1. - BEAM Sinusoidal Web Beam

2. WELDED PLATE GIRDER with CORRUGATED WEB WHAT IS A SIN-BEAM?
WEB: COLD ROLLED MATERIAL, COIL
Thickness: 1,5; 2,0; 2,5; 3,0 mm, Coil Width (= height): 1000, , 1500 mm , 500, 625, 750 mm (by splitting)
FLANGES: Hot Rolled Strip or Plate width mm Thickness mm

3. PRODUCTION PROGRAM WEB: COLD ROLLED MATERIAL, COIL
Thickness 1,5; 2,0; 2,5; 3,0 mm, Coil width (= section depth) 1000, 1250, 1500 mm
333, 500, 625, 750 mm (by splitting)

5. optimizing of welded profiles
THE MAIN PRINCIPLE
optimizing of welded profiles
BY INCREASING OF HEIGHT
UNTIL BUCKLING OF THE WEB
INCREASING THICKNESS OF WEB or
STIFFENING OF WEB
INCREASES
CAPACITY
OF THE BEAM
e.g PROFILING

6. IDEAL FOR DEEP LONG SPAN BEAMS SUBJECT TO HIGH MOMENT & LOW SHEAR
MAIN IDEA
TYPICAL BUILDINGS
SPANS OF 12-30m BEAM DEPTH GENERALLY BETWEEN
600mm TO 1500mm DEEP (INCLUDING A HAUNCH)
IDEAL FOR DEEP LONG SPAN BEAMS SUBJECT TO HIGH MOMENT & LOW SHEAR
Hot rolled
lattice
welded
Construction Weight
Fabrication
Transport
Site Assembly

20. Design of beams
Choice of height (Slenderness) SPAN – DEPTH RATIO – 15 TO 25
Choice of web thickness (Shear force) Vd = VED  VRd
Choice of flanges (Moment & Normal force)
