The data are associated with the book chapter “Investigation of Damage in (Ultra) High Performance Concrete under Different Moisture and Cyclic Load Conditions” (DFG Priority Programme SPP2020). Cylindrical specimens (75 mm length, 30 mm diameter) were tested over a frequency range of 0.1-1000 Hz. Each dataset ("Amplitude_sweep_bin.tar", "Frequency_sweep_bin.tar") contains MATLAB binary files with recorded signals, including axial and lateral strain, actuator displacement, piezoelectric force, UTM load cell force, input voltage, and temperature. In addition, "Final_Results.tar" contains post-processed results organized into three folders( "Amplitude_Sweep_Results", "Frequency_Sweep_Results", and "Stiffness_reduction_Results"), each including text files and corresponding PDF plots. The experimental setup is based on a static preload combined with a superimposed harmonic excitation. A universal testing machine (Schenk-Trebel RM 100) applies the static preload via a metallic stamp, while a piezoelectric actuator driven by amplified sinusoidal voltage signals (0-10 V) generates small oscillatory displacements (up to 40 μm), enabling high-resolution dynamic loading. Force measurement is performed using two complementary approaches: (i) a piezoelectric force sensor for high-frequency measurements and (ii) a calibrated aluminum reference sample in combination with the UTM load cell for low-frequency calibration (≤ 0.1 Hz), where the load cell is accurate. The aluminum specimen acts as a transfer standard, allowing the relationship between strain and force to be established under quasi-static conditions. Temperature is monitored using a PT-1000 sensor, and all signals are recorded using a high-speed data acquisition system (HBM-HBK GEN2tB and GN1640B). Tests were conducted at room temperature (21-23 °C) under preload levels of 2.7 MPa and 10 MPa. The calibration is required due to the limited frequency response of the UTM load cell. At low frequencies, force is directly measured and correlated with the strain of the aluminum reference sample. Using Hooke’s law, the Young’s modulus of aluminum (defined as the ratio between stress and strain in the linear elastic regime) is used to convert measured strain into stress and thus force. This calibrated force-strain relationship is then applied to high-frequency measurements, where direct load cell readings are unreliable. In contrast, Poisson’s ratio is obtained directly from locally measured longitudinal and transverse strains as their ratio, and therefore does not require calibration. Post-processing is performed using the MATLAB script “Main_Post_Processing_code.m” (provided in “Post_Processing_Code_Extract_Results.tar”). Young’s modulus of the UHPC specimen is calculated as the ratio between calibrated stress, derived from the aluminum-based force calibration (ASbottom-AluB L stress_cal) and the measured longitudinal strain (SampleDMS_L). For Poisson’s ratio, the transverse strain (SampleDMS_Q) and longitudinal strain (SampleDMS_L) are directly evaluated. The results are automatically exported as text files.
