Tip

  • In polygonal walls meeting the H w / l w > 2.0 condition, the design shear force, V e , which will be taken as basis in calculating the transverse reinforcement in any section considered , is automatically calculated with Equation (7.16) .

Tip

  • Design Shear Force , V e for each point of each branch of polygonal walls , is automatically calculated according to the shear force diagram given in Figure 7.12 (c) .

Tip

  • The shear force dynamic magnification coefficient in Equation (7.16) is determined automatically. β v = 1.5 is taken as β v = 1.0 in buildings where all of the earthquake load is carried by reinforced concrete walls .

Tip

  • In all sections of polygonal walls with H w / l w ≤ 2.0, the condition that the design shear forces are taken equal to the shear forces calculated according to Section 4 is automatically applied.

 Design shear forces of polygonal walls with H w / l w ≤ 2.0 according to TBDY Article 7.6.6.3 are taken equal to shear forces calculated according to TBDY Section 4 . The shear force value calculated under the combined effect of the vertical loads and the earthquake loads increased with the Resistance Excess Coefficient D is used as the design shear force, V e . These shear forces are calculated in the center of gravity of the polygon walls and distributed to the polygon curtain arms in accordance with the shear force direction, taking into account the shear areas. This check is done for all loading combinations and the most unfavorable condition is taken into account.
