After Releasing moment M22, M33 on both end, why Etabs is still designing for M22. Combination = 1.4DL+1.7LL ?? What is Minimum M22 & M33 Col.pdf

Hello everyone, I am looking for some answers to simple questions like 1. What is the inter story drift limit for steel columns , and what is the maximum deflection allowed at the mid span of the column which has axial load and lateral loading as well ? 2. How we decide the end at which moment need to be released and which one like M22 or M33? Does this depends upon the support end and type of support? 3. What is the difference between the pin support and fix support in terms of its application to the model? As lateral meaning is not required its the sense that on which basis we decide that oke we donot model pin support and assign fix support to the model. and then when we are designing base connection like base plate and anchor bolt and position of anchors on the base plate. Does this all only gives us freedom in the fixity of structure at the base like we are free on locating the suitable position for anchors on the base plate or it has to do something else as well ? 4. What about the wind loading? if we calculate the wind load manually and then apply it as a lateral load to the whole structure is ok or we just go as making the areas around the nodes and apply the load only to the nodes and then chk the deformation. What about the wind analysis we do by the help of software how accurate are they as the deformation due to wind is nothing in many cases if you see the analysis report or table...
