ElasticResponseSpectrum

Purpose

determines the elastic response spectrum for given acceleration history

Synopsis

[D,Psv,Psa] = ElasticResponseSpectrum (Acceleration,T,zeta)

Description

ELASTICRESPONSESPECTRUM determines the elastic response spectrum for given acceleration history
  [D,PSV,PSA] = ELASTICRESPONSESPECTRUM (ACCELERATION,T,ZETA)
  the function determines the elastic response spectrum for a given acceleration history in
  data structure ACCELERATION with fields Deltat (time step size) and Value (acceleration value);
  the periods for the spectrum are specified in row vector T ( default= [0.001 0.1:0.1:5] );
  the row vector ZETA contains the damping ratio(s) ( default=0 );
  the response spectrum values for the periods in row vector T are returned
  in arrays D for displacement, PSV for pseudo-velocity, and PSA for pseudo-acceleration
  with the row number corresponding to the period and the column number to the damping ratio
