REINFORCEMENT DETAILS OF 7 SPAN CONTINOUS BEAM ALONG X AXIS

Beam no	Top rebar	Bottom rebar	SHEAR link
B29,B28,B27,B30,B31,B78,B79	3#25MM@100MM	3#20MM@100MM	8MM@100MM	FROM COLUMN FACE TO 2D
B31, B30 ,B78,B79		3#20MM@100	8MM@150	MIDDLE OF COLUMN
B28,B32		3#25MM@100MM

3 span continous beam along grid A

here the shear fore is high.

This failure beam no is B34

bottom longitudinal barr should be 50% of top longitudinal rebar as per clause 1s 13920 6.2.3

BEAM NO	TOP REBAR	BOTTOM STEEL	LINK
B33,B38,	TWO LAYER 3#20MM	3#20	TWO LEGGED 8MM@100

shear force in any span.

maximum shear V2 = 103.0079

moment Mh=80.30

moment Ms= 86.133

Clear span=5.3750

V1=103.0079 -(80+86.13)/5.375 = 72.
