Reinforcement Detailing of Beams from ETABS output

AIM:

Reson for failure of the middle along grid a possible wats to solve

PROCEDURE:

• Calcualte value of max shear force in any one of span as per IS 13920-2016
• Longitudinal reinforcement of the beam grid -3From ETABs (mm^2)

• Shorter reinforcement of beam at grid 3 from etabs (am2/100mm)

• Logitudenal reinforcement of beam at grid 3 from etabs(mm2)

• shear reinforcement of beam at grid 3 from etabs )xm2/100)

• SWAY AT RIGHT AND LEFT AS PER IS 13290

right

Mas=174kMm

Mas=174kMm

Mbh=293kNm

Lab=4.725m

Vub=46kN

vub=230kN

left

Mah=234kMm

Mbs=155kMm

Vd+1=70kn

Lab=4.725m

Vua=185kn

Vub=45kn

SWAY SHEAR

EXISTING SHEAR CAPACITY AS PER DRAWING (AS PER IS 456 2000)

Vus=0.875FyAsvd/Sv

Fy=415N/mm2

ASv=151mm2

d=450mm

sv=100mm

Vus=245kn

hence shear in drawing is ok as per is 456 2000

RESULT:

AS PER ALL THE ARE DONE
