Abstract: Shanxi Province Library is one of out of codes high-rise buildings. This paper presents some measures and structural calculations for this complex building. Then buckling brace is applied in order to improve the seismic performance and energy dissipation mechanism, which is detailed for its advantages in followed chapters. At last elastic-plastic time-history analysis was operated, which acquired the plastic developing process and the collapse of the way through the whole process of analysis.
Keywords: out of codes high-rise building; buckling brace; elastic-plastic time-history analysis
