SeismoMatch 是一種能夠調(diào)整地震加速度圖以匹配特定目標(biāo)響應(yīng)譜的應(yīng)用程序，使用 Abrahamson [1992] 和 Hancock 等人提出的小波算法。[2006] 或 Al Atik 和 Abrahamson [2010] 提出的算法。加載一些加速度圖并定義目標(biāo)響應(yīng)譜后，用戶(hù)只需要定義譜匹配算法，調(diào)整譜匹配周期范圍，設(shè)置所需的容差即可執(zhí)行譜匹配。
SeismoMatch還有一個(gè)模塊，用戶(hù)可以在該模塊中組合很多匹配的加速度圖，疑惑的組合的平均匹配頻譜，以滿(mǎn)足用戶(hù)關(guān)于平均失配的要求。
特點(diǎn)：
同時(shí)匹配多個(gè)加速度圖，然后創(chuàng)建一個(gè)平均匹配頻譜，其很大失配符合預(yù)定義的容差。
可以將此軟件與記錄選擇工具和記錄適當(dāng)新驗(yàn)證算法結(jié)合使用，以定義足夠的記錄套件，用于新結(jié)構(gòu)或有結(jié)構(gòu)的非線性動(dòng)態(tài)分析。
能夠讀取以每行單位或多值格式定義的單個(gè)加速圖（強(qiáng)運(yùn)動(dòng)數(shù)據(jù)庫(kù)使用的兩種流行格式）或同時(shí)讀取多個(gè)加速度圖（如果它們?cè)趩涡卸x）每行格式的值）。
通過(guò)從超過(guò)25個(gè)地區(qū)建筑規(guī)范（包括歐洲規(guī)范 8 規(guī)則、ASCE 41-13 和各種法規(guī)）中選擇的規(guī)則、通過(guò)計(jì)算特定加速度圖的頻譜或通過(guò)簡(jiǎn)單地加載用戶(hù)定義的頻譜來(lái)創(chuàng)建目標(biāo)頻譜。
然后為匹配的加速度圖計(jì)算以下強(qiáng)運(yùn)動(dòng)參數(shù)：
彈性響應(yīng)譜和偽譜
過(guò)阻尼和恒延性非彈性響應(yīng)譜
加速度、速度和位移的均方根 (RMS)
Arias (Ia) 和特征 (Ic) 強(qiáng)度
累積速度 (CAV) 和比能量密度 (SED)
加速度 (ASI) 和速度 (VSI) 譜強(qiáng)度
Housner強(qiáng)度
持續(xù)加速度 (SMA) 和速度 (SMV)
有效的設(shè)計(jì)加速 (EDA)
主要時(shí)期（Tp）
持續(xù)時(shí)間長(zhǎng)
此外，SeismoMatch 還具有一個(gè)模塊，用戶(hù)可以在該模塊中組合匹配的加速度圖，以獲得滿(mǎn)足用戶(hù)關(guān)于平均失配要求的組合平均頻譜。
由于與 Windows 環(huán)境集成，SeismoMatch 允許將數(shù)字和圖形結(jié)果復(fù)制到 Windows 應(yīng)用程序（例如 MS Excel、MS Word 等），并指出繪圖特征可以從內(nèi)部自定義程序本身。
【英文介紹】
features :
Simultaneous matching of a number of accelerograms, and then creation of a mean matched spectrum whose maximum misfit respects a pre-defined tolerance.
Possibility of using this software in combination with records selection tools and records appropriateness verification algorithms to define adequate suites of records for nonlinear dynamic analysis of new or existing structures.
Capability of reading single accelerograms defined in both single- or multiple-values per line formats (the two most popular formats used by strong-motion databases) or of reading a number of accelerograms at the same time (if they are defined in the single-value per line format).
Creation of the target spectrum 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.
The following strong-motion parameters are then computed for the matched accelerograms:
Elastic response spectra and pseudo-spectra
Overdamped and constant-ductility inelastic response spectra
Root-mean-square (RMS) of acceleration, velocity and displacement
Arias (Ia) and characteristic (Ic) intensities
Cumulative absolute velocity (CAV) and specific energy density (SED)
Acceleration (ASI) and velocity (VSI) spectrum intensity
Housner intensity
Sustained maximum acceleration (SMA) and velocity (SMV)
Effective design acceleration (EDA)
Predominant period (Tp)
Significant duration
In addition, SeismoMatch also features a module in which a user can combine many matched accelerograms in order to obtain a combined mean spectrum that fulfils the user’s requirements regarding maximum and mean misfit.
Finally, and due to its full integration with the Windows environment, SeismoMatch allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
