Preparation Instructions
This specification is prepared by the China Academy of Building Research in conjunction with relevant units in accordance with the requirements of the State Planning Commission's Document No. 305 [1984]. This specification is a combination and revision of the Ministry's standards "Interim Provisions on the Design and Construction of Lifting Slab Building Structures" (JGJ8 (I)-76) and "Supplementary Provisions on the Design and Construction of Lifting Slab Building Structures" (JGJ8 (II)-79), absorbing the design and construction practice experience and scientific research results of the past decade, and adding the design, calculation and construction of multi-ribbed slabs and lattice beam slabs, the design and construction of basin-type lifting slab method, the construction of cast-in-place columns and tool columns, and the construction of walls and cylinders. During the preparation process, the opinions of relevant units across the country were widely solicited in various ways, and the revisions were made repeatedly. Finally, the Ministry of Construction and relevant departments reviewed and finalized the draft.
This specification is divided into twelve chapters and eleven appendices. There are six chapters in the design part, four chapters in the construction part, and one chapter in the acceptance part. The contents of these three parts are closely related. Its main contents include: general provisions, basic provisions for design calculation and construction, design and construction of structures such as slabs, columns, slab-column joints, and lateral force resistance, and quality standards and acceptance of slab-lifting structure engineering.
In order to improve the quality of the specification, please pay attention to summarizing experience and accumulating information in the process of implementing this specification, and send relevant opinions and suggestions to the Structure Institute of China Academy of Building Research at any time for reference in future revisions.
