It should be noted that the positive influence of impurities on the strength characteristics (offset yield point s0.2, true stress at maximum load sm and in the fracture zone sf) in the transition from the coarse-grained to the submicrocrystalline structure is preserved (Table 1).

Kavyashree et al [4] carried out a time history analysis on two models having a regular plane and vertically irregular of 13-storey reinforced concrete buildings.
Yogesh et al [6] analysed a base-isolated ten-storey building.
The main objective of the present work is to evaluate the effectiveness of combining both infill panels and LRB on improving the nonlinear dynamic response of the building under the effect of a strong earthquake (El Centro, James RD 1979) [12].

A constant voltage of 5V has been applied to post-deposited Al electrical contacts on the VOx films and the respective current was measured as a function of temperature within the range 25-100ºC.
According to Smith et al. [24] at this thicknesses scale the V metal film is likely to be characterized by irregular metal islands rather than a continuous uniform film which is expected only at thicknesses above 10 nm.
