Abstract EN
The dynamic characterization of concrete is fundamental to understand the material behavior in case of heavy earthquakes and dynamic events.
The implementation of material constitutive law is of capital importance for the numerical simulation of the dynamic processes as those caused by earthquakes.
Splitting tensile concrete specimens were tested at strain rates of 10−7 s−1 to 10−4 s−1 in an MTS material test machine.
Results of tensile strength versus strain rate are presented and compared with compressive strength and existing models at similar strain rates.
Dynamic increase factor versus strain rate curves for tensile strength were also evaluated and discussed.
The same tensile data are compared with strength data using a thermodynamic model.
Results of the tests show a significant strain rate sensitive behavior, exhibiting dynamic tensile strength increasing with strain rate.
In the quasistatic strain rate regime, the existing models often underestimate the experimental results.
The thermodynamic theory for the splitting tensile strength of concrete satisfactorily describes the experimental findings of strength as effect of strain rates.
