wrong results

Dear Engineers,
Do you know what's the reason for those huge reactions , knowing that the building is 4 stories only with residential loads , dead loads are very big ,I don't know why !!!! and the columns at the roof have big reactions ( like 600 ton ) and there's another columns have big reactions at the roof then the reaction decreases until the basement floor

check material,section and load definition

Check the self weight multiplier in the DEAD load pattern as well.
