Topic: Meanings and Determination Methods of Load Step, Interval Multiplier,

Hi everyone,
I would like to know what number of load steps , Interval multiplier and step multiplier mean and how they are determined. Are they chosen arbitrarily, or do they vary depending on each problem? Is there a specific formula for determining them? Please explain this to me in detail.

I have encountered a serious problem in my project — I’ve been working on it for several weeks but haven’t been able to solve it. The issue is that I’m trying to verify a beam model based on a published paper and perform the analysis in ATENA. The paper also used ATENA software, but my results do not match those presented in the article.

I have already gone through all the troubleshooting steps, but the problem still persists. One of my main concerns is how to define the loading and the load steps correctly in my analysis.
I would really appreciate it if someone could guide me on this.

Re: Meanings and Determination Methods of Load Step, Interval Multiplier,

Dear User,
Interval multiplier multiplies the loads defined in the interval. Because ATENA works incrementally, the load applied in the interval is divided into steps. So lets say you define load 10kN in your interval, then set the interval multiplier to 2. That gives you 20kN in the interval. Then you define number of steps and divide the total interval load into steps. So when you have 5 step, that gives you 4kN per step. Or you can set the step multiplier 0.4 to get the same effect which is 0.4*10kN is 4kN per step.

If I am not mistaken we are already in touch on our hotline cervenka@cervenka.cz to solve the problem with mismatch of experiment and simulation.
