Raw data of the cyclic tests on the cylindrical specimens
Birkner, Dennis
This dataset contains the raw data of the cyclic tests on concrete cylinders to determine the number of cycles to failure and the stiffness develpment of the different batches. Two concrete mixes were investigated (C30 and C80). The batch is referenced by a roman number (I to VI). The specimens were loaded with a sinusoidal load, oscillating between a relative minimum and a maximum load level. The minimum load level is 5% of the average compressive strength of the respective comcrete batch and the maximum load level either 65% or 75%, which can be found in the file name. Some specimens were subjected to a two stage loading, which is indicated by '7565' for high-low loading or '6575' for low-high loading respectively. The specimens were loaded until failure. If a maximum number of cycles of 2 million was reached, they were stopped as well and counted as run-outs.
Following channels are used in each file: Zeit (Standardmessrate) [time (standard measuring rate)] in s, Zeit (langsame Messrate) [time (slow measuring rate)] in s, Kraft [force] in kN, Maschinenweg [machine displacement] in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 0° in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 120° in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 240° in mm, Lufttemperatur [air temperature, related to the slow measuring rate] in °C, Temperatur Mitte [temperature at middle height of the specimen] in °C, Lastwechsel [number of cycles], Laser gemittelt [average of the three laser sensors] in mm

Raw data of the creep tests on cylindrical specimens
Birkner, Dennis; Marx, Steffen
This dataset contains the raw data of the creep tests on the concrete cylinder specimens. Four batches (batch 1 and 2 of concrete C80 and batch 3 and 4 on concrete C30) were tested. Three specimens were placed on top of each other in each test and loaded with the same load. The specimens are referenced with letters O (top), M (middle) and U (bottom). Following measuring channels are used in each file:
- Zeit (time) in s
- Umgebungstemperatur (ambient temperature) in °C
- Luftfeuchtigkeit (relative humidity) in %
- Kraft (force) in kN
- Verformung bei Umfang (displacement at circumference) 0° in mm
- Verformung bei Umfang (displacement at circumference) 120° in mm
- Verformung bei Umfang (displacement at circumference) 240° in mm
- Mittelweg der drei Verformungen (average value of the three displacements) in mm

Raw data of the cylinder tests for determining compressive strength and modulus of elasticity
Birkner, Dennis
This dataset contains the raw data of the tests on concrete cylinders to determine the compressive strength and the modulus of elasticity of the different batches. Two concrete mixes were investigated (C30 and C80). The batch is referenced by a roman number (I to VI). Three cylinder specimens were tested from each batch. The first was loaded with continously increasing force until failure. The ultimate load was used to determine the load levels of the tests for the modulus of elasticity according to DIN EN 12390-13, method B, for the tests on the other two specimens. After carrying out these two tests, both specimens were also loaded with increasing force until failure. Following channels are used in each file:
Zeit (Standardmessrate) [time (standard measuring rate)] in s, Zeit (langsame Messrate) [time (slow measuring rate)] in s, Kraft [force] in kN, Maschinenweg [machine displacement] in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 0° in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 120° in mm, Laser bei Umfang [displacement measured by laser sensor at circumference] 240° in mm, Lufttemperatur [relative humidity, related to the slow measuring rate] in °C, DD1_1 und DD1_2 (LVDT, placed at middle specimen height at 0° and 180°, measuring length 150 mm) in mm
