Seismic Performance Assessment of Low-rise RC Buildings: Part I

Seismic Performance Assessment of Low-rise RC Buildings: Part I

Damage indices aim to provide a means of quantifying numerically the damage in concrete structures sustained under earthquake loading. The development and application of damage indices has, until now, concentrated almost exclusively on flexural modes of failure, thus there is a clear need to investigate the ability of the indices to represent shear damage. This study, first, has chosen and shifted out a lot of experimental results from five reinforced concrete columns including numerical data and images. These existing experimental results constructed by NCREE could be interpreted by specific representative damage indices, followed by a discussion of the damage measures relating structural seismic responses. From the comparison between experimental images and damage states expressed by specific damage indices in all experimental process, qualitative and quantitative descriptions of seismic performance could be constructed for different seismic design hazard levels and the corresponding results could be a good reference for next generation performance-based seismic design provision.
