Hi All,
I am an undergraduate student of Final year and performing my thesis on steel onnections. I have performed experiments on beam-to-column connections. The experimental set-up included two beams on left and right side of the column connected at the centre of the column. Two strain gauges were pasted on the column and one on each beam in tension side. 3 LVDTs were used; one with the column to measure central defelection and the other two at the centres of the beams on both sides of the column. Data logger was used to record the data. The load was applied at the centre of the column. Now I am confused to plot the moment-rotation and failure load graphs of specimens. A snap shop of data collected from data logger is attached. Please help me how to use excel cells and the data to plot both" 1. Moment-Rotation curve, 2. Failure Load Graph.
A detailed answer will be highly appreciable. Thanks in anticipation.
