• Moment Transfer Rigid Links

    Hello, I have created a STAAD Model in which I created some offsets to simulate how the real moments would look like. Please see the model. In the model, the rafters are on top of the edge beams. In reality, there should be no moment transfer between…

  • Floor Diaphgram and Moment Release

    0245.struc.STD 1) After applying floor diaphgram i am getting following warning *WARNING- ZERO STIFFNESS IN DIRECTION 2 AT JOINT 32 EQN.NO. 188 ***WARNING - INSTABILITY AT JOINT 980 DIRECTION = MY 2) Have i applied the moment release correctly…

  • Moment Releases in Staad

    Hello, I want to understand member releases in staad better. The attached figure has 2 beams in x and z-direction. At the joint, it has a short column going down then another beam and a knee brace. Finally, it has a bottom column fixed to the base.…

  • Design of a Beam perpendicular to and below a top beam

    Hello, I am designing a rooftop dunnage structure in staad pro. In my case, I have beams which are on top of one another in perpendicular directions. So I created a thick post between those beams to act like a stub which has no significance so I modeled…

  • Moment Release in MZ

    Dear All, My doubt is that moment release to be done only in Z direction for the secondary beam? because in staad help manual it is showing that each individual member will takes the local axis so for every beam whether it may be in X axis or in Z axis…

  • Staad pro member specification

    What is the difference between specifying a Member as "Truss" and Releasing Partial Moment at both Ends ? Thank You .

  • RE: Beam Release

    You are only supposed to use moment release if the connection is a shear type connection with no moment transfer. Since you have a concrete structure, you may want to check what the connection of the secondary beam to the primary is like. If it cannot…

  • RE: member release

    As Seth mentioned in his post, it is more of a judgement call but here are some basic guidelines if that helps. For adding more stability to analysis or to restrict drift to a certain limit, one can take advantage of the connection stiffness and the…
