多类型建筑物周期预测公式的实测对比研究
An Empirical Comparative Study of Period Prediction Formulas for Multiple Types of Buildings
摘要
Abstract
Measuring the dynamic characteristics of constructed buildings and testing the related period prediction formulas are of great significance for the condition assessment of existing buildings in urban renewal.To this end,pulsation method tests were carried out on 22 buildings of different structural types in the Siping Road Campus of Tongji University,and the natural period and damping ratio of the buildings were identified by the random decrement technique,and the identification results were summarized.The measured values of the natural period of the buildings were compared with 17 natural period prediction formulas for the structures,and the period prediction formulas for different structural types were recommended based on the comparison results.关键词
