Religious belief plays an essential role for the style of houses and gardens in Bali Island, which is illustrated from 4 typical aspects as follows: Materials and colors.
Such natural materials as stone, wood, dry grass and clay are the most popular material for housing building.
Believing in all living things are god, residents in Bali choose to living in shelters made of natural materials to get close contact and communication with nature, or god.
In addition, original colors of materials as grass used in the roof, stone and soil in the wall and wood as the beam and column were mostly kept.

This calculation method does not fully consider the overall structure of work performance, and the impact of damping ratio of composite structure formed of different materials, Literatures[2-3] shows that: lattice shell's support conditions on the dynamic characteristics and seismic response have a major impact, therefore, reasonably calculate the seismic response of lattice shell structures must be considered the impact of the overall structure's work together and damping ratio of composite structure formed of different materials.
Lattice shell material parameters are as follows: The lattice shell's bar use Q235 steel, modulus of elasticity E=2.06×105Mpa, mass density ρ=7850kg/m3, poisson ratio 0.3; Independent column use C35 concrete, modulus of elasticity E=2.55×105Mpa, mass density ρ=2500kg/m3, poisson ratio 0.2.
(3)Damping ratio of the whole structure can not take 0.03 by experience, damping ratio calculation for this combination of different materials should be adopt test value of scale model or calculated value by equivalent structure theory method

But in fact, the acoustic attenuation of material is related with the ultrasound frequency’s square.
So the most common used frequency is between 10 - 100 MHz in practical inspection for material internal [5].
The scanning acoustic microscopy is based on the ultrasonic pulse reflection at the interface between materials.
