結構系統之數值模擬，所使用之結構物數值模型必須要能夠詳細地囊括結構物於不同尺度之行為，此類之計算工作必須要有大量的計算資源以及高速運算的技術來配合，近年來網際網路已革命性地改變了電腦的運作方式，格網運算之網路即電腦之概念被認為是提升現有電腦計算能力的最可能方向，網際網路連結了無數的電腦，理論上可產生無可限量的計算能力，然而遠距的資料交換是格網計算的一大瓶頸。
本研究嘗試使用多層次之叢集架構，將多個地理上遠距的電腦叢集，經由網際網路相連整合而成的格網式計算環境，並配合整合多尺度數值模型之階層式計算環境，以整合多個構件詳細數值模型之分析工作來模擬整體結構物於各種不同尺度之行為。為解決網際網路資料溝通效率低之障礙，本研究採用主從式來設計系統架構，即是用戶端所使用之某個簡化構件模型，其在伺服端必須有一個對應的詳細構件模型，以其於遠端之模擬結果提供近端簡化構件模型之詳細行為反應。依據所提出之分析模擬方法，本系統是基於格網運算的架構，整合多個地理上遠距的電腦叢集，配合主從式的多尺度值模型之階層式模擬架構來對結構物系統做數值模擬，同時並使用系統測試實例來驗證本系統之可行性。

This study has presented a framework for a Grid-based structural simulation by integrating a Grid-based cluster-to-cluster distributed computing environment and a multi-level hierarchical method of modeling and simulation. The purpose of this study is to utilize the idle and available computational resources which are geographically distributed on the Internet for providing the computing power needed for processing structural simulations. Two levels of parallel processing are involved in this framework: multiple local distributed computing environments connected by the Internet to form a Grid-based cluster-to-cluster distributed computing environment. To utilize such a computing environment for a realistic simulation, the simulation task of a structural system has been separated into a simulation of a simplified global model in association with several detailed component models using various scales. These related multi-scale simulation tasks are distributed amongst clusters and connected to form a multi-level hierarchy. The Grid computing technology is used to coordinate geographically distributed simulation tasks. This study also presents the development of a software framework that can support the multi-level hierarchical simulation approach, in a Grid-based cluster-to-cluster distributed computing environment. The architectural design of the program also allows the integration of several multi-scale models to be clients and servers under a single platform. Such integration can combine geographically distributed computing resources to produce realistic simulations of structural systems.
