摘要:
结构的损伤改变结构的动力特性及动力响应。为保障结构的安全运营需深入了解结构的动力响应情况。用试验的方法研 究了结构损伤与结构动力响应的关系。针对三维框架结构, 用结构中立柱上的不同深度裂缝模拟结构损伤。测试了正弦扫频激 励时结构损伤对结构振动的影响。试验结果表明结构正向振动的最大响应值随着结构损伤的增大而减小。结构侧向振动有相反 的规律, 其最大振动响应值随着结构损伤的增大而增大。在结构损伤程度较大时, 损伤对结构侧向振动的影响远远大于对正向 振动的影响。
Abstract:
Damage in a st ructure al ters i ts dy namic characteri st ics and vibration response .Maintaining safety and integ ri ty of the st ructures due to the catast rophic failure of unde tected damage st ructures requires a bet ter understanding of st ructural dy namic response .In thi s study , the relationship betw een st ructural damag e and dy namic re spo nse is investigated .As a demo nst ration , the ex periment of a three - dimensional steel f rame st ructure w ith dif fe rent damage is validated .The st ructural damage in the f rame st ructure is simulated by saw -cut ting a crack w ith the different depths across the w ho le w idth in the pillar of the st ructure .The sw eep -sine re sonance test is applied to study the relationship between structural damage and dy namic response .The ex perimental resul ts indicate that structural reso nance response of exciting direction decreases w hen st ructural damage increases , but structural resonance re spo nse o f side directio n increases .Ef fect on st ructural resonance response of side direction by st ructural damag e is g reeter than that of structural resonance respo nse of exciting direction
