Identification of structural parameters based on measured flexibility;

Damage identification of main girders for long span cable-stayed bridge based on flexibility matrix;

Study indicates that flexibility matrix is a kind of powerful method of structure damage detection.

The explicit unified expression of element compliance matrix and the explicit formulations for the displacements of element nodes are derived from the concept of base forces.

The process of elastohydrodynamic analysis combined with compliance matrix was described,and an elastohydrodynamic calculation was done using ORBIT as tools with compliance matrix on conrod big-end bearing of a 4 cylinder in-line diesel engine.

An explicit expression of element compliance matrix of the finite element method for arbitrary meshes is derived using the base forces.

A flexibility matrix method for damage identification of truss structure;

The conventional damage indicator methods such as flexibility matrix method have difficulty in dealing with the damage identification of complex continuum structure such as multi-span beams.

The finite element method is used to form a flexibility matrix of a structure.

In this paper,based on the simulation analysis of continuous box girder bridge,comparative analysis of curvature mode method and flexibility matrix method is studied on three aspects of sensitivity on damage detection,accuracy on detection and localization and anti-influence of test error.
