Abstract:Based on the investigation of 275 existing public buildings in China,  the structure, bearing capacity, seismic structure, seismic bearing capacity, damage status, deformation status and durability of these buildings were identified. The present situation of the safety performance of existing public buildings with different ages, different structure types, different regions and different uses was obtained. Combining with the investigation results and the existing standards and codes for the appraisal and evaluation of the safety performance of existing public buildings, the classification methods of various performances were summarized and the classification suggestion of the safety performance of existing public buildings was put forward, providing quantitative standards for improvement of safety performance of existing public buildings.

Keywords:existing public buildings; safety performance; investigation; classification
