Research on the development of collapse curves for reinforced concrete frame building under the influence of water depth and flow velocity in flood-prone areas of Vietnam

Abstract

This study develops a collapse curve model for reinforced concrete frame buildings based on water depth and flow velocity to determine their resilience to flood impacts. The research establishes a theoretical foundation and analytical process for developing the collapse curve by Vietnamese building standards, considering hydrostatic and hydrodynamic pressures, wind loads and the self - weight of the structure. The results reveal significant differences in the collapse potential of two - story reinforced concrete frame buildings in cases of rapid flood rise (i.e., dam failures) and slow flood rise (like river floods). This study contributes to the scientific basis for developing collapse curves in Vietnam, enabling broader estimates of flood damage and risk for buildings, thus enhancing disaster response capabilities and community protection.
