Infrastructure engineering and sustainable design are among the important drivers of sustainable development. Increased industrialisation has brought to the forefront the susceptibility of concrete columns (in both buildings and bridges) to vehicle impacts. Accurate vulnerability assessments are crucial in the design process due to the possibly catastrophic nature of the failures that can occur. This chapter reports on research undertaken to investigate the impact capacity of columns of low to medium raised buildings designed according to the Australian standards. Numerical simulation techniques were used in the process and validation was done by using experimental results published in the literature. The investigation thus far has confirmed the vulnerability of typical columns in five story buildings located in urban areas to medium velocity car impacts. Hence, these columns need to be re-designed or retrofitted. In addition, accuracy of the simplified method presented in EN 1991-1-7 to quantify the impact damage was scrutinised. A simplified concept to assess the damage caused by all collision modes was introduced. The research information will be extended to generate a common database to assess the vulnerability of columns in urban areas to the new generation of vehicles.
