In the spatial structures, shapeplays an important role about the load carrying capacity, In this research, the following three items were investigated :1. Theoretical Studies on the Shape GenerationBasic equations for the structural analysis are equlibrium equation, compatibly equation and constitute equation. Based on these equations, shape analysis such as (1) shape analysis of unstable strncture, (2) shape analysis of structure with self-equilibrium strss state, (3) shape analysis with constraint condition of stress, (4) shape analysis of structure with prescribed displacement mode, and (5) shape analysis of structure in the vicinity of critical point are theoretically formulated and analytical methods for these shape analysis are presented.2. Application of the Theoretical Studies to the Structural Design of a Hybrid StructureA new type of structure which is consisted of both truss members and rigid structure is proposed. To estimate the structural behaviors, the following items are theoretically studied (1) classification of stable and unstable hybrid structures, (2) stabilization process of unstable hybrid structure, (3) existence condition of pre-stress, (4) stabilization of the introduction of pre-stress and (5) analytical method for stress and displacement.3.Theoretical Studies on the Shape ControlFor static and dynamic systems, shape onutrol structure can be defined as shape of structure is controlled by actuators, etc. in order to satisfy the prescribed shape condition. The present research presents an arrangement theory of actuators, numerical analysis of shape control structures due to the static and the dynamic loads.

在空间结构中，Shapeplays在载荷能力方面起着重要作用，在这项研究中，研究了以下三项：1。关于结构分析的形状生成层方程的理论研究是equlibrium方程，兼容方程并构成方程。基于这些方程式，形状分析，例如（1）形状分析不稳定的strncture，（2）具有自平衡strs状态的结构的形状分析，（3）形状分析具有压力约束的形状分析，（4）具有处方位移模式的结构的形状分析，以及（5）临界点的结构分析在临界点上是构造和分析方法的结构分析。提出了理论研究在混合结构的结构设计中的应用，该结构由桁架成员和刚性结构组成。为了估计结构行为，从理论上研究了以下项目（1）稳定和不稳定的杂交结构的分类，（2）不稳定杂交结构的稳定过程，（3）预压的存在条件，（4）（4）稳定在压力和移位的稳定中，稳定了压力和置换方法。为了满足规定的形状条件，定义为结构形状。本研究提出了执行器的布置理论，由于静态和动态载荷而导致形状控制结构的数值分析。
