Steel pipe support column in the vertical direction of the pressure, how to calculate the size of the deflection?
Pressure does not consider the degree of tension, consider the amount of compressionIf it is to do the program, according to the constraint conditions of the bar, check the stability, as if there is a coefficient of what it is
The general structure is the strength, stiffness and stability of these three kind of bar stress load is much smaller than the compressive strength, the strength is no problem of elastic deformation range, but also need to consider the deformation, the stiffness of the problem and then there is stability, according to the material of different types and different constraints, different coefficient formula I don't know.
Material mechanics, deformation formula of tension and compression bar is the same, if you do not consider the bar buckling, plastic deformation and other factors, in the elastic range if equal tension and pressure, deformation is the same: Fl/EA, EA is called tensile (compression) stiffness.
