Analysis & Design of RCC shear walls in the model using ETABS

Aim :

To design the shear wall of the model .

procedure:

Analysis the given model

then click the shear wall design button in the ribbon

take screen shot of vertical reinforcement, horizontal reinforcement and boundary elements.

Draw the reinforcement detailing of the model.

Classification of shear wall as per IS13920: 2016

Hw/Lw = 2100/1500 = 14>2 so the wall is slender wall

The menimum vertical reinforcement as 13920:2016 is

= 0.0025+0.01375 (300/1500)

= 2363

The menimum vertical reinforcement of boundary elements as 13920:2016 is

= 1440 mm^2 on left side( 600 mm width of the boundary elements)

= 1080 mm^2 on right side ( 450 mm width of the boundary elements)

The menimum Horizontal reinforcement of shear walls as 13920:2016 is

Ph = 750(300/1000) = 0.0025

Hw = 21000

Lw = 1500

(Ph)min = 0.0025+0.5(21/15-2)*0

(Ph)min = 0.0025

Minimum diameter of the rebar for shear wall as per IS 13920:2016

1/10 of the wall thickness

300/10 = 30mm

adopt 25mm dia rebar

Spacing

1)300/3 = 100 mm

2)6*25 = 150mm

3)150

assume 150mm spacing

Ash = 0.005 Sv h fck/fy

Sv = 150

fck = 25

fy = 500

Ash = 452mm^2
