RAM Concept Design Strip and Bending Moment Contour Values Comparison

Leon — Thu, 24 Mar 2022 07:14:55 GMT

Hi,

I'm new to RAM Concept and I've been trying to understand the output.

I have made a trial model for one platform RC structure and try to compare the result output from Design Strip and Bending Moment Contour (also using "Selected Plot Distribution Tool")

I have ensure that the condition is the same between the contour and the design strip.

Below is the screenshot for example purpose,

From what I understand, the design strip total bending moment output at that end section is -96.6 kNm, when I want to get per meter design will be -96.6/2.3 = -42 kNm/m

Whereas when I use the Selected Plot Distribution Tool, the total value is -67.1 kNm, and the per meter design will be -67.1/2.3 = 29.2 kNm/m

Why did I get different result? Or am I interpreting it wrongly?

Thank you for the explanation

OpenSTAAD - Switched Bending Moment Forces Output?

Leon — Thu, 22 Nov 2018 07:44:49 GMT

I was trying to update an old OpenSTAAD excel macro so that it can run on the latest STAAD.Pro CONNECT edition.

While I was trying to extract maximum bending moment member forces I found that the syntax that should've extract max moment comes back with minimum moment instead.

The same goes with min moment that resulted in maximum moment. To better understand this, I've attached something below

This is what I get from the online OpenSTAAD,

I found that the last 4 outputs are, minimum moment, min. moment position, max moment, max moment position. Below is what my syntax looks like

I highlighted the result of max (-73.767kNm) and min moment (170.547 kNm) above. Those two are for MemberNo = 106 and Load Comb = 102.

Instead I found this on the result table where the minimum and maximum moment which is the opposite of what I get from OpenSTAAD.

Can someone explain this to me? Did I misinterpret the maximum and minimum definition?

FYI I'm using STAAD.Pro CONNECT Edition 21.00.02.43

Thanks
