Foreword
The standard proposed by China Seismological Bureau.
This standard by the National Standardization Technical Committee earthquake (SAC/TC225) centralized.
This standard was drafted. Institute of Engineering Mechanics, China Earthquake Administration.
The main drafters. Zhang makes the heart, Sun Botao, Sun Jingjiang, Guoen Dong, Qi Lin are, Daijun Wu, Liujie Ping.
Introduction
This standard is in various domestic and international construction (structures) damage developed grading methods and criteria based on the results. Since the majority of configuration
Experience less damage buildings, destroy its research level partition method is not yet mature, this standard is currently only given two kinds of structures destroyed towers and chimney
Grading regulations.
Building (structure) building materials Classification of earthquake damage
1 Scope
This standard specifies the building (structure) building materials and methods of earthquake damage to the principles of classification.
This standard applies to the earthquake site damage survey, natural disaster damage assessment, intensity assessment, building (structure) building safety appraisal, and seismic damage prediction and
Engineering repair work.
2 Terms and definitions
The following terms and definitions apply to this standard.
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 Basic provisions
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.
