Up to bend or to raise the floor and the beam is one of the reasons for the structure of behaviour that should do a survey to study the changes of behaviour and/or beam while having a payload or payload ever had before.
The deflection or deflection of the beam and floor. The behavior of the structure, one should conduct a survey to study the behavior of the change and / or girders, while the payload. Or have a payload before.
Deflection or buckling of the floor and beam The behavior of the structure factor should be explored to study the behavior change of ground and / or beam while loading Or has been loaded
