Greetings Sofistik community.
I’ll split my question in few consecutive messages because I am not allowed yet to post more than one picture per post.
I am trying to understand this situation:
I made a simple model with T beams forming 3 spans (25m+25m+25m) and a linear one T beam (75m) model with the same characteristics and load converted from Area to a linear equivalent load .
Since it’s a simple model, I calculated reactions and bending moments “by hand” to compare program results as I am still learning Sofistik.
linear load is 15.6kN/m’
R1=R4=0.4x15.6x25=156 kN
R2=R3=1.1x15.6x25=429 kN
M1=0.08x15.6x25^2=780 kNm
M2=-0.1x15.6x25^2=-975kNm
M3=0.025x15.6x25^2=243.75kNm
Here are results for the single beam (number 1) on the first picture.
But it’s getting interesting when I delete model number 2 and leave only number 1.
Now the sum is 1169.7kN with is close to the 1170kN. And moments stay the same.
These two models are not connected. They have same cross section and same load case. Nothing more.
Could someone help me out on this matter and help me understand this behavior. I am a master student trying to learn this software.
Thank in advance!
