This paper is to follow the previous part 10 in which the experimental results of the beam tests to investigate the mechanical properties of metallic skeleton reinforced inorganic matrices structures are shown. In the experiments bending performance of the beams, consisting metallic skeleton reinforced Gypsum paste and Gypsum light weight aggregate matrices or aluminium skeleton reinforced inorganic matrices, are examined. In this paper the experimental data are analysed and the conclusions as follows are indicated. Concerning on aluminium or steel skeleton reinforced Gypsum concrete or Cement concrete matrices beams it is possible to design the components of the structure basically following the current standard of steel reinforced concrete. Yealed strength and stiffness are able to be estimated by the suppositions of the section of the beams keeps plane under the load and the tension side of the matrix is ignored. As for the bond properties between reinforcing bar and inorganic matrices there are two important matters as follows derived from the analytical results. By the round aluminium bar it is difficult to get enough bond strength in inorganic matrices like Gypsum paste, Gypsum concrete and cement concrete. So the deformed aluminium bar is necessary to be used for the skeleton reinforcing the inorganic matrices. To reinforce Gypsum past or Gypsum concrete matrices roundsteel bar is not suitable for its quite little bond strength, then deformed steel bar is to be chosed for matrices made from Gypsum.
