【Abstract】 Based on the geometry nonlinearity of four-link mechanism of Pall-type frictional damper, influence of the frame displacement, brace stiffness, damper slip force, size of the damper , angle of the brace and buckling force of the braces on the maximum brace force of an improved Pall-type frictional damper(T-shaped cone plate frictional damper)is studied. And the simple practical formulae of the maximum brace force has been fitted for designer.更多还原
