Based on tests and theoretical analysis,the dynamic mechanical model of dissipater is established,and a parameters separated identification method is presented to identify the.

Based on the chroma tog rams obtained from PLC, the separation parameters, such as retention factor k , peak width W, theoretical plate number N, tailing factor Tf, r esolution Rs and separation factor α were obtained.

The optimum design of primary discrete parameters,such as,loads,distance between columns,span,height of columns,gradient of beams,figures of beams and column,which affect the steel weight,was carried out with the least steel weight per unit area as the target and with the restrictions on strength,rigidity and stability for portal.
