Even though the concrete mix is designed to have a uniform strength throughout the entire member, casting, as well as the basic characteristics of the concrete materials, could yield a non-homogeneous constitution, resulting in a concrete strength gradation as a function of the depth of the member. A functionally continuous and smooth strength gradation of the concrete member along its axis or section is defined as graded concrete. The objective of this research is to analyse the influence of two different concrete compressive strengths that composed the graded concrete member. The study is split into two parts: the experimental work describing and identifying the mechanical properties of functionally graded concrete and the finite element analysis implementing these property variations in a model. The results showed that the concrete gradation influenced the ultimate strength of a member negatively and altered the stress distribution and displacement response of the specimen.

A seismic enhancement effect of pile foundation equipped with a low-cost frictional type seismic ... more A seismic enhancement effect of pile foundation equipped with a low-cost frictional type seismic isolation bearing device is studied. The frictional mechanism is resulted from two surfaces contact between a half steel sphere mounted at the pile cap and the corresponding inner steel sphere embedded in the footing of superstructure. In order to verify the mechanical behaviors of the pile with frictional type seismic isolation bearing device, tests on the piles subjected to earthquake excitations in 60% scaled model has been performed. By installing the rotational friction bearing at the cap of the pile foundations, the unfavorable oscillations after the peak ground motion responses could be eliminated. The rotational friction bearing is found to be very effective in releasing the internal energy transferred from the pile foundation to the superstructure.
