报告摘要：

The columns are widely used in different structures (e.g., bridges, buildings, and electric poles) to mainly support the vertical loads. These structural elements are exposed to the potential hazard of land or marine vehicle collisions which can produce strong lateral loading, generate significant damage and cause a large general risk. Recently, the vehicle collision hazard has increased, due to the growth of road construction and urban traffic, especially in developing countries. In this context, the College of Civil Engineering of Nanjing Tech University is a leading research center in the experimental and numerical analysis of impact engineering. The college is provided with two important experimental labs (a bi-directional large-scale drop-weight testing machine and large-scale Split-Hopkinson Bar) and one computational center. This talk will report a summary of the results obtained at material level using the Split-Hopkinson Bar on concrete and CFRP wrapped specimens and of the last results obtained on Reinforced Concrete columns and on Concrete Filled tubes using the bi-directional large-scale drop-weight testing machine. Moreover, the effectiveness of seismic CFRP wrapping to reduce impact is also analyzed. Finally, some preliminary results obtained on post-tensioned beams are shown.
