Research On The Structure Dynamic Perfomance Testing And Evaluation

This paper firstly introduced the new developments of engineering structuredynamic performance detection technology, the research status at home and abroad,existing technical achievements, my research purpose, method, content and significance,and then combined with the practice of our research, reference of the existingtechnology and related technical regulations, rules, regulations and other detailedintroduces the dynamic detection, the applicable scope of the testing instrumenttechnical parameters requirements, testing procedures, methods, testing of theconsultation, real-time data preservation and finishing, dynamic performance evaluationsystem, etc., Finally through several engineering examples demonstrated the reliabilityof the research results and the prospective.The paper proposed intelligent outcomes about the core content of the structuredynamic performance detection techniques and evaluation, including: automaticarrangement of measuring points in the working principle, method, automatic checkingand testing the matters of attention in the implementation of the project, specially madethe detection scheme form; Detection scope of application of argumentation andqualitative recognition; data preprocessing by the surrounding environment, the signaltransmission and other uncertain factors affected; modal parameters damageidentification of tall buildings and large span space structures, etc. These resultsprovided powerful references for the development of dynamic performance detectiontechnology.Of course, I also recognized that the development of the technology still has manyproblems. Such as dynamic performance detection of objects still need further argument;Automatic metering calibration need to set the standard; How to improve the terminallayout; How to collect the effective data; The comprehensive analysis of the damageidentification, etc. But thinking of its special advantages, low cost, with the perfectionof the system, combined with the current static testing technology it will providepowerful weapons for engineering structure reliability appraisal.
