Abstract

Abstract

In this paper,eight top and seat angle connections were selected for parameters analysis with ANSYS 10.0,based on three-parameter power model which was fit for structural analysis．The results were testified with prevenient test data and others M－ curves were got．The suggested value of shape coefficient(n)was got by numerical analysis method of these curves．The research indicated that numerical curves is fitted with test curves and FEA curves perfectly,and the shape coefficient(n)value of those numerical curves have small difference．By contrast of the initial stiffness and ultimate bending moment and those fitting curves,it was suggested that the value of the shape coefficient(n)of top and seat angle connections should be 1.9．
- top-seat angle connections,
- semi-rigid connections,
- shape coefficient,
- three-parameter power model
