Fig. 10.
Panel a shows normalised displacement Y 0 over D against zeta b. Zeta b ranges from 0 to 1 and normalised displacement ranges from 0 to 0.10. Present study data points cluster near 0.40 to 0.50 with displacement values near 0.01 and near 0.77 to 0.90 with displacement values between about 0.03 and 0.07. Equation 7 increases gradually from 0 at zeta b 0 to about 0.01 at 0.40, then rises sharply after 0.80 to above 0.10 near 1.0. Panel b shows normalised displacement Y 1 over D against normalised displacement Y 0 over D. Both axes range from 0 to 0.07. Present study data points increase almost linearly from about 0.011 to 0.064. Equation 8 follows a near linear increase from 0 to about 0.07 across the plotted range.Normalised lateral displacement relationships between: (a) Y0/D and ζb, valid for and (b) Y1/D and Y0/D
