Analysis of the Impact and Mechanical Properties of a Damper Made of Hyperelastic Material

Abstract

The proof-load tests are an integral part of verifying the actual behaviour of bridge objects. If a new bridge object is put into operation after construction, it is necessary to verify whether it will behave as it was supposed to when it was designed. In the case of existing bridge objects, it may happen that the bridge has malfunctions or behaves unconventionally due to failures - then there may be a need to reconstruct and strengthen the bridge object, and thus again there is a need to verify its behaviour using a proof-load test. The proof-load test can be static or dynamic. The aim of the paper is to point out the inevitability of the proof-load tests for the real and correct behaviour of bridge structures in ultimate limit state and maximum allowable deformations in serviceability limit states. It is necessary to point to the greatest consequences of resistance, reliability, durability and lifetime of the bridge structures. Using the proof-load tests for new bridges is prescribed by the Slovak standard STN 73 6209.
