DISPLACEMENT AMPLITUDES OF FORCED VIBRATION IN DOUBLE-SLOPE SIN GIRDERS WITH SEMIRIGID JOINT

Abstract

Displacement amplitudes of forced vibration in SIN girders with semirigid joint
depend on the stiffness of the girder and the rotational stiffness of joints. Rotational
stiffness has a decisive effect on the overall integrated stiffness
of the girder. In addition, damping caused by semirigid joints produces differences
in the frequency and amplitude of vibration. Therefore, an analysis of oscillatory
motion in double-slope beams with corrugated web with semirigid joints
in the mid-span was conducted. On the basis of dynamic experimental testing
of three simply supported double-slope beams with corrugated web, rotational
stiffness was determined for six joints. Using the theoretical models, namely
the Kelvin-Voigt viscoelastic material and the standard one, differences in the displacement
amplitude behaviour, damping and forces were shown. The investigations
concerned girders with corrugated web for variable rotational stiffness
of the joints under the action of the assumed excitation force.
