The stress stiffening capability of the element is used. Harmonic response analysis is used to determine the displacement response to the lateral force F2. The harmonic response is displayed with the time-history postprocessor,
POST26, to show the excitation of the odd-numbered frequencies at peak displacement amplitudes. Results Comparison
