Your columns have normal ductility level. Analysis settings are mixed (curtains are high, columns are normal ductile) or You may have chosen normal (walls and columns are normal ductile). Ash is applied on columns with high volumetric reinforcement ratio ductility level (I think you mean ash instead of ach). If you solve the structure with high ductility level, you can see the Ash values."bkrclk":vp0s6tm4" said:ash values why it says 0? If Idecad performs ach control, where can I choose the option.
You can check whether there is an A2-A3 irregularity in any floor in your building with the formulas given in Figure 2.2 and Figure 2.3 in the regulation."bkrclk":vp0s6tm4" said:How can I have A2 and A3 irregularity control done?
Hello again, A2 -Check if A3 irregularity exists or not. If there is A2-A3 irregularity in the structure, mark the A2-A3 irregularity in the irregularities section in the Floor parameters. Whether A2-A3 irregularity or not, when you apply semi-rigid diaphragm solution in the program, You will have the opportunity to make reinforcements taking into account the vertical and earthquake effects.You can check the floor bottom and top reinforcement area from the 3D model (in version 7, the reinforcements are given as As.) In order to solve the full rigid diaphragm, you need to verify that the earthquake loads are transferred safely in the critical areas of the floor. You can use the /A2-A3 regulation check."bkrclk":339ydw6w" said:thanks Mr. Hakan. I know how to do it according to the regulations but I asked how we can do it in the program. When I modeled a structure with a void ratio of more than 0.33 with idecad, it did not show any irregularity error.
When you apply a superstructure-foundation interactive solution, it is normal for the irregularity controls to be affected since the superstructure effects will be affected by the foundation displacements."bkrclk":3tjkoqoc" said:Another question I would like to ask is when I have the analysis done with a fixed connection without creating a foundation in the building model, irregularities appear, but when I add a raft foundation and have the analysis, the irregularity disappears in some floors. Does the program pretend to have a spring at the bottom while performing the fundamental analysis?
There is the phrase "Definition given in 3.3.4.1 for the length of each of the column wrapping zones". The phrase "Length" seems to be particularly emphasized. The length of the wrapping zone is mentioned. The volumetric reinforcement ratio is not mentioned."bkrclk":2gtgmw6r" said:thanks, Mr. Hakan, but the regulation says ash should be considered even if the ductility level is normal, as far as I understand from item 3.7.4.1. It needs to be taken into account.
