以往土木領域的工程師在從事結構分析與設計相關工作時，大多憑藉著經驗與深厚的結構知識來進行分析與設計工作，隨著時代的進步，電腦使用的普及，在現今來說，大多數的土木結構分析與設計工作都交由電腦程式來進行運算，如何讓這些結構分析與設計軟體的操作變的更加簡易以及聰明，儼然成為土木領域的程式設計師開始重視的一環。本研究的主要目的是利用物件導向技術發展一套自動化鋼筋混凝土結構分析前置處理程式AutoRC，藉由簡化介面的設計，以及提供自動化模型產生、載重分配以及斷面概算功能，幫助土木工程師能夠花很少的時問就能夠完成結構分析前置處理作業，並且不需要花費許多時間來學習軟體的操作，有效的提高工作效率，降低軟體的使用門檻。

In the past the civil engineers design and analysis a building by experiences . As the fast growth of computer technology, most design and analysis of construction are calculated by computers . So , how to make the structural analysis software easier to use becomes an important topic for programmers . The purpose of this research is using object-oriented programming technique to develop an automatic reinforced concrete structural preprocessing program ( AutoRC ) . The system has simple interface , and it can automatically perform model generation , load distribution , and section estimation . Therefore , this system can help engineers to finish the structural analysis preprocessing faster and spend less time to learn the software operation . Consequently , the work efficiency will be increased , and the system is also easy to use .
