Few Questions

[proisa]

First of all, greetings to everyone... I have some questions and I will need support on a few issues... 1. As it is known, in case of negative opening moment in the beams as a result of calculation, the assembly reinforcements remain in the tension region of the beam. However, the program puts either the statically necessary pursantage or 2Q12 anchors for mounting reinforcements, which can be lower than the TS 500 minimum beam tension zone reinforcement ratio. If the tensile zone is at the bottom of the beam, this ratio is automatically controlled. It'd better be checked in the case of negative torque as well. 2. When we want to have nonlinear static analysis, why do we need to get the loading states from the linear analysis section of the structure tree. If the loading conditions are not defined in the linear analysis section, we cannot define the loading conditions for the nonlinear analysis. In nonlinear analysis logically, shouldn't load cases be defined as child-nodes in the structure tree? 3. I wanted to add non-linear analysis loadings to the combinations in the template project. Since the template project was empty, I first added G, Q, EX, and EY loads to the linear load cases. Then I added nonlinear G, Q, EX and EY loads to the system using these load cases. Then I added the nonlinear 1.4G + 1.6Q, G+Q+EX, G+Q-EX, G+Q+EY, G+Q-EY combinations to the combinations. I drew an example system on this template and solved it. However, the program defined the G, Q, EX and EY states that I added earlier to the Non-Linear loading cases for the second time... And it calculated twice during the analysis... Should we define the loading cases and combinations that are not automatically defined separately for each project... Thank you in advance...

1. As it is known, in case of negative opening moment in beams as a result of calculation, the assembly reinforcements remain in the tension zone of the beam. However, the program also requires the installation reinforcements to be lower than the TS 500 minimum beam tension zone reinforcement ratio, either statically or statically. It puts anchorage or 2Q12. If the tensile zone is at the bottom of the beam, this ratio is automatically controlled. It should be checked also in case of negative moment.

This is in our notes.

2. When we want to have nonlinear static analysis, why do we need to get the loading states from the linear analysis section of the structure tree. If the loading conditions are not defined in the linear analysis section, we cannot define the loading conditions for the nonlinear analysis. Logically, shouldn't it be necessary to define loading conditions as child-nodes in the building tree in non-linear analysis?

The program uses the automatically generated loading conditions (g,q,ex, ey earthquake loadings, etc.) to make combinations according to TS500. ) takes. These loading conditions are also the loading conditions to be taken as basis for euler buckling analysis and/or nonlinear static analysis.

3. I wanted to add nonlinear analysis loadings to the combinations in the template project. Since the template project is empty, I first added G, Q, EX and EY loadings to the linear loading cases. Then using these loading cases, I wanted to add nonlinear G loadings. I added , Q, EX and EY loads to the system. Then I added nonlinear 1.4G + 1.6Q, G+Q+EX, G+Q-EX, G+Q+EY, G+Q-EY combinations to the combinations. Example on this template I drew and solved a system, but the program defined the non-linear loading cases G, Q, EX and EY for the second time that I added before... And it calculated twice during the analysis... Are the loading cases and combinations that are not automatically defined separately for each project? we need to define it....

In addition to the answer I gave to 2., as I wrote, the program automatically creates the predicate states such as G, Q, EX, EY, etc. that should be required by the regulation. You don't need to create. For the template project, it will be sufficient to use a project that has been analyzed once and create the loading combinations for the nonlinear analysis. Note : Nonlinear static analysis is currently not active.

Note : Non-linear static analysis is currently inactive.

So the program is not currently doing nonlinear analysis?

You may not be able to complete the analysis under any other load/load conditions.
