Mechanical Analysis and Fundamental Philosophy for Deconstruction of Structures

Abstract:

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.
