FIXED SADDLE BASEPLATE WELDING CALCULATION (BASED ON GOVERNING CASE - BLAST)
General DataBase Plate Thickness Tb = 40 mm
Base Plate Length L = 2950 mm
Base Plate Width Wb = 400 mm
Weld ( Base Plate )
Fillet weld joint efficiency = 0.55
Welding stress for steel grade43(E-43) = = 125 N/mm2
Allowable welding stress,fw = = 68.75 N/mm2
Condition
Vertical Load Wd = 2236680 N
Max Cumulative Shear Force Fh = 855479.0 N
Moment at Base Mot = 1591191000 Nmm
Cross Sectional Area of 1/2 Skirt, = pi() x (2R-t) x t x 4*a/360 A = 9803 mm^2
Stresses in Base Plate Weld
Weld leg for base plate w = 8 mm
Cross section of weld Aw = 53856 mm2
Section Modulus of weld Zw = 32899175 mm3
Shear stress ( max ), =Fh/(2*Aw) fsw = 7.9423 N/mm2
Bending stress ( max ) fbw = 48.3657 N/mm2
< fw, then OK Since fsw & fbw
