Deflection Criteria in RISA3D

[awa5114]

From thread1419-377986

If there are no deflection design rules in RISA3D GUI, can we bypass this by using file input and the following tag?

[.DEFLECTION_RULES] <1>
"Typical" -1.000000 240.000000 -1.000000 360.000000 -1.000000 240.000000 -1 -1.000000 360.000000 -1 -1.000000 360.000000;
[.END_DEFLECTION_RULES]

Appendix D in the help file lists all sorts of criteria we can apply to this tag. Will it incorporate into the design rules to give design suggestions accounting for a maximum deflection established in the input file?

The design rules section is shared information between RISA-3D and RISAFloor. So, what you're seeing in the input file is information that will be used in RISAFloor for deflection optimization and such.

The current version of RISA-3D (14.0) will not do any deflection code check or optimization regardless of whether this information exists in the input file.

JoshPlum, Thanks for the info. I will use the sorting tools available in the spreadsheets to optimize my deflection design.

There is also a Plot option tool that allows you to color code your members based on their deflection ratio. It doesn't give a pass / fail criteria. But, you will see visually pretty quickly which members have issues.

@Josh, that a feature I wasn't aware of. Are you talking about 3D or Floor? I'm not seeing it in 3D.

I'm interested in this as well.

Below is the picture of the plot option setting for color coding by deflection ratio. This is a 3D feature. Like I said, it doesn't give a pass / fail criteria. But, it does give you a good idea which members are having deflection issues and which ones are not.
