Summary
Using the GLOB-LOC model for damaged laminate stiffness matrix calculation and applying the described methodology for effective elastic properties back-calculation the following conclusions were obtained
a) intralaminar cracks do not affect the effective longitudinal modulus or Poisson’s ratio of the damaged layer;
b) the effective elastic constants have linear dependence on crack density and the rate of reduction in normalized form depends very weakly on the used material and the layer thickness ratio;
c) the crack density increase with applied strain in damaged layer can be roughly considered as linear with slope which may depend on the damaged layer thickness;
d) the calculated linear dependence of effective properties on crack density and the experimental linear dependence of crack density on strain can be used to calculate the effective elastic constant dependence on strain.

Keywords: frame structures; floor deformation; static analysis; state space method
Abstract The piecewise continuum technique was used for the frame structure and a series-parallel system was taken for the mathematical model for the structure in which the deformation of floor slab had to be considered, and its state space equations were derived.
The material constant is E=3.25×104MPa, G=0.4E.The displacements and internal forces of some floors calculated in this paper are tabulated as Table 1.
