This paper presents a new analytical solution to free transverse vibration fo straight beam with elastical supports (including rotational elastic supports)of arbitrary spans. The analytical solution of the dynamic response of the forced transverse vibration of the beam is obtained through regarding the reaction forces (including the reaction moments) of the elastical supports on the beam as the unknown external forces acted on the beam and the undecided integral constants are given by the boundary condition...

This paper presents a new analytical solution to free transverse vibration fo straight beam with elastical supports (including rotational elastic supports)of arbitrary spans. The analytical solution of the dynamic response of the forced transverse vibration of the beam is obtained through regarding the reaction forces (including the reaction moments) of the elastical supports on the beam as the unknown external forces acted on the beam and the undecided integral constants are given by the boundary condition of the beam. The frequency equation is described by a determinant which is derived by the linear relationship between the reaction forces (including the reaction moments) of the elastical supports on the beam and the displacements (including the rotational angles) of the beam at the supports and its order is equal to the number of the elastical supports. The mode shape function is described by a unified analytical representation. The rigid supports are the special cases of the elastical supports in this paper. The frequency equations at several common boundary conditions are performed and finally a numerical example is given.

In the design of a curved girder bridge,adopting the big external girder will be more reasonable because the external girder of the curved girder bridge bears more loads than inner girders. In this paper,a detailed analysis of curved girder bridges with the big external girder is made by using the spring coefficient method of redundant rigidity and В.З.Впасов equation of curved girders and taking the warping and twisting effects into accounts. The calculation formulae of elasticity supporting reactions are...

In this paper,a detailed analysis of curved girder bridges with the big external girder is made by using the spring coefficient method of redundant rigidity and В.З.Впасов equation of curved girders and taking the warping and twisting effects into accounts. The calculation formulae of elasticity supporting reactions are deduced, then the transversal distributing influence line of loads is obtained.The presented results provide a theoretical basis for the load calculation of such structures.
