本文依據一階剪切變形理論，由虛功原理推得圓柱殼平衡方程式及其邊界條件的位移與合應力的關係式，並且運用加權殘值的概念引進移動最小功法求得數值解，其特點為加權函數是取其共軛的殘值，使其產生類似做功的概念。移動最小功法的近似即是利用局部的基底函數展開建立全區域連續之近似函數。
文中針對封閉圓柱殼與開放圓柱殼兩種結構型式進行分析討論，並將此數值方法以不同的佈點方式及不同的基底階數與解析解比較，以驗證此方法的可行性，並分析其誤差收斂的情形。

In this thesis, the assumption of first-order shear deformation theory (FSDT) and the principle of virtual work are used to derive the equilibrium equations of cylindrical shells and its boundary condition. We used the concept of weighted residual value to obtain the numerical solution by Moving Least Work method (MLW). In experimental examples, we use different point distribution and different order of base function to validate the applicability of this method. Furthermore, the numerical results are compared with analytical solution to examine the accuracy and the rate of convergence of this method.
