Abstract
This paper presents the results of numerical analysis of hollow floor supported by the column under vertical load and horizontal load. The validity of three different analogue methods were examined and compared. The macroscopic elastic constitutive method (MEC) gave satisfactory predictions but involves an elaborate procedure for determining the equivalent elastic material parameters. The equivalent thickness approach (ETA) gave moderately higher values for the section moment than the exact values. An alternative simplified approximate method based on the effective elastic modulus (EEM) is recommended by the specification. Numerical calculation for section moments by the proposed method were on the safe side and close to exact results. The proposed method could also be appropriate for the column supported structure and the horizontal load.
