Hello! I'm new here in this community and I'm looking forward to discuss my sample model below:
I tried to simulate a curved beam by using a series of straight line segments as shown.
Both ends of the beam are fixed supported.
![]()
Load is only single unifom load:
![]()
During deflection check, there is a big difference in actual deflection whenever I set the deflection parameter DJ1 and DJ2.
(in my model, DJ1 and DJ2 are the nodes at the end of the beam.)
My syntax in STAAD pro is:
DJ1 13 ALL
DJ2 5 ALL
The results are as follows:
CASE 1: w/o DJ1 and DJ2
Max deflection = 0.005mm (almost negligible)
CASE2: w/ DJ1 and DJ2
Max deflection = 208.6mm
Regardless of my loads, there is a big difference in deflection between setting and not setting
DJ1 DJ2 parameter...
Please let me know how to properly assess the deflection for this model.
Thank you in advance for your support!
