The development process for the seismic appraiser and strengthening of building structures in our country is reviewed. Some problems on the seismic appraiser and strengthening of building structures, such as the probability level of the objective of seismic protection for appraiser, the concept design on the seismic appraiser and strengthening, the judgement on compound seismic capability of structure and the coordination for transformation and strengthening of building structures, are investigated.
Keywords: building structure; seismic appraiser; seismic strengthening; objective of seismic protection; probability analysis; compound seismic capability
