Abstract

In this paper, the derivation of element stiffness matrix of a cracked beam-column element is presented in details. An 'overall additional flexibility matrix', instead of the 'local additional flexibiity matrix', is added onto the flexibility matrix of the corresponding intact beam-column element to obtain the total flexibility matrix, and therefore the stiffness matrix. The natural frequencies of a cracked beam-column are then obtained by using the standard finite element procedure. Compared with analytical results, the new stiffness matrix thorugh using the overall additional flexibility matrix can give very accurate natural frequencies.
