【摘要】：软钢阻尼器作为优异的消能减震元件,在现代结构的抗震设计中,具有越来越广泛的应用。基于软钢阻尼器的应用和研究现状,根据等值线性分析方法,探讨软钢阻尼器的工程设计方法,并将该方法应用于某商业广场项目塔楼结构的减震设计分析。该塔楼高度为118.9m,框架-核心筒结构,临近地铁,在结构设计分析中,需在保证结构具有足够的承载力和良好的经济性能的前提下,对构件截面进行优化,使结构自重减轻,减少结构沉降对地铁隧道产生的不利影响。通过布置软钢阻尼器并对结构抗震性能进行对比分析,研究结果表明:布置阻尼器的结构,构件截面得到明显优化,结构总重降低,满足设计要求,结构的承载力性能与未布置软钢阻尼,未进行构件截面优化的结构保持在相同水准,同时,阻尼器的布置使得结构软钢阻尼器可延迟主体结构进入弹塑性阶段,提高结构在罕遇地震下的抗震性能。
[Abstract]:As an excellent energy dissipation element, mild steel dampers are more and more widely used in seismic design of modern structures. Based on the application and research status of mild steel damper, according to the isoline analysis method, the engineering design method of soft steel damper is discussed, and the method is applied to the design and analysis of the tower structure of a commercial square project. The height of the tower is 118.9 m, the frame-core tube structure is adjacent to the subway. In the structural design and analysis, it is necessary to optimize the section of the member under the premise of ensuring the structure has sufficient bearing capacity and good economic performance, so as to reduce the weight of the structure. Reducing the adverse effect of structural settlement on subway tunnel. Through the arrangement of mild steel dampers and the comparative analysis of seismic performance of structures, the results show that the section of components is obviously optimized and the total weight of structures is reduced to meet the design requirements. The bearing capacity performance of the structure is at the same level as that of the structure without soft steel damping, and the structure without section optimization is kept at the same level. At the same time, the arrangement of the damper can delay the main structure into the elastoplastic stage. Improve the seismic performance of the structure under rare earthquake.
