Abstract: The project is about the modification and reinforcement of a two-layer frame structure. The applicable codes system and the subsequent operational life were confirmed in the design document. The parameter for calculation was adjusted based on the subsequent operational life. The modification methods were selected by the architectural demands.
Keywords: frame structure; modification and reinforcement; subsequent operationallife
