双向张拉索-混凝土结构的抗震分析
|
摘要
传统的钢筋混凝土梁结构和钢结构,都有其相应的局限性,随着研究的不断深入,为了实现大跨度,满足日益增长的功能要求,提出了一种新型结构体系"索-混凝土组合梁结构体系"。该体系是通过降低混凝土梁高,在梁下方增加预应力拉索的方法来实现的。这种结构应用于公共建筑、民用建筑和工业建筑中,既节省了空间,又提高了承载力,有广阔的应用前景。对双向张拉索-混凝土结构进行了抗震性能分析。得出如下结论:运用大型有限元分析软件ANSYS对双向张拉索-混凝土组合结构进行了地震作用下的响应分析。选用天津波、美国EL-Centro波二种波作对比,应力反应跨中较大;索作为一种柔性材料,变形较大,反应剧烈,不稳定。
With the development of economy and society,people demand more and more space on building so that large span structure has been developed rapidly and applied widely.The traditional reinforced concrete beam and steel structure have their corresponding limitations.With the deepening of the study,some people put forward a new structure "the cable-concrete beam system" with lower height of reinforced concrete beam and cable under the cable-concrete structure,in order to achieve larger span and meet the growing functional requirements.This structure is used in public buildings,civil construction and industrial construction,which saves space and increases the load bearing ability,it has broad application prospects.This dissertation studies thestatic analysis,natural vibration characteristics,and seismic characteristics of two-way cable-concrete structure.The conclusions are as follows: By using ANSYS which is a large finite element analysis software,the response analysis of the structure under earthquake action has been studied.Compared with Tianjin wave,EL-Centro wave of Amercian,stress reaction is greater at mid-span;as a kind of flexible material,the cable has a larger deformation,strong reaction and instability.
