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 bearing 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.
