Linear scaling
Linear scaling
(OP)
I came across the phrase linear scaling when reading some material about structural analysis and load distribution and I have not been able to find out what the phrase means. Does anyone have a definition? I have asked a few people at work and they are not familiar with the phrase, so I am wondering if it is also known as something else? Thanks for your help.






RE: Linear scaling
Say I know that the deflection for a steel beam due to 1.5 kips/ft is 1.25 in. and want to know the deflection due to 2.0 kip/ft. Linearly scaling it up: 1.25 in. (2/1.5) = 1.67 in.
Loads are linearly scaled up using load combination factors.
If the moment of inertia for a 6 in. wide plate is [whatever], then the MOI for an 8 in. wide plate is [whatever]*(8/6)
If a 2 lb sinusoidal load causes 0.5%g acceleration, then a 3 lb load causes 0.5*3/2
The examples are endless.
