RPIM for beam modeling as a 1-dimensional structure

Dear friends

I want to model a beam as a 1D structure using radial point interpolation meshfree method. there are expalnations in the chapter 10 of "meshfree method moving..." by Prof.Liu about PIM for beam modeling and not for RPIM. in PIM modelling we can consider 2*(number of nodes in support domain) terms of polynomials for extraction of moment matrix RQ because of the deflection and rotation dof in each node but it is not applicable for RPIM. what is the solution for overcomming to this problem?  could you help me about the shape function construction for this problem? 



I find hermite-type RPIM can be helpful
