SeismoArtif - 地震波人工生成软件

生成与特定目标响应谱匹配的人工地震加速度图

SeismoArtif 是一个应用程序，能够使用不同的计算方法和不同的假设生成与特定目标响应谱相匹配的人工地震加速度图。值得注意的是，使用真实的加速度图和频谱匹配技术（参见SeismoMatch）以及记录选择工具，往往被推荐用于推导用于结构非线性动态分析的记录套件。然而，在那些访问真实加速度图的情况下，无论出于何种原因，具有挑战性或不合适，那么像 SeismoArtif 这样的工具将具有针对性和实用性。

目前，目标频谱可以通过从超过25个地区建筑规范（包括 Eurocode 8 规则、ASCE 41-17 和各种法规）中选择的规则、通过计算特定加速度图的频谱或简单地加载用户来创建 -定义的频谱。在定义目标谱和包络类型后，生成人工加速度图，并给出其响应谱与目标谱之间的比较，包括加速度图的平均谱误差百分比、变异系数和 PGA。

可视化的界面。没有输入或配置文件、编程脚本或其他耗时且复杂的文本编辑要求。

• 为新结构或现有结构的非线性动态分析生成加速度图套件

• 能够读取以不同文本文件格式保存的地震加速度图和频谱

• 然后在模拟阶段使用加载的地面运动记录和频谱集合来定义目标频谱或包络形状

由于与 Windows 环境集成，SeismoArtif 允许将数字和图形结果复制到 Windows 应用程序（例如 MS Excel、MS Word 等），并指出绘图特征可以在程序本身内自定义。

【英文介绍】

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.

This software can be used to generate suites of accelerograms for nonlinear dynamic analysis of new or existing structures. The program is capable of reading accelerograms and spectra saved in different text file formats. This collection of ground motion records and spectra is then used in the simulation phase for the definition of 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 41-13 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 error in percentage, coefficient of variation, and PGA of the accelerogram.

Finally, due to its full integration with the Windows environment, SeismoArtif allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the characteristics of the plots can be fully customised from within the program itself.
