DESIGN OF COMPOSITE BEAMS -II. COMPOSITE BEAMS II. 22. INTRODUCTION. A steel concrete COMPOSITE beam consists of a steel beam , over which a reinforced concrete slab is cast with shear connectors, as explained in the previous chapter. Since COMPOSITE action reduces the beam depth, rolled steel sections themselves are found adequate frequently (for buildings) and built-up girders are generally unnecessary. The COMPOSITE beam can also be constructed with profiled sheeting with concrete topping, instead of cast-in place or precast reinforced concrete slab. The profiled sheets are of two types Trapezoidal profile Re-entrant profile (a) Trapezoidal profile (b) Re-entrant profile Fig. 1 Types of profile deck These two types are shown in Fig 1.
Fig. 5. Parallel beam grillage The primary or spine beams also achieve continuity by being used in pairs with one beam passing on either side of the columns. Shear is transferred into the columns by means of brackets. This ‘offset’ construction, where …
