Abstract: Hotel A in Yanlord Marina Centre Hotel, which has structural height of 190.4m and height-width-ratio of 6.3, adopts frame-core wall structural system with strengthened layers. The building has many out-of-code items including beyond B-level height requirement, vertical component discontinuity and lateral stiffness mutation. The max cantilever length of the structure is 15.9m, which belongs to complicated out-of-code structure. The safety and reasonable cost of the structure are ensured by multi-method calculation analysis, performance-based seismic design, multi defence line suspended system and appropriate design measure.
Keywords: out-of-code high-rise building; seismic performance objective; strengthened layer; frame-core wall structure; suspended structure
