Once20036 Thanks for the suggestion, turns out we looked into similar thing. We ultimately designed bracing systems the a particular stiffness such that it transfers the load we want it to transfer.
BAretired Thank you for your response. I see some concern in your approach, If we solve this system of equation, it will always end in R1,R3= 0 and R2=P (I'm assuming your second equation was meant to be R2 = P-1.429R3) meaning no contribution from outer girders. I'm using slightly different...
I'm designing a transfer girder which has a tight deflection criteria and the depth of girder is restricted by some ARCH constrains. I'm wandering into a idea of using 3 identical parallel girders( transfer column sits on middle girder)to distribute the column loads and use the stiffness of all...
