New effective “coupled” structural system of seismic protection of the building
Категория: Стр. тех. и арх. | Новость от: Admin | 27-12-2005

A number of systems of active and semi-active seismic protection of buildings is known by the reduction of the level of seismic loads effected on them. They are divided into 4 groups, including also seismic insulation, adaptation, dissipation of energy and vibrations damping.

Quite a new variety of seismic protection of buildings as a “coupled system” was developed which is based on redistribution of forces between the building and rigid structure, assembled out of it.

Two patents for invention have been got for the variant of structural decision of this system of seismic protection.

One of the variants of structural decision of the “coupled system” of seismic protection was implemented for 5-storied residential building in Gyumri. By experimental and theoretical tests it was revealed that in given case seismic load on building was decreased by 3 times. In addition, besides such high effectively of the system of seismic protection, significant exploitation (available) area was obtained.

In comparison with the traditional methods of reinforcement, the new system was performed by industrialized methods. The results of the design of this system gave no doubt due to the lack of complex elements and simplification of the design scheme, as for traditional methods of reinforcement of buildings the results of their design were problematic because of the compound section of bearing elements consisting of the materials with different modulus of elasticity.
