Most Frequently Asked Questions 1) How should the interlocking joints of scaffolding systems be modeled with IdeCAD Static 8? The beams that make up the scaffold must be articulated so that they reflect the real behavior. For this, the freedoms to be considered in the freedoms section in the steel beam menu should be activated and major and minor M2 and M3s should be selected. In this way, the beams will not transfer moment. 2) While the scaffolding systems are modeled with IdeCAD Static 8, should its connection to the building be modeled? While scaffolding systems consist entirely of joints, they are fixed to the facade with simple joints in order to carry out the necessary work on the facade of the building. In order to create this situation in the program, 30 or 40 cm steel beams should be modeled as cantilevers in the direction of the building facade. Then, in order to reflect the behavior, a fixed support condition must be entered at the end of these cantilever beams that will correspond to the building. Or, it is modeled together with the entered reinforced concrete structure and connected to the columns, beams or shears of the building. If desired, a reinforced concrete curtain can be modeled at the height of the scaffolding and the scaffold may be connected to the reinforced concrete curtain instead of entering it with the reinforced concrete structure. 3) Since the scaffolding systems are not structural elements, should the earthquake effect be ignored? The earthquake effect is not taken into account in the design for scaffolding systems. In the annex published by the Ministry of Environment and Urbanization, there is an expression that the effects of wind loads should be taken into account along with fixed and live loads. Therefore, the design results should be analyzed according to the predicates g, q, Wx and Wy and their combinations. Combinations involving seismic loads should not be considered. For this reason, while examining the design results with IdeCAD Static 8, attention should be paid to the combinations in the design details. Earthquake combinations should be excluded from the design reports. 4) The beams I use in the pier do not meet the deflection requirement. Make the deflection limit of the beams that do not meet the deflection condition l/100 from the beam settings. Be sure to review the annex of the Ministry of Environment and Urbanization on Work Scaffolding and the TS EN regulations required to be used in this appendix regarding design principles.
