I. INTRODUCTION TO STEEL BEAMS Flexural members (beams) are defined as members acted upon primarily by transverse loading, often gravity dead and live load effects. Thus, flexural members in a structure may also be referred to as: Girders - usually the most important beams, which are frequently at wide spacing. Joists - usually less important beams, which are closely spaced, frequently with truss-type webs. Purlins - roof beams spanning between trusses.

I. INTRODUCTION TO STEEL BEAMS Girts - horizontal wall beams serving principally to resist bending due to wind on the side of an industrial building, frequently supporting corrugated siding. Lintels - members supporting a wall over window or door openings. Stringers - longitudinal bridge beams spanning between floor beams.
