ProShake 是功能強大的用戶友好型電腦程式，用於一維等效線性地震反應分析。ProShake完全由零開始編寫，具有眾多功能，可高效，有效地進行數據輸入，分析，查看和記錄結果，包括內置的模數降低和阻尼模型，土壤剖面和輸入運動參數的圖形顯示，寬範圍的圖形顯示各種輸出參數以及地震的動畫。

ProShake is organized into three "managers" - an Input Manager, a Solution Manager, and an Output Manager. The Input Manager allows entry of soil profile and input motion data. The Solution Manager performs iterative equivalent linear analyses while tracking the process of convergence toward strain-compatible soil properties. The Output Manager allows easy plotting of results in the form of time histories, response spectra, parameter profiles, and animations. A series of other parameters can also be computed.

ProShake also includes useful Report feature, as a file in Microsoft® Word® format, that automatically records the conditions of each analysis in tabular form. All ProShake plots can be copied to the Report and saved for subsequent editing in Word.

ProShake has been shown to produce results virtually identical to those produced by SHAKE91 and closed form solutions - but the process of entering data, running the analysis, and plotting the results is approximately 50 times faster with ProShake!
