thank you for this video... hoping for more warning and error resolution videos ^^

good presentation, can't wait for next session

Very soon!

for dummy supports, is it required to model the base plate with zero gap and with coeff. of friction value (metal vs. concrete)

[@oceanofknowledge4533]

with dummy support resting on ground it is better to define 0 gap in +Y direction, and define gap in X n Z direction as per guides installed on base plate...

@@oceanofknowledge4533 May I know what is the difference between +Y without gap and +Y with 0 gap? Thanks

[@oceanofknowledge4533]

I have checked if you left gap blank without entering 0 CAESAR also reads it as 0, nevertheless I believe it's better to write 0 rather than left it blank, because it helps u during review of your model... U know u intentional wrote 0 gap not forgot it entering...

@@oceanofknowledge4533 Thanks for the reply, another issue is the angle of the reducer. I believe there is no impact on the structural results (displacements, restraints, element forces) when you leave the value blank or enter a specific value (within the range of 5deg to 60deg). The angle value is basically used to calculate the reducer's SIF. For B31.3 before 2020, SIFs=1.0, however, B31.3 2020 using B31J shows specific equations to calculate SIFs. Correct me if anything is wrong.

Very vey good explanation.. sir can we have lecture on surge and PSV line supports. thanx in advance

[@oceanofknowledge4533]

Glad you like it, i have noted your topic will create video on PSV reaction force and design, stay tuned to channel.

for Eccentric Reducers there is alpha value. How about for concentric reducers? shall we input alpha value as zero?

[@oceanofknowledge4533]

No, Alpha is actually the degree at which larger diameter is decreasing to smaller diameter. Smaller value of Alpha will result in greater length of reducer and gradual transition from larger to smaller diameter. Where as greater value of Alpha will result in smaller length of reducer and sharp transition. In our video for eccentric reducer since Alpha was not given we were able to almost accurately deduce it with calculation. We'll explain how to accurately calculate Alpha for both concentric & eccentric reducers, or the easier way is let CAESAR II calculate it. If we left it empty CAESAR II will calculate it by default.

Great 👍👍
