Excess reinforcement in basement column

[49emrah49]

hello, is it normal to use 10 16 gauge reinforcements in the 1st basement floor 30/60 column, while 36 16 gauge reinforcements are used in the 2nd basement? Can you help me. thank you.

Re: excess of reinforcement in the basement column Hello, In your project, in the 2nd basement floor, the pursantage values of all columns are higher than the other floors. One of the reasons for this is because it is a rigid basement floor, it works from the border with the existing reinforcements due to earthquake forces. By enlarging the cross-sections of the columns, you can reduce the pursantage. In addition, you need to enter a group curtain on the L-shaped curtain. I suggest you make a U-shaped core curtain design by combining the L-shaped curtain and the lower X-direction curtain in the Y direction.

Is it normal for the column to increase from 10 reinforcements to 34 (there is an effect of the column reinforcement being connected in the middle and being rigid, but isn't it abnormal for it to be this much). In most projects, the basement is already rigid. Also, there is no such thing when you solve it with a different package program.

There are both data errors and non-compliant situations in your system. Also, a more suitable carrier system installation should be considered. I write a few of them as an example; The edge is supported on the beams but there is no support in fact, they must be straightened or a carrier must be created 2) Basement perimeter curtains should be marked as basement curtain, if any, soil load should be entered according to TBDY2018 and a combination should be defined for these soil loads 3) L curtain (P1 and P3) group curtain and P3 curtain part should be marked as short curtain 4) Cassette flooring should be arranged according to TS500 item 11.5 ( - GEAR FLOOR WORKING IN TWO DIRECTIONS In accordance with the general principles given in LER Section 11.3, bidirectional gear floors can also be arranged. The principles of structural mechanics should be followed in the structural analysis of such floors, and the rules given in Article 11.3.3 should be followed in the sizing and reinforcement arrangements. ) 5) In my opinion, the ramp floor should be defined as a stair plate and should be supported by its 2 opposite short sides and should be solved together with the structure at appropriate thickness and load.
