This paper provides an overview of serviceability specifications given by the fib Model Code for Concrete Structures 2010 (fib MC2010 [1]). First, the reasons behind crack control and deflection control are discussed, then specific design rules are provided. Simple rules as well as detailed models are also presented. Numerical examples are provided in order to assist in the application of the design...
The tension stiffening effect of chemically prestressed concrete (CPC) under uniaxial tension was experimentally investigated and compared with those of reinforced concrete (RC). A special specimen profile was designed to avoid the effect from end parts. The tension stiffening of both RC and CPC were compared with the current tension stiffening model. The crack pattern was observed after loading....
