RCC Design of beam

Hi, is there any way or how to add moments on Beam acting due to load on it.?

Describing briefly, lets say there is an existing structure. Now there is a provision of new wall/ panel. so i want to check that "the base moment acting on that wall due to wind load will be taken by beam or supporting RCC frame". For analysis part i can take Dead load/live load of that element but what about the Moments Acting at the base through out the length, how to add this in analysis?
