Description

technical field [0001] The invention relates to a technical method for engineering detection and evaluation, and more specifically relates to a method for evaluating the dynamic detection and bearing capacity of high-rise and high-rise structures. Background technique [0002] Due to carbonation of concrete, corrosion of steel bars, repeated and increased wind loads, traffic loads, and lack of daily maintenance, high-rise and high-rise structures will suffer from various structural damages after a period of service, resulting in reduced structural bearing capacity and operating conditions that cannot meet the specifications Require. However, direct research on existing high-rise and high-rise structures affects normal operations and is time-consuming and labor-intensive. Numerical simulation analysis in the studio can not only get rid of the inconvenience of the actual complex situation, reduce costs and improve efficiency, but also can repeatedly study the damage mechanism...

Problems solved by technology

The static evaluation method mainly tests the static parameters of high-rise and high-rise structures, and evaluates the bearing capacity of high-rise and high-rise structures from components to the whole. , the application of the static evaluation method in the evaluation of the bearing capacity of high-rise and high-rise structures has significant limitations

The dynamic evaluation method is mainly to detect the dynamic parameters of high-rise and high-rise structures, and indirectly obtain the performance and bearing capacity of the structure. However, due to the variability of dynamic parameters of high-rise and high-rise structures, there is no complete set of effective high-rise and high-rise structures based on dynamic detection technology. High-rise structure bearing capacity evaluation method, which greatly limits the application of dynamic evaluation methods in the evaluation of high-rise and high-rise structure bearing capacity
