Structural plates with atmospher-ic corrosion resistance (weathering) characteristics can be obtained by speci-fying ASTM A588 grade 42, 46, or 50. However, the availability and cost effec-Modern Steel Construction / February 1999 ASTM A572 Steel Plate - A572 Grade 42, 50, 55, 60, 65 A572 is the standard specification for high-strength low alloy columbium-vanadium structural steel. Lists five chemical recipes and five different mechanical property ranges for plate products (grades 42, 50, 55, 60, and 65). Relatively wide chemical and property ranges. Grade 50 high volume.
Mechanical properties, for example, exhibit much better than A572-50 & A36 - tensile strength 65ksi & yield strength 65ksi. Hence, A992 wide flange beams (H beams) are generally replacing A572-50. Product description:Item:A992 W-beam (or H-beam). Technology:hot rolled. Surface treatment:black, galvanised or primed. Dimensions:HEA, HEB & HEM. CE 405:Design of Steel Structures - College of Example 3.1 A 5 x ½ bar of A572 Gr. 50 steel is used as a tension member. It is connected to a gusset plate with six 7/8 in. diameter bolts as shown in below. Assume that the effective net area Ae equals the actual net area An and compute the tensile design strength of the member. b b a a 5 x ½ in. bar Gusset plate 7/8 in. diameter bolt A572 Gr. 50 Solution Design and Strength Evaluation of Critical Gusset Plates The gusset plates were fabricated by SS490 (ASTM A572-Gr. 50) mild steel with a Youngs modulus of 200 GPa (29000 ksi), a Poissons ratio of 0.3, and a yield strength of 345 MPa (50 ksi). The dimensions of the representative gusset plates (L2) are presented in Fig. 3(b).
composition ofA572 steel used in current test program (as specied by the manufacturer) is tabulated in Table 1. The test coupons measured 609.6 mm in total length and the length of tapered section is 304.8 mm. The cross section of the reduced section is 9.53 9 12.7 mm. The conguration of a typical test coupon used in creep tests is shown in Fig. 2. EngineeringEngineering information and connections for the global community of engineers. Find engineering games, videos, jobs, disciplines, calculators and articles Material selection and product specification Steel material is supplied in two product forms flat products (steel plate and strip) and long products (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces.

Types of Bridges Based on Span, Materials, Structures There are various types of bridges classified based on span, materials, types of bridge structures, functions, utility and position etc. A bridge is structure which allows passage over an obstruction. The obstructions may be river, valley, rail route or road way WIDE FLANGE SHAPESbridges and other civil engineering works.
