Robustness of reinforced concrete columns
Enhanced design rules on compression members using high-strength and ultra-high performance concretes
The robust design of supporting structures is the basis for every structural design. Damages caused by unplanned loads must be limited to a reasonable extent in order to prevent abrupt failure or progressive collapse. While abrupt tensile failure occurring at structural members subjected to bending loads is prevented by complying with the minimum reinforcement for ensuring a ductile behavior of the component, a robust component failure occurring at structural members subjected to compression loads cannot be guaranteed by the current structural design requirements in all cases (Fig.).
