    Hi, I am using the Physical Modeller of STAAD Pro Connect Edition V22 Update 12. I have a wall that is shaped as follows. It is thicker on 1 part than the other. I have modeled the different thicknesses of the wall as 2 separate surfaces at the…

    Hi, I'm running a simple structural model to understand the issue I'm facing in a bigger model with Master-slave specification in STAAD. I defined a master node at elevation Y1 and slave nodes at elevation Y1 and Y2. After running the calculation…

    Hi guys, I have a problem. I am using master/slave command to model expansion joints. I have multiple joints in the structure, however only one is not behaving normaly. Master/slave command is used to restrict movement in FX and FY. Master slave command…

  • I want to use RCC floor slab effect on the steel structure of an industrial building. Shall I use master slave command or shall I use floor diaphram command?

    steel quantities especially column size get reduce while considering the rigidity of RCC floor into account. what shall be right approach to consider its effect.

    When master slave is defined between the slab and the beam nodes, the center of the slab and the center of the beam are connected by rigid links. The fixity between the rigid link and the slab/beam would cause hogging moments to develop at the ends of…

    Here are the answers to the questions 1. A steel roof deck without concrete filling or a checkered plate floor are usually not considered as rigid diaphragm and so using master slave ZX will not be appropriate. If you would just want the loading on…

    I agree with what Amir’s observation. Instead of defining rigid master slave connection, I would suggest you to use the rigid floor diaphragm command to model the diaphragms. This would require small changes to be made to the model but it would help you…

    In general if you need to define supports at the master/slave nodes, you should use dummy rigid members in lieu of master/slave.
