Lead Line Load Example A = 25 ton

1 line= 25 ton

Lead Line Load Example B = 25 ton

6 line= 4,167 ton ~ 5 ton

Load on structure A = 25 ton + 25 ton = 50 ton

Load on structure B = 25 ton + 5 ton = 30 ton

B. Angle effect to BLock Load

Analysis:

Load = 25 ton

Lead Line Load = 25 ton

6 line= 4,167 ton ~ 5 ton

Load Block C = Load x Factor α deg angle

Load Block C = 25 ton x 2 = 50 ton

Load on structure = Load + Lead Line Load

Lead Line Load = Load

Parts of Line at Load

.

Load Block D = Lead Line Load x Factor α deg angle

Load Block D = 5 ton x 1.87 = 9.35 ton

.

Load Block E = Lead Line Load x Factor α deg angle

Load Block E = 5 ton x 0.84 = 4.2 ton

.

Load Block F = Lead Line Load x Factor α deg angle

Load Block F = 5 ton x 1.41 = 7.05 ton
