I was able to find these from another building. But in general, what I noticed is that they are done in a similar way.

Thanks for the reply. It may be a pin connection. My fear is that the axial forces coming to the shear wall will still occur in pin connections. On the problems that may be caused by these axial forces coming from the weak side of the shear wall. Additionally, the beams connected to the shear...

Thanks for the replies. In the second case, there is a problem: The beams are connected to the shear wall from many points. We like and want the beams to be connected to the shear wall through their strong axes. Because it is not good against forces coming along the weak direction of a shear...

In the first image, there are steel beams constantly connected to the shear wall. There are composite secondary beams between these beams.The loads of the secondary beams are taken by the steel beams located outside. The second image (taken from the real building) shows that the secondary beams...

When I put the composite beams between two steel beams connected to the shear wall as seen below, the P-M-M ratios of the steel beams are high. This is the example in the first picture. In the second picture: Connecting these beams to the walls creates the following problems. To connect steel...

Friends, the columns consist of concrete filling inside a 70mm steel profile. So it's not just concrete columns. Concrete filled composite columns. The building is a tall building over 200 meters. (It won't actually be done.)

Hello, I am designing a building with etabs. 150X150cm columns available. It has a floor height of 4 meters. Do you think I might be making a mistake by modeling these columns as rod elements?

As seen in the figure, there are 3 elevators. The width of the cavity is approximately 795cm ​​x 310cm. However, in the part you see with the yellow marked line on the left, the shear wall narrows and the gap becomes 815cm. My idea in this part is to adjust it with steel profiles and fit the...

Can elevator curtains be designed in different thicknesses in areas where elevator cabins are located in high-rise buildings? So, can elevator systems be designed according to varying curtain thicknesses? Have you actually encountered such a situation?

I do this at etabs. What I understand from what you said is to turn the composite deck into a concrete shell. Etabs automatically designs composite steel beams and composite floors. What I want to ask is that we do not use stiffness modifiers in linear analysis of steel elements. (excluding...

Hello, In linear analysis, I get the effective section stiffness of the composite floor made on steel trapezoidal sheet as follows. These values ​​are equal to the values ​​I got for reinforced concrete slabs. Are there recommended effective section stiffness values ​​for composite slabs? Do you...

Hello, I want to design Etabsta concrete filled composite column. I cannot add reinforcement when defining from normal composite sections. (version 22.1) Therefore, I want to design the composite column containing concrete-filled reinforcement from the section designer section (SD). However...

Hello, I want to design Etabsta concrete filled composite column. I cannot add reinforcement when defining from normal composite sections. (version 22.1) Therefore, I want to design the composite column containing concrete-filled reinforcement from the section designer section (SD). However...

To summarize the situation and simplify the question, let's first consider a building made of steel columns and beams and reinforced concrete walls. *First of all, when designing reinforced concrete walls, we apply the stiffness reductions given in the regulation. We do not make any stiffness...

Thank you for your answer. Yes, in our regulation, we use 0.8 like you to increase the displacements in steel elements. (Control and application of P-delta effects) However, the problem was actually this, in hybrid structures (steel + reinforced concrete), there is a decrease in the stiffness...

I will do nonlinear analysis for performance evaluation. However, I design with linear analysis for dimensioning the elements. (Required by the regulation) My question is about the stiffness modifiers we use in linear analysis. As you know, in this analysis, we assume that the reinforced...

How do you think I can adjust the stiffness modifiers when designing with linear analysis in hybrid structures where steel and reinforced concrete are used together? First of all, stiffness modifiers given according to certain earthquake ground movements in TBDY-2018 are used for reinforced...
