Chapter 1 General 1.0.1 This code is prepared for the purpose of carrying out"The Law of Construction of People's Republic of China"and "The Law of Earthquake-prevention and Disaster Mitiga- tion of People's Republic of China",and carrying out the policy of giving priority to the prevention of earthquake disasters.Sothat,when the buildings are made earthquake-fortifi- cation,the damages to buildings,loss of life and economic losses will be mitigated. The seismic fortification objective of buildings,which designed and detailed in accor- dance with the requirements of this code,as follows: When the place is subjected to frequently earthquake influence which intensity is lower than the local fortification intensity,the buildings will not be damaged or only slightly dam- aged,with continued service without repair. When the place is subjected to local fortification intensity earthquake influence,the buildings will be damaged,with continued service after ordinary repair or without repair. When the place is subjected to rarely earthquake influence which intensity is expected to higher than the local fortification intensity,the buildings will notllapse nor suffer dam age that would endanger human lives. 1.0.2 Every building,which is situated on zones of fortification intensity 6 or above, must be designed to resist the effects of earthquake motions 1.0.3 The designof scmcordinary buildings and seismically islated structures,which are sit- uated on the zone of fortification intensity 6to9,shall be in accordance with this code. When buildings are situated on zone where the fortification intensity is greater than 9, andor industry buildings with specific professional requirements,the corresponding design of these buildings shall be in accordance with special provisions..

Chapter 2 Definitions and notations 2.1 Definitions 2.1.1 Seismic Fortification Intensity The seismic intensity approved by State authority,which is used as the basis for the seismic fortification of buildings in a certain region. 2.1.2 Seismic Fortification Criterion The rule for judging the seismic fortification requirements,which depends on the seis- micfneity and imranof the builings using functions. 2.1.3 Earthquake Action The structural dynamic action due to earthquake,including horizontal seismic action and vertical seismic action. 2.1.4 Design Parameters of Ground Motion The seismic acceleration time-history curve,the response spectrum of acceleration,and the peak value acceleration used in seismic design 2.1.5 Design Basic Acceleration of Ground Motion The design value of seismic acceleration,that exceeding probability is10%during the 50-years reference period. 2.1.6 Design Characteristic Period of Ground Motion The period value corresponding to the starting point of reduced section of seismic influ ence coefficient curve,which describes the earthquake magnitude,the distance of epicenter and the site-classes etc. 2.1.7 Site An area of a building group,usually it has similar characteristic in response spectrum. Its scope approximately equivalent to a factory area,a living quarter,a village or a plain area no less than 1.0km2 2.1.8 Seismic Concept Design of Buildings The process of making the general arrangement for the architectures and structures and of determining details,that based on the design fundamental principles and the ideas ob- tained from past experiences in earthquake disaster prevention and the constructional pro- ject. 2.1.9 Seismic Fortification Measures The seismic design contents except seismic action calculation and member resistance calculation,and details of seismic design included. 2.1.10 Details of Seismic Design 2
