Variational Method of Network Structure of Linear Hardening Materials[J]. Journal of Civil and Environmental Engineering, 1998, 20(5): 115-119. DOI: 10.11835/j.issn.1674-4764.1998.05.023.
This paper developed out coordinate equations and equation of strain energy for suspensionand network structure made of linear hardening materials.Then displacements and horizontal forces ofthe network are determined by principle of minimum potential energy.
