摘　　要：提出新型结构体系承担风载作用时存在两种方案:一是巨、子结构共同承担脉动风载,二是单纯依靠巨结构承受风载。提出在新型结构中设置附加柱的想法。分别对脉动风载下附加柱刚度对两种承载方案中巨、子结构顶层动力响应的影响进行研究。并对方案一中附加柱刚度对整体子结构的动力影响进行研究。研究表明:附加柱能够有效调节新型结构动力性能,提高新型结构体系整体抗振能力。Two wind load hearing schemes for the new building structure are firstly advanced. The idea of setting additive column in this new building structure is firstly proposed. Based on the two load-bearing schemes, the effect of the stiffness of additive column on the dynamic performances of the top mega and sub-structure subjected to pulsating wind loads is investigated. The dynamical responses of the holistic sub-structure with different stiffness of the additive column are analyzed. The research indicates that additive column can adjust the dynamic performance of this new building structure, and effectively improve its holistic vibration-resistance ability.
