적용 범위

This standard is applicable to the seismic fortification of general construction projects in China, as well as the compilation of social and economic development plans. It is mandatory for general construction projects to meet the seismic fortification requirements specified in this standard. It provides the essential seismic ground motion parameters required for structural engineering and site selection.

기술 요구 사항

GB 18306-2015 establishes the technical elements and basic regulations for determining seismic ground motion parameters across China. It categorizes ground motion into four levels: basic ground motion, frequent ground motion, rare ground motion, and very rare ground motion, based on specific exceedance probabilities over a 50-year period. The standard specifies the determination methods for peak ground acceleration and the characteristic period of the acceleration response spectrum specifically for Class II sites. Engineers must use the provided zonation maps and detailed provincial tables to extract the correct parameters for their specific location. Furthermore, it outlines the adjustment procedures for other site classifications (I0, I1, III, and IV). The standard includes adjustment coefficients for peak ground acceleration and specific adjustment tables for the characteristic period, ensuring that site-specific conditions are accurately reflected in the seismic design parameters.

시험 방법

Instead of traditional material testing, this standard provides an evaluation methodology based on probabilistic seismic hazard analysis. It utilizes exceedance probability models to define ground motion levels. The primary evaluation procedure involves consulting the normative zonation maps (Appendix A and B) and the comprehensive provincial lookup tables (Appendix C) to determine the baseline parameters, followed by applying the prescribed adjustment factors for specific site classifications.

자주 묻는 질문

What products or projects are regulated under GB 18306-2015?

GB 18306-2015 regulates the seismic fortification of general construction projects in China. It is also essential for urban planning, disaster prevention, and environmental protection planning.

Is GB 18306-2015 a mandatory standard?

Yes, it is partially mandatory. Specific clauses regarding basic regulations, parameter determination for Class II sites, and the zonation maps in Appendices A, B, and C must be strictly followed.

How does this standard address different site conditions?

The standard provides baseline parameters for Class II sites. For other site types (I0, I1, III, IV), it includes specific adjustment coefficients and tables to modify the peak ground acceleration and characteristic period accordingly.

The summary above provides a high-level overview of GB 18306-2015.
