Tip

  • The axial pressure force control calculated under the joint effect of vertical loads and earthquake loads is done automatically A c ≥ N dm / (0.35 f ck ).

Tip

  • It is controlled automatically that the ratio of polygon curtains to the thickness of the long side in the plan is at least six.

Tip

  • The control that the curtain thickness in the body area of ​​rectangular and U, L and T curtains is not less than 1/16 of the floor height and 250 mm is automatically checked and the user is warned.

Tip

  • If the curtain arm is held by a curtain in lateral direction from both ends, the curtain arm thickness will not be less than 1/20 of the floor height and 250 mm, its conditions are automatically controlled.

Tip

  • Equation (7.14) is automatically checked and the user is warned. If both are met, the thickness of the curtain will not be less than 1/20 of the height of the highest floor in the building and not less than 200 mm, and the user is warned in geometry control.

Tip

  • Equation (7.14) is applied at the ground floor level in buildings with very rigid reinforced concrete curtains around the basement floors, and at the level of the foundation top level in other buildings.

ICONS

A c = Gross cross-sectional area of ​​the column or curtain end zone
ΣA g= The sum of the cross-sectional areas of the
structural system elements operating as a curtain parallel to the earthquake direction considered at any floor ΣA p= Total of the plan areas of all floors of the building
E = Earthquake effect
f ctd= Concrete design tensile strength
f ck = characteristic cylinder compressive strength of concrete
G = constant load effect
N dm =The largest of the axial pressure forces calculated under the joint effect of vertical loads and earthquake loads (taking into account the live load reduction coefficients defined for live loads in TS 498)
Q= Live load effect
V t = Total earthquake load acting on the building according to Section 4 (base shear force)

Requirements for the control of 7.6.1.2 and 7.6.1.3 are given in the Curtain Arm Thickness line under the Group Wall Dimension and Reinforcement Conditions heading of the Preliminary Information report of the Curtain Group . The picture below shows an example of the Curtain Group Preliminary Information report.
