A36 Steel is the most extensively used structural steel material for construction purposes. This carbon steel material is designated by ASTM as ASTM A36 or A36 steel. Containing a maximum of 0.29% carbon, A36 steel is strong, ductile, formable, tough, and weldable. All these properties help A36 steel to be used for multipurpose applications. B Structural Steel and Steel Connectionsused in the design and constr uction of the WTC complex are shown in Figure B-2 for three ASTM-designation steels with minimum specified yield str engths of 36 ksi (A36), 50 ksi (A441), and 100 ksi (A514). In general, as the yield str ength of the steel incr eases, the

The plates can be easily handled and placed, thus allowing the procedure to be carried out relatively quickly, with minimal disruption to traffic. Chapter 2. Design of Beams Flexure and ShearChapter 2. Design of Beams Flexure and Shear 2.1 Section force-deformation response & Plastic Moment (Mp) A beam is a structural member that is subjected primarily to transverse loads and negligible axial loads. The transverse loads cause internal shear forces and bending moments in the beams as shown in Figure 1 below. w P V(x) M(x Design of Bolts in Shear-Bearing Connections per AISC Fn = Nominal shear strength, Fv = 0.50 Fu for bolts when threads are excluded from shear planes, i.e. A325-X or A490-X In addition, when a bolt carrying load passes through fillers or shims in a shear plane, the provisions of LRFD section J3.6 apply. Values of design shear strength for A325, A490, and A307 are listed in LRFD Table 7-10 7.

Recent static(l) and fatigue studies(2)(3) of composite members have indicated that the currently used design procoedure(4) for composite bridge beams is conservative~ The wide use of this type of con- LOAD AND RESISTANCE FACTOR DESIGN SPECIFICATIONLoad and Resistance Factor Design Specification for Structural Steel Buildings December 27, 1999 Supersedes the Load and Resistance Factor Design Specification for Structural Steel Buildings dated PROPERTIES OF WOOD AND STRUCTURAL WOOD MICROSTRUCTURE The primary structural building block of wood is the wood cell, or tra cheid. When closely packed, these wood cells form a strong composite system that is often compared to a bundle of drinking straws (Figure 3-1). As a unit, the straws (wood cells) weigh very little, but if restrained from
