2.1

System to withstand vertical and lateral loads (wind and seismic loads) consisting mainly of members.

2.2

Do not bear the load of the system components, such as (frame structure, reinforced concrete column story factory building) enclosure wall, since the load-bearing walls, parapets, decorative

Equipment.

2.3

Built during the earthquake (structures) destruction of severity.

3.1 Construction (structures) type

3.1.1

Building types include. masonry buildings; bottom frame house; within the framework of the Housing; reinforced concrete frame structure; reinforced concrete shear

Wall (or barrel) structure; reinforced concrete frame - shear wall (or barrel) structure; steel frame; steel frame - supporting structure; brick column bent structure

Bent open house;; wooden houses; soil stone structure housing steel, reinforced concrete column bent structure plant; plant.

3.1.2

structure types include. chimneys, water towers.

3.2 Construction (structures) damage classification principles

The extent of damage to load-bearing member, taking into account the extent of the destruction of non-load-bearing member and the repair or loss of function of the degree of difficulty and high

As low as division principle.

3.3 Construction (structures) damage classification step

Follow these steps to divide the building (structure) building was destroyed rating.

a) will be built (structures) according to the structure type classification;

b) distinguish the building (structure) buildings bearing member and non-load-bearing member, respectively, of their assessment of the extent of damage;

c) each member of a comprehensive damage, ease of repair and loss of function of the degree of use of the structure, assessment building (structure) building materials break

Bad grades.

3.4 Construction (structures) damage classification basic standards

Level 3.4.1 I. largely intact.

3.4.2 II grade

minor damage.

Level 3.4.3 III. moderate damage.

Level 3.4.4 IV. severely damaged.
