1. Métodos construtivos de pontes estaiadas - estudo da distribuição de forças nos estais. / Construction methods of cabled-stayed bridges - study of cable forces distribution.
Cable-stayed bridges consists of a deck supported by inclined and straight cables anchored to the pylons. This type of structure is highly hyperestatic and quite sensitive to the construction sequence, but yet supporting a considerable range of loadings from the cable installation due to the deck flexibility. Nevertheless, due to the deck flexibility the cab

2. Influência das vibrações do cabo na instabilidade aeroelástica de uma viga simples estaiada. / Influence of cable vibrations on the aero-elastic instability of a cable-stayed beam.
This paper is concerned with determining wind critical velocities and post-critical vibration amplitudes in a cable-stayed beam, under wind-rain condition. It is considered the cable sag due to the dead load plus the non-linear coupling between the vibration of both the cable and the beam. Three modes are of special interest, namely the first global mode (be
