How can I apply Pdelta analysis for earthquake and wind load seperatley, also why is the small delta command used after performa pdelta text?

An sample model with seismic and wind loading and PDELTA ANALYSIS is attached. The SMALLDELTA at the end of the PDELTA ANALYSIS command instructs the software to include the small pdelta effect. However even if you DO NOT add the SMALLDELTA part, the software now includes the small pdelta effects by default when carrying out a PDELTA ANALYSIS. So basically in the attached model, if you use PDELTA 15 ANALYSIS in lieu of PDELTA 15 ANALYSIS SMALLDELTA, you should get the same results.
