简介
Walk‐up flats are typically supported by slender columns on the ground floor forming a soft storey. The column slenderness ratio can be in the order of 6–9. Some of these buildings are right next to busy streets and hence continuously exposed to the potential hazard of a vehicle impacting on a column in an accident. In the early part of this study, the ultimate energy absorption capacity of a reinforced concrete column is compared to the kinetic energy embodied in the moving vehicle. The energy‐absorption capacity is calculated from the force‐displacement curve of the column as determined from a nonlinear static (push‐over) analysis. The ultimate displacement of the column is defined at the point when the column fails to continue carrying the full gravitational loading. Results obtained from the nonlinear static analysis have been evaluated by computer simulations of the dynamic behavior of the column following …
