Erratum for “Analytical Solutions for Seismic Fluid-Structure Interaction of Head-Supported Cylindrical Tanks” by Ching-Ching Yu and Andrew S. Whittaker

The following corrections should be made to equations in the Appendix:

Eq. (31) and its description should read:

The external energy consists of the virtual work generated by external forces acting on the tank, calculated using the inertial force of the tank and the impulsive pressure on the tank wall:

Eq. (39) should read:

Eq. (40) should read:

Eq. (41) and its description should read:

Similarly, the solution of Eq. (6) for the impulsive moment at the top, $M_{\mathrm{imp},b,k}$, about the $y$-axis (clockwise direction) is derived by balancing the resultant moment of $p_{\mathrm{imp},b,k}$, distributed on the area of the tank base, $A_b$, with a horizontal distance $r·\cos \theta$ from the center of the head:

Eqs. (4)–(6) and (12)–(14), which are related to the above-mentioned equations and presented in the body of the article, are correct as written.
