 The result of reactions and member forces has huge difference in Repeat Load and Combination Load. 
 Which one should be used for designing members?

The load is being generated in Load case 1 and 2. If you want these load cases to be used in REPEAT load combinations, the static seismic load cases should have PERFORM ANALYSIS followed by a CHANGE command. On doing this, you will see-&lt;/p&gt;

&lt;p&gt;Repeat Load is giving results too low.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Repeat Load vs Combination load- Both gives different result when used with seismic load.

I also understand repeat load is more practical.&lt;/p&gt;
&lt;p&gt;But&amp;nbsp;I am just a bit confused, as have seen many people using Combination Load for concrete member design.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Repeat Load results in lower section and Rebars as compared to combination load. &lt;/strong&gt;I just want to be sure before moving forward with repeat load case design.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Repeat Load vs Combination load- Both gives different result when used with seismic load.
