non-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

15 صفحه اولPostcritical Behavior of Cables Undergoing Two Simultaneous Galloping Modes
A nonlinear two degree-of-freedom model, describing a flexible elastic suspended cable undergoing galloping oscillations, is analyzed. By using a perturbative approach, the critical conditions occuring for different values of the aerodynamic coefficients are described. Two different type of critical conditions, corresponding to simple or double Hopf bifurcations are found. The nonlinear postcri...
متن کاملInvestigation of Coupling between External and Parametric Resonances in Small Sagged Inclined Cables
The coupling between parametric and external resonances in inclined cables subjected to a motion of an anchorage with components both along and perpendicular to their axis is investigated. Besides posing theoretical challenges, this problem is of practical interest for inclined cables of cable-stayed bridges and guyed towers. First, the state of the art on the subject of multi-modal interaction...
متن کاملA Continuous Approach to the Aeroelastic Stability of Suspended Cables in 1 : 2 Internal Resonance
This paper proposes a continuous perturbation treatment of the nonlinear equations of a cable, which is characterized by possible aeroelastic instability and internal resonance conditions. The objective is to evaluate the influence of stable modes (called passive) usually ignored when discretizing the model. The first step concerns the description of the structural equilibrium path under the ac...
