At the same time, the cooperation of the multi-layer frame structure is researched with FEA when the pre-stressed threads are stretching, and the relationship between the beam of stretching layer and the beams of nearly layers is discussed. The layout effect of regular reinforcement in the beam on the pre-stressed effective quantities is also analyzed, and the elementary estimation formula of pre-stressing loss on the multi-layer frame is also deduced according to the pre-stressing loss of one-layer pre-stressed frame structure.

First, based on the relations of stress and strain between the whole medium and its macroscopically isotropic constituents, an explicit relation between elastic matrices of the whole medium and its constituents was derived. Combining the explicit relation of elastic matrices with the strain's relation, two coefficient tensors were defined and analyzed to get a general relation between the hulk and shear modulus of the whole medium under the assumption that all the field variables are in a unified coordinate system. Secondly, combining these relations with the classical Hashin-Shtrikman elastic modulus bounds, four new expressions of elastic medium of the whole medium were obtained and compared with the original hounds. Last, these formulae were applied in the computation of effective elastic moduli of clean sandstone saturated with pore water.
