In order to look into the causes of fire response and post-fire bearing capacity of the steel tubular columns protected with different materials, the fire test was conducted for a set of circular steel tubes protected with different materials such as gypsum fireproof panel, bamboo plywood and the ordinary lumber core plywood, and the steel tube without any protective material.
The test results show that gypsum fireproof panel has the best fire protection characteristics, the ordinary lumber core plywood and bamboo plywood can also retard rising of the surface temperature of the steel tubes during the initial 35min although they are combustible materials.
It is found that the post-fire bearing capacity of the steel tubes protected with different materials varies evidently, and the maximum value of response temperature has the greatest effect.

In recent years, with the wide application of functionally graded materials (FGMs), researchers have also turned their attention to the dynamic characteristics of the plate and shell of functionally graded materials.
Woo[13] studied the nonlinear free vibration behavior of plates made of functionally graded materials, discussed the effect of material properties, boundary conditions and thermal loading on the dynamic behavior of the plates.
The Voigt’s rule was used to estimate the effective material properties from the volume fractions and the properties of the constituent materials.

The article presents methods of applied mechanics for solving problems in materials science, in particular to predict the dynamic strength of concrete with low-rigid dispersed materials.
Such materials, as foam glass, cellular polystyrene, expanded clay sand and crushed brick were considered as low-rigid components.
