Abstract

Structure reliability appraisal assessment structure in the future for some time to complete the intended function under specified conditions. The reliability of the identification of the structure, including security identification with the normal use identification of two parts, the paper mainly studies masonry structural safety identification methods, most of the security structure identification using the traditional experience of law, and human factors often play a decisive role, the identification results often by expert personal preferences and experience with the uncertainty. With engineering examples, integrated use of structural reliability theory, AHP, Extension theory to study the existing masonry structure security identification method is proposed based on a set of masonry structure security Extenics theory identification methods, qualitative methods into quantitative rating method, combined with engineering examples to verify its correctness. Of six chapters in this article are summarized as follows: The first chapter on the purpose and significance of this study, an overview and analysis of the research status of the subject, the analysis of masonry structure identification methods, summed to determine the content and goals of this research. The second chapter describes the structure of security identification Extenics theory, the primitive concept Matter Element Extension sexual, extension set, the correlation function Extenics related theories to analyze the characteristics of the correlation function its applicability, the correlation function with characteristic function comparisons of the advantages of the correlation function. The third chapter describes the basic principles and steps of using AHP to determine the vector of factor weights, to establish a hierarchical structure model of the impact masonry structure security factors, five-scale method to construct the same level evaluation to determine weight vector matrix, using the improved analytic hierarchy process to determine the factors that affect masonry structure security. The fourth chapter analyzes the various factors affect the security of the masonry structure, matter-element model apply to the safety evaluation of masonry structures, to establish the correlation function of the various sub-factors, introduced the work steps. Chapter Zhuanghe City teaching building of a masonry structure security identification, for example, the paper concludes with engineering examples combined its specific application, and this method of identification of the conclusions to be compared with the existing methods of identification of the conclusions to verify the correctness and feasibility of the proposed method. Chapter summary of the full text, and pointed out the importance of this project is to continue to study.
