概要：
During construction of membrane structures, the structures change the shape considerably and both of slack and tense area intermingle in the structures. The paper proposes a frame unit mainly composed by elastic-catenary cables that can simulate the large displacement behavior of compression-free membrane. The frame unit possesses nearly equivalent strain energy to the uniform strain element in the tense state, and keeps tensile field in the slack state. When a membrane structure is modeled in the frame units composed by cables with positive stiffness, the Newton-Raphson’s method gives the equilibrium solution after large displacement by not many times of iteration under stable convergence.
