Solving Practical Engineering Problems of Structural Strength-Application of Dynamic Reanalysis Method and Model Testing
Апстракт
There are numeruos examples of failure of responsible parts of steel structures.
When failure occurs, series of procedures are performed in order to obtain the cause of
failure and to repair the damage. However, prevention of failure should be given higher
importance. That means that one can predict reaction of construction in any unexpected
circumstances, having owerall knowledge about construction. Actually, dynamic
reanalysis method and model testing could give comprehensive insight into structural
behavior of construction. Dynamic reanalysis method implies that the stress is not the
only indicator of weak points in structural design. One should know modal shapes and
natural frequencies, and distribution of potential and kinetic energy in the main modes.
In fact, the main mode shapes show how the structure behaves under some possible
load. Reanalysis method is based on distribution (of difference) of kinetic and potential
energy and involves the transformation of the exis...ting models in the new (better) one.
Model testing represents one of the solutions to obtain the whole picture of
construction behavior and includes creation of sub-scaled model in order to anticipate
the behavior of the real construction, regarding the behavior of the model. Model
testing enables to predict the stresses and deformations, and dynamic behaviour of the
real structure regarding the stresses and deformations of the model, and testing on the
model instead of the actual construction results in a great saving of money and time.
Once again, dynamic reanalysis method and model testing give owerall knowledge
about construction.
