Nonlinear dynamic P‐delta interaction between TMD and the frame structure under proportional internal resonances

Summary The effect of axial loads on the dynamic interaction of a shear frame and tuned mass dampers (TMDs) is evaluated under harmonic and seismic lateral loads. Taking into account the nonlinear geometric stiffness created by the small and large TMD gravity load on the frame columns, the nonlinear...
