2. Model General 6 Advanced Training The objective of this manual is to show a way of modelling a scaffolding (class 3) using Scia Engineer. In this manual a simple example is elaborated. The following scaffolding will be treated in this course: When entering the project, the following project data are chosen: Frame XYZ Project Level: Advanced Material: S235 National Code: EC-EN and the following functionalities: Non-linearity (+ all options for non linearity on the right hand side) Scaffolding
Materials 7 Scaffolding For the materials, S235 is generally used. However, floor boards and toeboards will be inserted as members. The average weight of these toeboards and floor boards differs from the weight of S235. That is why is chosen to insert an extra material in Scia Engineer, at which the weight will be adapted. This weight can be determined as shown below: FLOOR BOARDS A distinction is made between floor boards of 19cm and 32cm. For each of them an average weight is calculated: Name Weight Steel board 32/307 Steel board 32/257 Steel board 32/207 Steel board 32/157 Steel board 32/140 Steel board 32/109 Steel board 32/73 Steel board 19/307 Steel board 19/257 Steel board 19/207 Steel board 19/157 Steel board 19/109 [kg] Length [m] 23.2 3.07 7.56 19 2.57 7.39 15.7 2.07 7.58 [kg/m] Average 12.2 1.57 7.77 8.20 kg/m 10.8 1.4 7.71 10.4 1.09 9.54 7.2 0.73 9.86 18.2 3.07 5.93 15.5 2.57 6.03 12.7 2.07 6.14 6.18 kg/m 10 1.57 6.37 7 1.09 6.42 It is assumed that the floor boards have a thickness of 4 cm. The weights of the floor boards are: 8, 2 kg ρ = m = 640, 63 kg 0, 32m × 0, 04m m Floor boards 0.32m: 3 6, 18 kg ρ = m = 813, 16 kg 0, 19m × 0, 04m m Floor boards 0.19m: 3
