Composite Steel–Concrete Beam Design

Verification of a W-shape beam under AISC 360-22 LRFD

AISC 360-22ASCE 7-22LRFD MethodComposite Design

Problem Statement

A composite floor beam in a commercial office building (Grid Line B, Bay 3–4) must be designed to carry the specified gravity loads. The beam is a W-shape with a composite concrete slab poured on steel deck. Verify all LRFD limit states and determine the minimum number of shear connectors.

Given Data

SpanL = 9.5 m

Beam sectionW310 × 97

Beam Fy345 MPa

Concrete f'c30 MPa

Slab thickness120 mm

Deck height76 mm

Tributary width3.2 m

Dead load4.8 kPa

Live load3.6 kPa
