Scope

Main technical content: In order to standardize the design, fabrication, construction, and acceptance of prestressed concrete composite slabs with steel tube trusses, implement the national technical and economic policies, and ensure safety, applicability, economic durability, and quality, this standard is formulated. This document is applicable to areas with an earthquake resistance intensity of 8 and below, and industrial and civil buildings in environmental categories I and IIA in which prestressed concrete composite slabs with steel tube trusses are designed, fabricated, constructed, and accepted. The technology of prestressed concrete composite slabs with steel tube trusses shall comply with the principles of advanced technology, green aesthetics, and energy conservation and environmental protection. In addition to complying with the provisions of this standard, the design, fabrication, construction, and acceptance of prestressed concrete composite slabs with steel tube trusses shall also comply with the provisions of the relevant national standards currently in force. **Grouted steel-tube truss** is a structure composed of a grouted steel tube, two continuously bent flanges on both sides, and welded together with the prestressed concrete bottom plate reinforcement to form a steel tube composite truss, referred to as a steel tube truss. **Grouted steel-tube** is a composite structure composed of a hollow round steel tube or hollow elliptical steel tube and internal grouting materials. **Precast prestressed concrete panel with grouted steel pipe lattice girders** is a precast bottom plate formed by combining a steel tube truss with a prestressed concrete panel. **Prestressed concrete composite slab with grouted steel pipe lattice girders** is a floor slab formed by reinforcing a precast prestressed concrete panel with a grouted steel pipe lattice girder and pouring a concrete overlay on site. **Beard-shaped steel bars** are longitudinal reinforcin
