SeismoArtif 2018.4.1 地震波模擬軟件
SeismoArtif是一款精巧的用於人工Accelerograms生成的地震軟件,能夠使用不同的計算方法和不同的假設生成與特定目標響應譜匹配的人工地震加速度圖。值得注意的是,建議使用真實的加速度圖和頻譜匹配技術以及記錄選擇工具來推導用於結構非線性動態分析的記錄套件。

SeismoArtif is an application capable of generating artificial earthquake accelerograms matched to a specific target response spectrum using different calculation methods and varied assumptions. It is noted that the use of real accelerograms and spectrum matching techniques (see SeismoMatch), together with records selection tools, tends to be recommended for the derivation of suites of records for use in nonlinear dynamic analysis of structures. However, in those cases where access to real accelerograms is, for whatever reason, challenging or inappropriate, then a tool such as SeismoArtif will be of pertinence and usefulness.

Generation of suites of accelerograms for nonlinear dynamic analysis of new or existing structures
Capability of reading earthquake accelerograms and spectra saved in different text file formats
The loaded collection of ground motion records and spectra is then used in the simulation phase for the definition of the target spectrum or envelope shapes

Currently, the target spectrum can be created by following rules from a selection of more than 25 National Building Codes including Eurocode 8 rules, ASCE 41-17 and various Regulations worldwide, by computing the spectrum of a specific accelerogram or by simply loading a user-defined spectrum. With both the target spectrum and the envelope type defined, an artificial accelerogram is generated and a comparison between its response spectrum and the target spectrum is given including the mean spectrum error in percentage, coefficient of variation, and PGA of the accelerogram.
