［摘要］日照海洋公园为国际首个将创新型海洋馆与花鸟园等多业态完美融合的海洋公园，结构形式为混凝土框架和钢框架组成的混合框架结构。该工程具有大跨度钢结构、大悬挑混凝土结构、楼板开大洞、楼板不连续等不规则类型；设计需解决海洋氯化物环境混凝土结构抗腐蚀，近海环境钢结构防腐等问题；主体结构与幕墙设计通过参数化来实现建筑复杂立面的需求。设计中较好地解决了上述结构设计难题，实现了结构与建筑的完美结合。

Abstract:Rizhao Ocean Park is the first marine park in the world to integrate the innovative aquarium with the flower and bird garden.  The mixed frame structure is composed of concrete frame and steel frame. The project has the following irregular types: large-span steel structures, large cantilevered concrete structures, large floor slab openings, and discontinuous floor slabs. The design needs to solve the problem of anti-corrosion of concrete structure in marine chloride environment and anti-corrosion of steel structure in offshore environment. The main structure and curtain wall design were parameterized to meet the needs of complex facades. In the design, the above structural design problems were solved, and the perfect combination of structure and architecture was realized.

Keywords:mixed frame structure; large span and large cantilever; slab discontinuity; concrete corrosion resistance; steel structure corrosion protection curtain wall
