The study of the natural vibrations is the basis of risk evaluation. Based on numerical simulation technology, some influence factors such as different restriction means including the setup of vertical support or fixed connection between pylon and girder, and elastic constraint along longitude of girder, as well as whether setting the auxiliary piers, the location and the number of the auxiliary pier and the changes of the dead load are chosen in order to study in depth the effects on the first-order longitudinal frequency, first-order vertical-bending frequency, first-order transverse-bending frequency and the first-order torsional frequency of self-anchored cable-stayed suspension bridges. The results obtained here have an important guiding significance to optimize structure design and defend risk.

The paper discusses issues related to the dynamic parameters of the metro train influence on the building construction of Ukraine Cinema & Concert Hall complicated in terms of construction located in Kharkiv City. The hall roof is of peculiar complexity made in the shape of hyperbolic paraboloid hung to the cable roof system and supported by the inclining reinforced concrete arches. Using the equipment by DIAMEX 2000 LLC we have measured vertical and horizontal forced vibrations in the most relevant points of the casing. Natural vibrations were defined by creating dynamic impact of the falling load weighing 10 kg from a height og 2 m. The vibration parameter measurement was carried out by means of Ahat-M vibration analyzer. As a result we have obtained amplitude-frequency characteristics of the forced vibrations caused by metro train movements. The frequency of base and obertones is within 30-50 Hz. At the same time, vibration amplitudes is up 200-350 pm. Specific range of vibrations leads to the occurrence of the for framing roof framing (concrete and steel strand guy ropes), noise penetrating into the hall significantly worsens operating characteristics for the spectators. A special calculation of guy rope element taking into account fatigue factors has been made.
