Top and bottom cleats

21 Top and bottom cleats

(a) Choose size of seating cleat angles

(b) Calculate the number of bolts required in shear and bearing on the lower cleat, which is assumed to support the whole of the vertical loading

(c) Alternatively, calculate the weld size to suit maximum length available

(d) Check buckling strength of beam web

(e) Check bearing strength at the root of the beam web

(f) Check bearing strength of angle cleat (area of bearing x design strength)

(g) Check bearing strength of column due to bolt loads where appropriate.

Cleats StructuresSteel Work Cleats

(a) Choose cleat size, and calculate number and type of bolts

(b) Calculate force in the outermost bolts connecting the cleats to the beam web, from shear and eccentricity

(c) Check bolt strength in double shear on beam

(d) Check bearing stress on the beam web and cleats

(e) Calculate force in bolts connecting beam to column or beam

(f) Check bolts in single shear on column or beam

(g) Check bearing stress on cleats and column or beam

(h) Check shear stress in cleats

(i) Check reduced beam section for shear and moment if there is a notch. Note 1. Where maximum edge distances cannot be achieved the bolt strengths should be reduced proportionally. Note 2. Shear on bolt = \f(F,2+Fb2), where Fs = reaction R/2 and Fh = R x e/a; e and a are shown on Fig. 22.

Flexible End Plates

(a) Choose plate size and number of bolts

(b) Calculate force in bolts

(c) Check bolt strength in single shear

(d) Check bearing stress on plate and column or beam

(e) Check shear stress in plate across net area after deducting hole areas

(f) Check shear in beam web over the depth of the end plate

(g) Choose fillet weld size to suit double length of weld (deducting amount equal to fillet size at each end of the run)

(h) Check reduced beam section for shear if there is a notch.

Note. Where maximum edge distances cannot be achieved the bolt strengths should be reduced proportionally.
