中文摘要
      建立了结构拆解的力学分析总体思路,提出安全性和再利用性作为结构拆解控制属性,阐明结构拆解的力学分析目标、对象、工况、问题与分析方法;建议了状态离散法和空间分割法作为简化分析方法,将拆解全流程划分为多状态,将各状态的分析划分为局部分析、结构分析和构件分析3类,总结力学分析内容。进一步,筛选了可用的概念分析、解析分析和数值模拟工具,给出混凝土结构和钢结构框架拆解分析简例,并指出未来研究方向及难点,致力于为拆解安全、拆解后构件再利用和拆解效率提升提供研究基础。
英文摘要
      The general idea of mechanical analysis for deconstruction of structures is established.Safety and reusability are proposed as control attributes of deconstruction, and the aim, objects, conditions, problems, and methods of the mechanical analysis are clarified. Besides, the state dispersion method and the spatial segmentation method are recommended as the methods for simplification. In this way, the whole deconstruction process is divided into multiple states, and the analysis of each state is divided into local analysis, structural analysis, and component analysis, of which the contents are summarized. Furthermore, the available tools in conceptual analysis, analytical analysis, and computational simulation are screened, based on which, deconstruction scenarios of simple concrete and steel frame structures are analyzed, and future research directions and difficulties are pointed out, in order to provide research foundation for the safety of deconstruction, the reuse of components, and the enhancement of efficiency.
