본 연구는 소성이론의 하계정리를 이용하여 구조설계자의 부재의 응력장에 대한 만족도를 고려한 구조해석 프로그램을 제안한다. 구조물에 작용하는 계수하중과 평형을 이루는 임의의 응력장 중에서 최소노름 응력장을 이용하여 찾아내고, 구조물의 모든 부위에서 부재의 설계내력이 부재력을 상회하도록 부재 단면을 결정하는 방법을 제안한다.

This study presents a new stress analysis method to be substituted for the elastic analysis in such a plastic design procedure. This method is accompanied by an efficient mathematical tool which can be easily handled by personal computer. The method also easily accepts arbitrary strategies by the designer for selection member size.

The paper is devoted to study a mesh-free analysis method of structural elements of engineering structures based on B-spline Wavelet Basis Function. First, by employing the moving-least square method and the weighted residual method to solve the structural displacement field, the control equations and the stiffness equations are obtained. And then constructs the displacement field of the structure by using the m-order B-spline wavelet basis function as a weight function. In the end, the paper selects the plane beam structure and the structure with opening hole to carry out numerical analysis of deformation and stress. The Finite Element Method calculation results are compared with the results of the method proposed, and the calculation results of the relative error norm is compared with Gauss weight function as weight function. Therefore, the clarification verified the validity and accuracy of the proposed method.
