In the wall design with high ductility level, there  are various increments in addition to the shear forces calculated under the combined effect of vertical loads and seismic loads, as  stated in Section 7.6.6.3 of TBDY . Explanation of the parts of the report, whose example is shown below, which are related to Section 7.6.6.3 of TBDY , will be made.

Curtains in the lower region of H w / l w  > 2.0 and H w / 3

 Design shear force, V e , which will be taken as basis in calculating the transverse reinforcement in any section, for shear walls in the lower region of the height  H w / 3 in the  shear force diagram, which satisfies the condition  H w / l w  > 2.0 ,   is calculated by TBDY Equation 7.16 .

The shear force in this equation dynamic magnification factor  β v = 1/5 is taken. However, in buildings with reinforced concrete wall that moved the entire seismic loads  β v = 1.0 is taken.

Here (M p ) t means the moment capacity calculated by taking into account f ck , f yk and the strength increase of the steel in the base section of the wall, and (M p ) t ≤1.25 (M r ) t is  accepted. (M r ) t means the moment of carrying power calculated according to f cd and f yd at the base section of the curtain . This value is located in the province of Moment-curvature analysis performed on the curtain.

(M d ) t , vertical loads in load multiplied by the base section and earthquake loads curtain means under the influence of torque calculated partners. Here, the shear section is defined in the center of gravity in a way to provide the three-dimensional rigid body movement condition of the shear finite elements. The moment (M d ) at this center of gravity obtained from the pitch finite element results of the respective loading combination is used as t .

V d value is the shear force value calculated under the combined effect of vertical loads and earthquake loads multiplied by the load coefficients.

If the vertical loads with  TBDY Chapter 4  according 1.2D of shear forces calculated by the earthquake (spaces curtains) or 1.4D (curtains beamed bond) values obtained from the amplified solid (Ve-threshold) with Denli I 7.16  , calculated by V e  value of the small The shear force is used as the design shear force, V e .

Curtains in the upper region of H w / l w  > 2.0 and H w / 3

For  shear  walls meeting the condition H w / l w  > 2.0 and located in the upper region of the height  H w / 3 in the shear force diagram   ,  the linearized design shear force value shown in TBDY Figure 7.11c is used in addition to the control performed using  TBDY Equation 7.16 . In this graph, the shear force value to be used in the upper section of the wall is taken as half of the design shear force at the base of the curtain. H w / 3 The design shear force at the height of the curtain section and the shear force value at the top of the curtain are combined with a linear line and the design shear forces in other sections are found.

The design shear force V e value of the walls in the upper region of H w / 3 is found with the linearized graph described above. These cutting force values ​​can be seen in the design results.

In the report, in order to indicate the shear force generated by the application of TBDY Figure 7.12 (c) graph on the walls above H w / 3 , there is the text "Fig 7.12 Design Shear Force" on the line where the relevant curtain is located.

 Curtains with H w / l w ≤ 2.0

 Design shear forces in all sections of walls with  H w / l w  ≤ 2.0 are taken equal to the shear forces calculated according to TBDY Section 4 . The shear force value calculated under the combined effect of vertical loads and earthquake loads increased with the Resistance Excess Coefficient D is used as the design shear force, V e .

Since TBDY Equation 7.16 is not used in the design of H w / l w  ≤ 2.0 curtains, these sections are left blank in the report.
