Abstract:
A five story reinforced concrete building which collapsed during the Mindanao, Philippines Earthquake of August 1976 is studied. The building experienced a twisting motion dur-ing its collapse. The damages to the building are described, and design calculations which consider the twisting are performed. The calculation results show that a number of columns were understrength but that other factors such as reinforcement detailing and material quality influenced the seismic performance of the building.
