There are over 50 ULS Load Combination in the initial model this may lead to an overflow in the final DAM Non Linear

[Mohamed_AbdElAziz4TPC2]

hello everyone,

I am running DAM analysis for AISC360-10 ASD and also seismic based on modal analysis with 5% eccentricity. Robot generates 10 different load cases for seismic to account for the four different eccentricity directions which results in 133 ULS combinations. 

then to account for notional loads the DAM generated combinations are over 400.

the run time is almost half an hour and I get the following two warning/error messages:

1.There are over 50 ULS Load Combination in the initial model this may lead to an overflow in the final DAM Non-Linear

2.There are too many load cases generated. Only 200 are allowed. Adjust parameters to reduce number of load cases

is there any way around this? an alternative to the 2nd order analysis for example?

thanks in advance for your support
