摘要

Several modifications on classical Split Hopkinson Pressure Bar apparatus were implemented in order to improve the capability of systems for testing on high-strength materials. According to the theory of one-dimensional stress wave, the modification method on data handling was given. The dynamic mechanical properties of Al_2O_3 ceramics were investigated using the improved SHPB technique. It is shown that ceramics is a nonlinear elastic-brittle material. This material is sensitive to strain-rate at higher strain-rate. The dynamic modulus of elasticity and dynamic compressive strength of ceramics increase with increase in strain rate. A dynamic constitutive equation is obtained by fitting the test data.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
