The use of equivalent beam models to estimate the dynamical characteristics of complex tall buildings has been investigated by several authors. The main reason is the structural response estimation to stochastic loads, such as wind and earthquake, using a reduced number of degrees of freedom, which reduces the computational costs and therefore gives the designer an effective tool to explore a number of possible structural solutions. In this paper, a novel approach to calibrate the mechanical and dynamical features of a complete 3D Timoshenko beam, i.e., describing bending, shear and torsional behavior, is proposed. This approach is based on explicitly considering the sub-structures of the tall building. In particular, the frames, shear walls and lattice sub-systems are modeled as equivalent beams, constrained by means of rigid diaphragms at different floors. The overall dynamic features of the tall building are obtained by equating the deformation energy of an equivalent sandwich beam with that of the selected sub-structures. Finally, the 3D Timoshenko equivalent beam parameters are calibrated by minimizing a suitable function of modal natural frequencies and static displacements. The closed form modal solution of the equivalent beam model is used to obtain the response to stochastic loads.

“…In a first approach, one of the possible candidate phenomena considered responsible for the aerodynamic loading leading to instability was galloping in one of its several forms. In this regard, different types of galloping of overhead transmission lines or other long span cables were reported and analyzed experimentally or theoretically by Davis et al (1963), Simpson (1965), Dale et al (1968), Bartoli et al (2006), Macdonald and Larose (2006), Macdonald et al (2008), Hung and Yamaguchi (2014) and Zhou and Liu (2015).…”

“…The excitation mechanism of cables of cable-supported bridges and associated boundary conditions have been extensively researched in the last fifteen years and reported in many papers (Bartoli et al 2006, Impollonia et al 2011, Jakobsen et al 2012, Matsumoto et al 2001, Wardlaw 1990. A thorough analysis of the dynamic wind response of such structures requires that the vortex-shedding excitation, the buffeting due to wind gusting, the dry inclined cable galloping instability, the wake interference, and the rain-wind induced vibrations should be considered.…”
