This paper taking one-hidden layer combined BP network model used in the fault diagnosis of power transformer as a exapmle and on the based of training flow process chart, points out that the number of hidden nodes, initial weight values, training error, the max training times and the order of training samples have different influence on the BP network generalization.

In order to settle some problems involved in applying ANSYS into nonlinear Finite Element Analysis of RC structure,this paper discusses the nonlinear FEM method for staggered joint,incorporating its experimental result.

Beam-special shaped column structure with staggered joint comes into being, with the wide use of special-column-shear wall structure and staggered structure.

Specifications for staggered joint aren t contained in Code for Design of Concrete Structures GB50010-2002,so,the research on shear transfer mechanisms;seismic behavior and shear resistance of staggered joints is urgent.
