Abstract:
A completely changed design procedure for slabs was proposed in the February I970 ACI JOURNAL. In addition to providing a single design procedure applicable to all types of concrete slab systems reinforced in more than one direction, the revised Code contains major changes in the assumptions required to determine slab design moments by use of a frame analysis. This paper presents background for the equivalent frame analysis and gives an example of its application. In addition, moments calculated by the proposed frame analysis are compared with those measured in test slabs. Finally, tables giving frame design constants for common structures are presented in the Appendix.
