1-) THE SPRING LENGTH OF THE COLUMN GIVEN IN THE BASIC APPLICATION PLAN AND THE LENGTH OF THE SPRING DRAWN AT THE VERTICAL EXPANSION OF THE COLUMN ARE GIVEN DIFFERENTLY. (1 cm is not a very big value, but I wrote it for your information) 2-) IF THE ADDITIONAL IRON DIAMETER IS LARGE, ESPECIALLY IN THE ARRANGEMENT OF THE BEAM REINFORCEMENT, THE MUTUAL ADDITIONS MATCHES THE REINFORCEMENT DUE TO THE LOADING LENGTH, AND IT SHALLS THE REINFORCEMENTS TOO MUCH. IT IS TRANSFERRED TO THE DRAWING IN THE SAME WAY. GOOD WORK.
