5.2 DESIGN OF SIMPLE BEAMS AND WELDED
CONNECTIONS
CLASSIFICATION OF STEEL BEAMS – EFFECTIVE SPAN –
DESIGN PRINCIPLES – MINIMUM THICKNESS OF WEB –
DESIGN STRENGTH IN BENDING / SHEAR –LIMITING
DEFLECTION OF BEAMS – LATERAL BUCKLING OF BEAMS
– MAXIMUM PERMITTED SLENDERNESS RATIO – PLASTIC
MOMENT OF RESISTANCE AND PLASTIC SECTION
MODULUS OF SECTIONS – SHAPE FACTOR – DESIGN OF
LATERALLY SUPPORTED SIMPLE BEAMS USING
SINGLE /DOUBLE ROLLED STEEL SECTIONS
( SYMMETRICAL CROSS SECTIONS ONLY ) (BUILT – UP
BEAMS NOT INCLUDED ) . TYPES OF WELDS – SIZE,
EFFECTIVE AREA AND EFFECTIVE LENGTH OF FILLET
WELDS – REQUIREMENTS OF WELDS – STRESSES IN
WELDS – DESIGN STRENGTH OF FILLET / BUTT WELDS –
LAP AND BUTT JOINTS FOR PLATE SAND ANGLES –
PROBLEMS ON DESIGN OF WELDED CONNECTIONS FOR
PLATES AND ANGLES ( MOMENT RESISTANT
CONNECTIONS NOT INCLUDED
