| Abstract (English): |
The paper presents observed damage in reinforced concrete buildings during the 27 February 2010 Maule earthquake in Chile. Performance of concrete frame and shear wall buildings are discussed with emphasis on seismic deficiencies in design and construction practices. It is shown that the majority of structural damage in multistorey and high-rise buildings can be attributed to poor performance of slender shear walls, without confined boundary elements, suffering from crushing of concrete and buckling of vertical wall reinforcement. Use of irregular buildings, lack of seismic detailing, and the interference of nonstructural elements were commonly observed seismic deficiencies. A comparison is made between Chilean and Canadian design practices with references made to the applicable code clauses. Lessons are drawn from the observed structural performance.

| Abstract (French): |
Cet article traite des dommages observés aux bâtiments en béton armé subis lors du séisme à Maule, Chili, le 27 février 2010. Le comportement des bâtiments à ossature de béton et à murs de contreventement est abordé en faisant ressortir les manques sismiques dans la conception et les pratiques de construction. Il est montré que la majorité des dommages structuraux dans les immeubles à plusieurs étages et de grande hauteur peut être attribuée au piètre rendement des murs de contreventement élancés, sans éléments de contour frettés, qui souffre de l'écrasement du béton et du flambement de l'armature verticale des murs. L'utilisation de bâtiments non standards, le manque de détails sismiques et l'interférence d'éléments non structuraux ont été les manques sismiques les plus souvent observées. Les pratiques de conception chiliennes et canadiennes sont comparées avec des références aux normes des codes applicables. Des leçons sont tirées du comportement structural observé.
