Concrete creep is very complex, related to time and the history of stress, what’s more, there are many changes in material composition and application form structure because of modern concrete.
However, the models can simulate the coagulation materials to test in a finite number of age (usually age 5, 6), impossible to obtain creep value from any time period.

The soil material is assumed to be linear and isotropic with hysteretic type damping.
If the pile is not an end-bearing pile, the model of the pile is assumed that the pile extends to the rigid layer with the same cross section, but different materials are reinforced concrete and soil respectively.

For example: concrete (7 including crack, spalling, corrosion etc.); steel (4 including corrosion and deformation etc.); timber (7 including shrinkage and splitting etc.); and other materials (3 including cracking, spalling, slitting etc.).
Such a selection is based on the fact that concrete is the most commonly used material in bridge structures; and there are 46 varieties of concrete materials used in bridge construction, constituting 40.7% of all material types.
Furthermore, cracking in concrete materials is one of the most common and significant types of defect in bridge structures because cracking causes, over time, serious surface deterioration and concrete spalling..
Types of deterioration for major bridge materials [8] Methodology Bridge elements exhibit different deterioration behaviour due to different material types and their surrounding environment [8].

CMOS fabricated acoustic waves based sensors typically surface acoustic waves (SAW) sensors are able to process the outputs which can produce the information about the ultra-sensitive mass loading, properties of the bound materials and the changes of viscoelastic effects.
It is important to note that vp is a material property, and that, as a result, the synchronous frequency is both determined by material selection and a design parameter.

Expression characteristics of the model as a full feature information, and can reflect the correlation between the characteristics and the processing characteristics, including the geometric properties of each feature type, attribute accuracy, material heat treatment, the relationship between the properties and technical parameters required attribute information.
Wherein the characteristic information includes the geometry and dimensions of the geometry, such as the surface shape, the mutual position between the surfaces, dimensions and tolerances; also known as non-geometric information is the information technology rough features, parts, materials, processing accuracy, surface roughness, heat treatment , surface treatment, and engagement with relations and the corresponding technical requirements, this information is necessary for the formulation process.
