring instruments, softwares) is undergoing continuous development in order to be able to meet the emerging needs. Thanks to the modular and mobile machinery of the laboratory, it is also possible to measure built-in structures.
