Hi,
Anyone, has read these lecture notes:
http://www.colorado.edu/engineering/cas/courses.d/NFEM.d/NFEM.Ch08.d/NFEM.Ch08.pdf
I've programmed FEM analysis for a deep truss element-but find my assembled stiffness matrix after application of boundary conditions singular--
My question is, whether can we apply above stiffness matrix (as in the chapter) for a truss as shown in the attached figure (jpg file)?
plz help
