Design Criteria for Horizontal Equipment 1. Wind Load: a). Basic diameter = diameter O.D. + 2 ( shell thickness + insulation). effective projected area = height x I.F. x basic diameter. b). Intensification Factor (I.F.): Diameter ≤ 760 mm, I.F. = 1.50 Diameter 900 to 1350 mm, I.F. = 1.40 Diameter 1370 to 1960 mm, I.F....

Square Foundation Design steps (with Moment) نوت: در صورت موجودیت مومنت عن المرکزیت (e)Eccentricity به وجود آمده و به اندازه (e) عمل قوه به سمت x و y انتقال (shift) می گردد. Step 1:- Calculation of loads = W T = W c + W F = W c + 10% W c Step 2:- Calculation of Foundation Area (A) = W T /p’ p’= Bearing capacity of...
