Detection of spalling using vibration data

This project presents a study in the effect of spalling to dynamic parameters such as natural frequencies and mode shapes. Numerical example of a slab will be used as an example in this study. The slab will be modelled using ANSYS 11.0 and various types of spalling are imposed. The changes of vibrat...

Numerical example of a slab will be used as an example in this study. The slab will be modelled using ANSYS 11.0 and various types of spalling are imposed. The changes of vibration parameters are monitored and compared. The sensitivity of modal parameters to spalling is determined using the flexibility method. Since frequency only can indicate the existence of damage, mode shapes are needed to determine the location and severity of damage. Therefore in this study flexibility method is employed. Based on the results it is found that by incorporating mode shapes using flexibility method, damage location and severity can be obtained. 2010-07 Thesis http://eprints.utm.my/id/eprint/11368/ http://eprints.utm.my/id/eprint/11368/4/NadiaHajihasaniMFKA2010.pdf application/pdf en public masters Universiti Teknologi Malaysia, Faculty of Civil Engineering Faculty of Civil Engineering
