  • 程序介绍 ( Program Introduction)

地震反应谱是地震工程中重要的概念,我们经常需要将地震加速度时程转换为反应谱。SPECTR 是一个简单易用的反应谱计算程序。

Seismic Response Spectra is an important concept in earthquake engineering, we often need to evaluate seismic response spectrum on the basis of a given time-acceleration record. SPECTR constitutes an easy way to evaluate Seismic Response Spectra, featuring a user-friendly visual interface. It is a helpful tool for engineers. 

SPECTR具有以下特点:

(1)导入不同格式的加速度时程,一次可导入多组加速度时程

(2)可对加速度时程进行基线修正,软件提供线性和抛物线基线修正方法

(3)对加速度进行积分生成相应的位移时程序和速度时程

(4)目前支持以下几种弹性反应谱的分析:相对位移反应谱、相对速度反应谱、绝对加速度反应谱、拟速度反应谱和拟加速度反应谱

(5)支持图形式和表格形式查看时程数据、反应谱数据。表格数据支持复制操作,可方便通过快捷键将数据粘贴至Excel快速绘图。

(6)可自由选择坐标轴进行谱曲线绘制,方便谱曲线结果的对比

(7)支持批量进行加速度时程的积分和反应谱分析,并支持批量导出分析结果。方便数据的进一步后处理

SPECTR has the following features:

(1) Read accelerograms saved in in different text file formats ( beside General File Format, PEER NGA Format (.AT2), Midas .dbs / .sgs Format,  SeismoSignal (.dat) Format, YJK(盈建科) Ground Motion File Format Supported were added in SPECTR version 1.1), Read multiple sets of accelerograms at a time.

(2) Baseline correction of the accelerograms 

(3) Numerically integrates the accelerograms record to generate the corresponding ground motion speed and displacement time history 

(4) Elastic response spectra and pseudo spectra

(5) Allows for results to be copied to any windows application(e.g. MS Excel, MS Word, etc.)

(6) the Seismic Response Spectra plots can  be fully customised from within the program itself

(7) Export multiple sets of results ( displacement and velocity time history of ground motion and Seismic Response Spectra) at a time

程序的使用步骤:

(1)准备好加速度时程文件(文本格式)

(2)打开SPECTR,设置导入格式参数,将准备好的加速度时程文件导入软件

(3)软件自动对导入的加速度时程进行积分计算获得位移和速度,可选择对加速度时程序进行基线修正。如果加速修正后,反应谱会基于修正的加速度时程进行计算。

(4)设置反应谱分析参数(最大、最小周期、阻尼比等)

(5)勾选(Check)需要批量导出加速度时程结果或反应谱分析结果的文件,批量将分析结果导出到文本文件。

The overall steps are as follows.

(1) Prepare accelerograms in text format.

(2) Import accelerograms

(3) SPECTR automatically integrates the accelerograms to generate the corresponding ground motion speed and displacement time history. You can apply baseline correction to accelerograms. If the baseline correction is applied, the response spectra analysis is based on  corrected accelerograms.

(4) Set parameters for Response Spectra calculation (e.g. Maximum period, Minimum period, damping ratio, etc. )

(5) Export multiple sets of results ( displacement and velocity time history of ground motion and Seismic Response Spectra) at a time

    您好,请问spectr V1.1软件,在之后会提供下载吗?

      以后再看吧,集成到更大的软件中去,暂时不免费提供了。可以用免费版v1.0,功能基本够用了。
