I am trying to find the center of mass and center of rigidity calculated by SAP2000. I know ETABS output them in a table format as well as graphically. But I cannot find the similar feature in SAP2000. Please help. Also, for response spectrum analysis done in SAP2000, does anyone know if the...

I have a 15 story concrete building modelled in SAP2000. Is it possible to get the program to tell me the mass and stiffness of each floor, i.e. I need the mass and stiffness matrices of the building. I have assigned diaphragm to each floor. Is it sufficient to tell SAP that I am looking for...

Hi, I am not able to help the current issue since I am new to model wood in SAP. It sounds like you guys are experts and have done it routinely. Can someone help me define wood in SAP, i.e. how to do it? I know how to use section designer for concrete section and adding rebar. Do I just draw a...

I am also trying to define a wood section in SAP2000. From what I am reading, is this the step you take? Define > Materials > (show advanced properties) > Add new material > Material type: other > Directional summary type: orthotropic Once I am in the window, I am confused with all the values...

Hi, I am trying to re-create example 6-009 given in the SAP documentation under HELP. I am trying to see if I can get force and plot force-deformation in the link element. Please see the attached file and help me correct my model. I am not familiar what all the parameters should be. I would...

I am trying to see if I can apply a lateral force, either code defined or self-input, step by step so that I can study the force deformation relationship of the links, supposed to be non-linear. The goal is to make sure that only the links undergoes inelastic deformation with a given lateral...

Thanks. I guess it means that I have to mesh the elements along the length of a beam so that I have multiple meshed joint locations on a beam to simulate the line load.

I am running a time history analysis (a record of a ground motion) through my building. How do I combine the effects of time history to the effects of gravity loads (i.e. dead and live loads) so that I can check the adequacy of the structural elements? Do I combine linearly the gravity loads to...

I used shell element for floor to span in between steel beams. However, I found that only the superimposed loads are transferred onto the beam, not the self-weight. Did anyone ever see that? I checked by displacing loads on the beams.
