| 中文摘要: |
| 高层建筑偏心支撑钢框架结构作为一种新型结构体系近年来得到迅猛的发展,在地震作用下,偏心支撑钢框架的耗能梁段率先受剪屈服,通过它的塑性变形来耗散地震能量,从而减小结构其他构件的受力,以保证整个结构的安全[1]。本文是从总耗能长度一致的情况下,分析了其对偏心支撑钢框架抗震性能的影响。本文运用有限元分析软件SAP2000,分别对四种形式(人字形、V字形、八字形、单斜杆)的偏心支撑进行分析。 |
| 英文摘要: |
| High-rise eccentrically braced steel frame structure is a new type of structural system which is developed in recent years . Under the action of the earthquake ,eccentrically braced steel frame girder to take the lead in the shear yield of energy consumption .Through its plastic deformation to dissipation of earthquake energy ,to reduce the stress of the other components of the structure to ensure the safety of the structure [1].In this paper, from the total energy consumption under the condition of same length ,analyses the influence on seismic performance of eccentrically braced steel frame. This paper uses finite element analysis software SAP2000 to analysis the four forms ,the chevron, the V, the eight-lane, the single diagonal eccentric support. |
