Abstract：
Considering that it is a project requiring 9-magnitude aseismic fortification and that the structure of node between profile steel and beam is complex, the beam-column node of the profile steel reinforced concrete structure must be optimized. The original method was improved through proposal of optimal design thought and analysis on structural requirements and construction process. After comparison and analysis between the original and optimized construction process, the aseismic performance of the structure was improved and construction difficulty was reduced.
