本文包括兩部分，第一部分為研擬一套適用於平面應力構件之配筋規則，除了強度檢查方式的推導外，並以傳統細長構件中較適合以平面應力問題分析之深梁、牆、版殼為驗證資料，對所發展之平面應力配筋規則除了對相同問題能符合現行法規之設計要求外，亦將一體適用於各種形狀的平面應力構件，而不同於法規只局限某幾種形狀。亦針對各種結構模式，如細長桿件、平面應力、平面應變等做一簡介，並深論以不恰當模式分析之缺點所在，由此指出現行設計法則之缺失。除了與現行規範之設計結果比較外，亦與試驗結果加以比較，試驗之過程及觀測方法文中亦加以詳述。並自行發展簡化有限元素法模式之程式以探討混凝土開裂後應力狀態。
第二部分為發展出鋼筋混凝土平面應力元素轉換為等效軸力桿件所需之剪力元素，探討以獨立的軸力元素取代一個連續體以及相關的剪力元素問題。以四周四支軸力桿件的基礎上探討剪力元素的模擬，本文總共提出三種方法，三種方法皆有完整的推導與對應之程式，並以例題探討其模擬之精度，配合三種方法所發展的程式具有良好的繪圖能力及資料推展，因此可以極少量的控制資料做出多種問題的模擬，本文亦將程式的發展與成果以例題顯現。

This study developed a set of plane stress components applied to the reinforcement rules, apart from the inspection of the deduced intensity, but also the traditional elongated to fit more components in plane stress analysis problem of deep beams, walls, version of the shell in order to verify the information, For the development of reinforced concrete plane stress problem of the same rules except to comply with current design requirements and regulations, will be one-size-fits all shapes in the plane stress components, and different laws and regulations is confined to certain kinds of shapes.

In this paper, also for various structure models, such as slender beam, plane stress, plane strain, such as make one brief introduction, and found it on to the appropriate mode of analysis does not disadvantage the host, which pointed out that the deletion of the current design rules.

Except with the existing norms of design results, but also with one to compare the test results, test the process and methods of observation have to be detailed in the text. And one on its own development model of finite element method stress state after the concrete cracks.

Simplified elements are often used to simulate reinforced concrete members and walls. Since cracking and nonlinear material behavior makes the simulation complex and difficult, therefore a simplified model with nonlinear abilities is suitable for this kind of material. This article explores the possibilities to use independent truss elements for normal stresses and inde-pendent shear elements for shear stress. The plane stress problem is used as the example to examine the developed shear elements. Three types of shear elements are developed in this study. The derivations and corresponding programs are shown in this paper also. Three ex-amples are illustrated to compare the three shear elements. The developed programs own effi-cient data generation and good drawing capacities.
