InelasticResponseSpectrum

Purpose

determines the inelastic response spectrum for given acceleration history

Synopsis

[D,V,A] = InelasticResponseSpectrum (Acceleration,MatData,T,zeta)

Description

INELASTICRESPONSESPECTRUM determines the inelastic response spectrum for given acceleration history
  [D,V,A] = INELASTICRESPONSESPECTRUM (ACCELERATION,MATDATA,T,ZETA)
  the function determines the inelastic response spectrum for a given acceleration history in
  data structure ACCELERATION with fields Deltat (time step size) and Value (acceleration value);
  the properties of the force-deformation relation are supplied in data structure MATDATA;
  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, V for velocity, and A for acceleration
  with the row number corresponding to the period and the column number to the damping ratio
