Hello guys I’m having a hard time reading off this chart. I’m given a L2/L1 ratio of 1.55 and a alphaL2/L1 of 0.6, I can follow that to the .65, the books says for B=o is 1 and for B=2.6 is .65. Then you need to follow the dashed line to the right up to 1 and then left to get 0.86 or so. The question is where does the B=0 is 1 comes from, I’m thinking the B=2.5 is between the lines and once I have those values and can follow the diagram to the right to get the load distribution coefficient. I never used this before and there isn’t any good resource on it. I’m k my concern with the exterior negative moment part of the table
