Chapter from fib Bulletin No.92 - Serviceability Limit State of Concrete Structures

Serviceability limit states are essential for appropriate function and durability of concrete structures. The attention is paid especially to the stress limitation, crack width analysis and deflection analysis. The document provides supplementary information to the fib Model Code 2010 (MC2010), where a limited space did not allow for a detailed description of individual procedures. The principles used in MC2010 in chapter 7.6 are explained in detail within this document.

A simplified model based on the assumption that bond stresses are linearly distributed along the ...transmission length is here set up to study the cracking behaviour of an RC tie subjected to monotonic loading, taking into account the effects of the so-called Goto cracks, or internal secondary cracks.

A simplified model that takes account of the effects of the so-called Goto cracks, or internal se...condary cracks, is here set up to study the mechanical behaviour of a reinforced concrete tie subjected to monotonic loading, at the crack formation stage and the stabilized cracking stage.

A further extension of a general crack prediction model to the case of a concrete tie reinforced ...with two types of bars with different diameters and different bond characteristics, subjected to a statically applied axial force, is here presented.
