Analytical Model for Multiribbed Composite Wall Structure with Open Frame at the Bottom
Publication: Journal of Engineering Mechanics
Volume 143, Issue 2
Abstract
Multiribbed composite wall structures with an open frame at the bottom (MRCWSFB) have been developed in recent years and increasingly used in China. This paper develops an analytical model to analyze vertical stress distribution of a wall beam in the MRCWSFB. The multiribbed composite wall can be equivalent to the elastic foundation and the trimmer beam can be treated as inverted elastic foundation beam. Therefore, the vertical stress distribution of the wall beam can be obtained using the Pasternak double-parameter elastic foundation beam theory. The accuracy of this model is verified against the results from finite-element analysis. A parametric study is then carried out using the analytical model to study the effects of the section of the frame column, section height of the concealed beam, wall depth, division of the ribbed frame, and the Young’s modulus of filling blocks on the internal forces of the bottom trimmer beams, where the influencing factors are identified.
