Control Node

[Kirkaguel]

As per ASCE 41 requirement the control node should be at the center of mass of the roof but this is hardcoded by the program, is there a way that we can printout the exact location of the control node for verification purposes?

Apart from the automatic selection of the control node, according to the requirements of the selected code, there is the possibility of the definition of the control node at the center of a specific slab (Building Modeller settings>Structural Modelling tab). However, it is not possible to directly specify the coordinates of the control node.

Thank you for the reply Seismosoft, However not all cases that the center of mass will be at the center of the slab for example in the case that we have a floor system with openings from elevator shaft or staircase the center of mass will be shifted somewhere. If the whole floor system is declared as rigid diaphragm I assumed that all the masses at that particular floor will be lumped and applied at the calculated center of mass. Can this center of mass be printed out?

Unfortunately, this printout cannot be done with the current version of SeimoBuild.
