The prestress developing of tensile cable-net structures is a state transforming process from the initial
unstressed state to the final prestressed state, and it is rather complicated because the elastic deformation is
normally coupled with the kinematic mechanism movement. Firstly, the basic equations of prestress developing
by moving boundary joint are derived from the total potential energy equation. Secondly, the presumed initial
tension is proposed to impose into the elements and avoid the singularity of global stiffness matrix. And the
self-stress mode which is calculated from the equilibrium matrix with singular value decomposition is employed
as basically presumed initial tension. By applying boundary movement increment, an iterative computation is
developed to calculate the updating geometric configuration and tension evolution. Finally, the MATLAB program
is coded from the presented method, and numerical examples indicate that this computational method is effective
and has theoretical significance and valuable guide to design and construction of tensile cable-net structure.
