[书]PERFORM-3D原理与实例 – 第 13 章 – 变形监测单元
[Book] PERFORM-3D Theory and Tutorials – Chapter 13 – Gap-Hook Element
- 章节内容简介 [ Chapter Content Abstract ]
作为一款结构抗震性能评估软件,PERFORM-3D可以计算和输出各种非线性单元的变形需求-能力比。但对于某些单元,可能存在应变集中,以至于求出的需求/能力比非常大,如果是局部应变集中,以这些单元的需求-能力比作为性能评估的依据就会过于保守。为此,PERFORM-3D提供了一类特殊单元,即变形监测单元(Deformation gage element)[1, 2],该类单元不参与有限元的计算,仅用于监测多个单元的平均变形。变形监测单元具有变形能力属性,使得变形监测单元可以像其他单元一样,通过在建模阶段的【Limit States】模块定义基于变形监测单元的变形极限状态,PERFORM-3D可计算和输出基于变形监测单元的平均变形计算的需求-能力比。
PERFORM-3D总共提供了四种变形监测单元,包括轴向应变监测(Axial Strain Gage)单元,梁转角监测(Rotation Gage Beam Type)单元,墙转角监测(Rotation Gage Wall Type)单元,剪切应变监测(Shear Strain Gage)单元。每一种变形监测单元均由相应的变形监测组件组成,所有变形监测组件均在建模阶段的【Component properties】-【Elastic】模块下定义。
