1 General Provisions
1.0.1 This code is formulated with a view to ensure safety and usability, advanced technique, economy and rationality in glass curtain wall project.
1.0.2 This code is applicable to the design, fabrication, Construction, project acceptance, maintenance and repair of glass curtain wall project of civilian building in non-seismic design and seismic design with earthquake fortification intensity of 6, 7, 8 degree.
1.0.3 In normal serviceability state, glass curtain wall shall keep good working performance. The curtain wall with seismic design shall work normally under the action of earthquake occurred frequently; it shall still work normally after repair under the action of fortification intensity earthquake; the framework of glass curtain wall shall not separate and fall under the action of earthquake occurred infrequently.
1.0.4 Quality control in whole process shall be implemented during design, fabrication, and construction of glass curtain wall project.
1.0.5 The materials, design, fabrication, construction and acceptance, shall comply not only with the requirements stipulated in this code, but also those in the current relevant ones of the nation.
