12.1.2 fib Model Code for Concrete Structures 2010

The fib Model Code for Concrete Structures 2010 [44] describesthe following normal weight concrete classes:C12,C16,C20,C25,C30,C35,C40,C45,C50,C55,C60,C70,C80,C90,C100,C110, andC120,Next to the normal weight concrete classes, the fib Model Code for ConcreteStructures 2010 describes the following lightweight concrete classes:LC8,LC12,LC16,LC20,LC25,LC30,LC35,LC40,LC45,LC50,LC55,LC60,LC70, andLC80.

DIANA derives the following basic properties for these concrete classes:Young's modulus E,Mode-I fracture energy G_f^I.

fib Model Code for Concrete Structures 2010 also gives values for the mass density, thermalexpansion coefficient of reinforced concrete and limit values for thePoisson's ratio.DIANA presets the following material parametersfor a stress-strain diagram in the compressive and tensileregime [Fig.12.3].

Note that in DIANA the concrete property parameters are notreduced with a multiplication factor, in contrary to Paragraph 7.11.3`Safety formats for non-linear analysis' of the fib Model Code for ConcreteStructures 2010 [44], wheref_ctm = 0.85*0.70*f_ctm (compression).

If you specify the following input, then DIANA derives the materialproperties from the fib Model Code for Concrete Structures2010 regulations for normal weight concrete.

12.1.2.1 Plasticity and Cracking

The plasticity and cracking behaviour of the fib Model Code for ConcreteStructures 2010 is described by a Total Strain Rotating crack model[§6.2] with the fib Model Code for Concrete Structures 2010predefined tension softening function [Fig.6.4l] andthe fib Model Code for Concrete Structures 2010 predefined compression curve[Fig.6.5k].

Plasticity and cracking (syntax)

CRACKN

indicates that the cracking functions according to the fib Model Code forConcrete Structures 2010 will be used.

From this input DIANA derives the required properties for the crackingfunctions of the fib Model Code for Concrete Structures 2010, e.g.tensile strength f_t.

PLASTN

indicates that the plasticity functions according to the fib Model Code forConcrete Structures 2010 will be used.

From this input DIANA derives the required properties for the plasticityfunctions of the fib Model Code for Concrete Structures 2010, e.g.the compressive strength f_cfor the creep and shrinkage part. The element age and the notional size areused as the model code formulation indicates.

This example leads to the following sampling ages:0, 0.01, 0.03162, 0.1, 0.3162, 1.0, 3.162, 10, 31.62, 100.
