[關(guān)鍵詞] 高層建筑結(jié)構(gòu) 風(fēng)荷載位移 可靠性Based on the Unified Stanclard of Builcling Structure Design( GBJ68-84), the probabilistic distribution and statistic parameters of the structural peak displacement are obtained by two practical calculation model. According to the structural peak displacement limits set by the Regulations of Reinforced Concrete High Structure's Design and Construction(JGJ3-91), the displacement control invalid probability and the reliability target of tall building structure under the annual maximum wind distribution in the Uni fied Standard of Building Structure Deisign are reduced. A new reliability analysis method of tall building structure displacement control design and analysis is brought out.
