First of all, does the results vary if I use SMALLDELTA instead of PDELTA and also how can I get results for LARGE PDELTA. In case of load combinations do I have to use the text PDELTA ANALYSIS & CHANGE after each combination. I have attached a model here, can anyone revise it for LARGE PDELTA analysis for all the load combinations & is the variation in results prominent from SMALL PDELTA analysis & analysis without PDELTA. Also I would like to know about the theory taken into consideration for large PDELTA analysis & SMALL PDELTA analysis.
