CHAPTER 2 "MODELLING" 86 5.1.2 Wall filling With this command you can enter the wall fillings of your construction according to the provisions of the CEE: CANC. §2.1.4.2: - They are considered only for seismic actions. - They are mandatory when they adversely affect the operator. CAN §5.4.3c: It is forbidden to place the wall fillings selectively, on certain floors or positions of the building, and not in their entirety, so that the morphology is transformed from non-normal to normal. CAN. §5.9.2: In elastic analyses it is allowed to be considered in a crosswise arrangement (i.e. one diagonal is compressed and the other is flexed), giving each diagonal half of the stiffness EAR. In the inelastic analyses a pair of cross diagonals with full strain EAR each is used, but is only considered where it operates under compression. The simulation is performed with two diagonal bars with zero specific weight (since the loads of the wall fillings have been given as linear loads on the members of the beams) and with a surface area of dimensions according to the provisions of the CEE. The wall fillings are inserted with cross bars with the following properties: - Members' freedoms : Torque joints Mx,My,Mz, - Inert Elements: - A: Diagonal area Ar , which depending the type of analysis, is obtained: - Elastic Analysis : Taken Art/2, - Pushover Analysis : Each step of the analysis is done in 2 stages, in 1 o the pushover bars are identified, and in 2 o the analysis is repeated ignoring the first ones from the model, - E: Modulus of elasticity of wall infill = 800÷1000 x fwc,s , fwc,s: Compressive strength in the diagonal direction (S.18)
