Figure 15
The illustration contains two scientific line plots labeled (a) and (b). For each plot, the x-axis is labeled “Time [seconds],” ranging from 0 to 0.6 with an interval of 0.1, and the y-axis is labeled “Displacement [millimeters],” ranging from negative 500 to 100 with an interval of 100. Each plot has two lines: a solid black line for “Original” and a solid red line for “Optimized”. Legends on both plots identify the line styles. Left plot (a): Both lines start at zero; there is a sharp negative drop near 0.1 seconds. The black line reaches about negative 460 millimeters minimum; the red line reaches about negative 350 millimeters. Both then increase slightly and stabilize, with the red line consistently higher around negative 300 millimeters and the black line around negative 400 millimeters. Right plot (b): Both lines follow nearly identical patterns to plot a. The black line drops to a minimum near negative 430 millimeters; the red line reaches about negative 310 millimeters. Both recover and flatten, with the red line curve always above the black line. Note: All the numerical data values are approximated.Evolution of displacement in axis , as a function of time for: (a) node 97 and (b) node 1937. Source(s): Authors’ own creation
