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

A. Longitudinal reinforcement:

Shear reinforcement :

Boundary zone width:

As per IS 13920-2016

hw/lw =21000/1500=14>2

Minimum net vertical reinforcement

slender wall= 0.0025+0.01375(300/1500) = 2363 mm2

minimum vertical reinforcement within boundary element table-1

1440 mm2 left ( 600mm width boundary element

1080 mm2 right ( 450 mm width boundary element

Minimum horizontal reinforcement in shear wall as per IS 13920-2016 table -1

ph= 750(300x1000)=0.0025, hw= 21000, lw= 1500, (ph)min = 0.0025+0.5(21/15-2)x0= 0.0025 which is same 750mm2/m

Maximum diameter of rebar for shear wall as per IS 13920-2016

1/10th of wall thickness =300/10=30mm

commercial rebar diameter 25mm shall be adopted

confining reinforcement spacing for boundary element as per IS 13920-2016 clause 10.4.4

maximum spacing confining reinforcement spacing for boundary element 150mm

sv=150mm, h= 1000 mm , Ash= 452 mm2.
