Section 4 Transverse Beams

401. Arrangements

Transverse beams are to be provided on every frame.

402. Proportion

The length of transverse beams is not to exceed, as far as possible 30 times the depth of trans- verse beams for strength deck beams and 40 times for superstructure deck beams, respectively.

403. Section modulus of transverse beams

The section modulus of transverse beams is not to be less than obtained from the following for- mula:

Ě Ņ LǾĨĮ ĊᾜᾨĪ (cm3)

where:

Ċ = Spacing of transverse beams (m)

h = Deck load specified in Sec 2 (kN/m2)

l = Horizontal distance from the inner edge of beam brackets to the longitudinal deck girder, or between the longitudinal deck girders (m)
