Web27 de jan. de 2012 · In regards to mode shapes, with a simplified 3-story 2-D frame with the masses lumped at each story the modes will be as follows: First Mode -- All masses move in the same direction (i.e. similiar to ASCE 7 pseudo lateral force loading) Second Mode -- There will be one "kink" in the deflected shape. WebThe number of modes specified to look for around a refractive index value will affect the modes that the solver finds. If this number is too small, the desired modes may not be found. Often, setting this number to 100 modes will ensure that no physical modes near the specified index have been missed. If more than 100 modes exist, then a larger ...
