| An experimental research on high-strength concrete (HSC) frame structure reinforced with high-strength rebars is presented. The pseudo-dynamic tests were performed for 1/2 scale frame model with two floors and two bays using MTS loading system. The test is to develop the seismic behavior of the frame with high-strength concrete and pre-stressed rebars. The specimen was subjected to 11 loading cases by using three kinds of acceleration records of ground motion with the adjusted amplitude, focusing on study of change of dynamic character during earthquakes, cracking patterns, hysteretic behaviors and seismic responses in elastic and elastic-plastic stages. The experimental results show that this kind of HSC frame structure can meet the requirements of the seismic performance. The results of the test may open a new road for the application of HSC frame structure in seismic zone. |
