Abstract: In this paper the shear deformation of space truss is not considered.According to weighted residual method,a deflection function of space truss is formed in the space of double fifth B-spline function,and is used to calculate deflection and internal force of this space truss by the least-square collocation method.The computed result is very good and the method is easy to use for engineering.
