- Abstract:
- For long-span space truss structures, it was very important to accurately simulate the nonlinear performance. Based on the increment of UL method of differential equation, the stiffness matrix of the space truss considering geometric nonlinear was deduced. The high order nonlinear truss element was developed in the OpenSees platform. The realization of the element, the static and dynamic calculation of TCL command flow and the nonlinear algorithm of iterative process were put forward. Several kinds of truss structure under the action of nonlinear static and seismic nonlinear dynamic analysis were carried out. And the results showed that the element could reflect the strong nonlinear behavior of trusses.
