Three solution metbods for node displacement of tension and pressure member system in material mechanics were presented and compared.

By using this relations,we can calculate node displacement of the statically indeterminate structure of bar system and to build compatibility equation of deformation of the statically indeterminate structure of bar system which possesses conventional and general features,to avoid painting di.

To figure the arc by polar coordinates is easy to dispose of the parameter of arc and reduces the content of counting,and then the global optimal solution of node calculation is achieved.

The equation of the line on the center of approximate circular arc is obtained,and it can avoids the trouble that numerical solution owns possibility of no convergence and simplifies node calculation of non*.
