【摘要】 新型建筑结构将调频质量阻尼器控制原理应用于自身建设当中,具有非常突出的抗震效力。文中综合研究了脉动风作用时影响新型结构动态特性的两个重要参数——子结构质量和附加柱刚度,分析了不同子结构质量时附加柱刚度变化对巨、子结构动力响应的影响,归纳了子结构质量影响新型建筑结构动力性能的一般规律。研究表明,新型结构比传统巨型框架结构具有更好的抗风振能力,而且其抗振性能会随子结构质量及附加柱刚度的变化而发生改变。更多还原

【Abstract】 New building structure , which applies the controlling theory of tuned mass damper to self-configuration of building, has strong effectiveness of vibration-resistance , and has gained more attention in recent years. In this paper, two important structural parameters that affect dynamical characteristic of this building are researched together. Effect of additive column on dynamical response of mega- and sub-structure under different sub-structural mass is analyzed. General rules that the mass of sub-structure affect dynamical characteristic of this new building are concluded. Researching results indicate that compared to traditional mega-sub frame, this new building structure has more ascendant dynamical capability, and that its effectiveness of vibration-resistance has close relation with sub-structural mass and stiffness of additional column.更多还原
