Evaluation And Optimization Of Reinforcement Schemes For Historic Building Structures

China has a large number of historical building resources,but the current status of protection is not optimistic.Although in recent years,our country in the history of building protection and repair research has made some achievements,but in the process of protection and restoration of the reinforcement program is also mainly used in the experience level,few experts and scholars from the economic,technical and social And so on the selection of reinforcement programs for systematic,theoretical and professional research.Therefore,this paper argues that the rationale provides the rational choice tool to assist the optimization of the reasonable,effective and quick judgments as a starting point,to avoid the blind commercial development of historical buildings,and thus to protect the purpose of historical buildings.Through the analysis of a large number of relevant research literature,combined with field research,the study on the optimization of the historical building structure reinforcement scheme is carried out.The main contents of the study include the following aspects:(1)Through the investigation of the representative historical buildings in Tongli Ancient Town,the author analyzes and evaluates the quality,appearance and utilization of the historical buildings in Tongli Ancient Town,and summarizes the existence of the reinforcement methods adopted by the local residents in the reinforcement of Tongli Ancient Town Of the problem,including the abuse of modern materials,reinforcement process,reinforcement process to destroy the ancient town of historical style,affecting its original historical value.(2)Constructing the index system of reinforcement scheme of historical building structure by means of mathematical methods such as importance index and Delphimethod;clarifying the connotation of each index,laying the foundation for the assignment of weights of each index;Score standards for the application of the index system to create a quantifiable basis.The weight of the optimal scheme of the reinforcement of the historical building structure is determined by the comprehensive weighting method,which provides a powerful guarantee for the establishment of the optimization model of the reinforcement scheme of the scientific system.Through the improvement of the traditional TOPSIS method,the improved TOPSIS The model of historical building structure reinforcement scheme is a kind of new method and method for selecting scientific and reasonable and economical reinforcement scheme.(3)Taking the Middle East railway complex Gongzhuling Russian architecture as an example,this paper studies the reinforcement scheme of historical building structure.Based on the results analysis and investigation,three reinforcement schemes are proposed,and the optimal scheme is selected according to the evaluation model of the historical building structure reinforcement scheme.
