Abstract.
Some conclusions will be very useful for the practical engineering application of the Metal Rubber material.
In practical engineering, the larger energy dissipation will be advantageous, but the larger effective shear stiffness should be in some limitation due to the requirement of the horizontal flexibility, so the selection of the H-W ratio of the MR vibration isolating bearing become an important issue in the structural seismic isolation design.

Abstract.
Some general issues related to LES in wind engineering are discussed also.
In wind engineering, the fluid around bluff build is major resource of pressure fluctuations; it should suffice to capture the largest turbulent structures in the wind field.
In this paper, some general issues related to LES in wind engineering are discussed and a typical horizontal large span cantilevered roof with grandstand is will computed with LES, the geometry and fluid parameters are same to reference of Lam[4], the fluid large scale structures are revealed.
In a realistic wind engineering application, the approach flow is fully developed turbulent boundary layer which contain wake effects due to upstream bodies.
