Hi, i am a new user in sap2000 from Spain.
There are several question i´d like someone to answer me.
1. how sap2000 does the distribution of horizontal forces (wind and seismic) according to the rigidity?
2. when you define the properties of the center of mass (X and Y directions and rotational moment), that you have to do a hand-made calculate, both directions have to be the same or they may be different instead of the shear walls rigidity direction? For example shear wall only in direction-X and moment frame in direction-Y.
3. SAP2000 can calculate the center of rigidity? If yes, in the joint forces when you define static seismic load in both direction X and Y, how program take account the torsor moment produced if both centers (mass and rigidity) don´t fix?
4. how to define a flexible diaphragm (for example metal deck without concret fill or a sandwich panel on the building industrial roof?
Thanks a lot.
