1. General Principles
1.0.1 This Code is designed to meet demands in building structure design and requirements of secure application and economic feasibility.
1.0.2 This Code is applicable to the building structure design.
1.0.3 This Code has been made in accordance with principles stated in Unified Standard for Reliability Design of Building Structures (GB 50068-2001).
1.0.4 Effects involved with the building structure design include direct effect (combination of loads) and indirect effect (including subbase deformation, concrete shrinkage, welding deformations, temperature fluctuation or effects caused by earthquakes). In this Code, only provisions on combination of loads are stated.
1.0.5 The design reference period adopted in this Code is 50 years.
1.0.6 Effects or combination of loads involved with the building structure design shall be in accordance with this Code as well as other current national provisions.
