Triangle uniformly-distributed load pushover analysis

[wfwest]

Dear vesna:
How to realize the triangle uniformly-distributed load pushover analysis?Can you give me an example?

Lets say that you have 2D 3-storey frame with x axis in horizontal direction, the load pattern would be like this:

pattern Plain 10 Linear {
load $nodeTagStorey1 1.0 0.0 0.0
load $nodeTagStorey2 1.0 0.0 0.0
load $nodeTagStorey3 1.0 0.0 0.0
}
