Abstract

Abstract

For reinforced concrete beam- slab structures, the approximate formulas of temperature and shrinkage internal forces are introduced, and the formulas of critical internal forces of temperature and shrinkage, by which the overlong structural members can be judged, are deduced on the basis of the Code formula of cracking width. And for the overlong structures, the formulas of temperature and shrinkage reinforcements and some reinforcing measures are presented. All of these can be used as one of the effected ways and calculating basis for cracking resistance design of reinforced concrete beam-slab structures.
- overlong,
- crack,
- critical internal force,
- temperature and shrinkage reinforcements
