problem with force distribution in beam and column

[lkang6]

Hi,

I established an one bay one story frame, and the purpose was to match the test results. I use springs(with very large stiffness) to connect the shear panel to beam and column. I found in the P-delta curve, the P is almost half to 2/3 of the test results. I checked the force in the beam and column. I found that the stress in the column is large( in plastic range) and stress in beam is relatively small(in elastic range). How can I make the stress in the beam larger??

Thank you so much!!
