    Installation of outriggers

    Hi, I was wondering what is the installation process of an outrigger system. I know that if installed at early stage in construction, the shrinkage of the concrete can lead to additional stress in the outrigger. If installed too late, the building may be lacking of stiffness during the...

    distribution of winf load in mega braced building with shear core

    Hi Agent666, Sorry for the late reply. Yes I think you're right, it is over-conservative to consider that the core and the braced façade work as two different system individually, and the building should be analysed as a 3D model. Thank you.

    distribution of winf load in mega braced building with shear core

    I have the following building where the flexural deflection is taken by the corner mega columns and mega cross bracing on the facades, and the shear is taken by braced frame at the core. To get the flexure deflection, I take the whole wind load divided by two cause I have two mega bracing...

    analyse of multi bays braced frame

    Thank you very much BA, it's clear now. This is the forces I obtain, it looks very nice!

    analyse of multi bays braced frame

    Yes, indeed there is something wrong in my SAP model. Thanks for your reply BA, I just don't understand how you get the last line "horizontal deflection @TC", and how to you get c = 7/EA ?

    analyse of multi bays braced frame

    Thanks for your reply BA. The example you provided in your last reply, how does it work if I have several bays? And if I consider deformation, would that mean the vertical members would also take an axial load?

    analyse of multi bays braced frame

    Thanks for your replies. You can assume EA constant in all the members. BA, your reactions at the support make sense to me, but are you using a method to find them, or do you just make an assumption? And why wouldn't the two internal supports take any vertical reaction? Also, I'm not interested...

    analyse of multi bays braced frame

    I'd like to get the axial forces in a pinned supported 3 bays braced frame. The frame height is h=8m and the width of one bay is L=7 m. There is only one point load of 1 kN applied on the top left corner. I'm trying to get the reactions at the supports, but I don't know how to do that. I've...
