CSI PERFORM-3D介紹
1、基於位移的設計
傳統的抗震設計是基於強度的，使用線性彈性分析。
既然強震下允許出現非彈性行為，這就不是完全合理的。
基於強度的設計只是間接地考慮了非彈性行為。
基於位移(或基於變形)的設計直接考慮了非彈性行為，使用非線性非彈性分析。
基於位移的設計認識到在強震中非彈性變形(或延性)比強度更重要。
PERFORM-3D提供基於位移的設計方法。
2、實現ASCE 41
在ASCE 41(既有建築抗震修復)中規定使用非彈性分析來進行基於位移的設計。
ASCE 41 應用與既有建築的修復，但這種方法可以應用於新建築的設計。
PERFORM-3D實現了ASCE 41的方法。
然而， PERFORM-3D是一個實現基於位移設計的通用工具，並不侷限於ASCE 41。
3、能力設計
結構在地震中的響應，無論是彈性的還是非彈性的，都是高度非確定性的。
能力設計是一種合理方法來改進結構在強震作用下的響應，審慎控制結構的行為。
能力設計控制結構的非彈性行為，允許非彈性行為出現在設計師選定的部位，在這些部位，結構構件被設計為延性，結構的其餘部分基本保持彈性，可以是很小的延性。
這種控制行為的方法提高了可靠度，減少了破壞的數量，並能降低建造成本。
PERFORM-3D允許用戶使用強度設計原則。
Computers and Structures, Inc. (CSI), leader in software tools for structural and earthquake engineering, has released 7.0.0 version of PERFORM-3D is a structural-engineering software useful for the performance assessment of structural systems.
Changes from version 6.0.0 (Released 2016-12-20):
Enhancements Implemented
207340 An enhancement has been made to allow running up to eight analysis series in parallel. The number of parallel analyses run will be reduced to physical CPU s present on the machine if less than eight in order to prevent competition that would be less efficient.
207334 The version number has been changed to v 7.0.0 for a new major release
Incidents Resolved
97373 Default locations listed in Sections 15.1.2 and 16.2.1 of the User Guide documentation have been updated to be consistent with Sections 2.2 and 2.3 of the User Guide documentation.
99896 An incident was resolved where Perform 3D v6.0.0 was unable to read in text files
100558 in the Import Structure Data task (Build Phase). This issue affected Perform 3D v6.0.0 only.
100507 An incident was resolved where the analysis could not be run on a machine that
202697 had more than 16 physical cores. When this occurred, no results were available.
202917 Where the analysis was able to run, no results were affected by this issue.
About CSI PERFORM-3D. Traditionally, earthquake-resistant design has been strength-based, using linear elastic analysis. Since inelastic behavior is usually allowed for strong earthquakes, this is not entirely rational. Strength-based design considers inelastic behavior only implicitly. Displacement-based (or deformation-based) design considers inelastic behavior explicitly, using nonlinear inelastic analysis. Displacement-based design recognizes that in a strong earthquake, inelastic deformation (or ductility) can be more important than strength. PERFORM-3D allows you to use displacement-based design.
PERFORM-3D has powerful capabilities for inelastic analysis, but it is not intended for general purpose nonlinear analysis. If you have no idea how your structure will behave when it becomes inelastic in a strong earthquake, PERFORM-3D can probably help you to identify the weak points, and hence can guide you in improving the design. However, PERFORM-3D is not intended for “design by analysis”, where the engineer expects the analysis to determine exactly how a structure will behave. PERFORM-3D is a powerful tool for implementing displacement-based design and capacity design. It will help you to produce better designs, but it will not do the engineering for you.
About Computers and Structures, Inc. Founded in 1975, Computers and Structures, Inc. (CSI) is recognized globally as the pioneering leader in software tools for structural and earthquake engineering. Software from CSI is used by thousands of engineering firms in over 160 countries for the design of major projects, including the Taipei 101 Tower in Taiwan, One World Trade Center in New York, the 2008 Olympics Birds Nest Stadium in Beijing and the cable-stayed Centenario Bridge over the Panama Canal. CSI's software is backed by more than three decades of research and development, making it the trusted choice of sophisticated design professionals everywhere!
