—This paper aims to propose a mixed algorithm to
simulate the interaction between cable-truss; the study is
focused on the geometric nonlinear analysis since the cables
always have nonlinear behavior under static loads.
By using lagrangian formulations, it is determined the
nonlinear stiffness matrices from the elements cable and truss,
which are assembled to a structure on a global reference system.
The balance of the structures under the action of external loads
is solved by an iterative incremental method, which highlights
the secant method; which gets better approaches to the solution
with a smaller increase in loads. The solution algorithms are
implemented with matlab.
