#### bridge a572 grade 50 steel with shear edges

### ASTM Structural Steel Standards Infra-Metals Co.

One of the most commonly used A572 grades is A572-50. This grade has an ultimate tensile strength of 65,300 psi and a high tensile yield strength of 50,000 psi. It is used in a broad array of structural applications, some of which include buildings, transmission CE 405:Design of Steel Structures Prof. Dr. A. Varma 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

= 58.0 ksi (for A36 steel) and 65.0 ksi (for A572 Grade 50 steel) (ref. Table 5.1, p. 273 of the textbook) Tensile failure Tensile failure is the result of failure of the material left to resist the applied load after deducting the void left by the bolt holes:A net = (b n x D) t where A Example Single Plate Shear ConnectionCE 434 Steel Design I Example Single Plate Shear Connection Use the simplified procedure for the conventional configuration of singleplate shear connections to check the adequacy of the following connection. Loads:PD 35 k PL 60 k Beam:Grade:A572, Gr. 50 Size:W27X94 Preferred Practices for Steel Bridge Design, Fabrication A 709 Grade 50S (bridge steel equivalent to A 992) is acceptable for painted rolled beam bridges and anywhere structural shapes are used in painted applications. Avoid using A 709 Grade 100 or 100W steel; Grade 100 steel has no real application for Texas because typical bridges are short- and medium-span bridges. Use A 709 Grade

The channel is bolted to a 3/8-in gusset plate with 7/8- in diameter, A307 bolts. The tension member is A572 Grade 50 steel and the gusset plate is A36. Assume the connection type is a bearing-type connection. a. Check all spacing and edge-distance requirements. b. Compute the design strength based on shear and bearing.

(B) Assuming That Block Shear Of The Tension Member Governs The Design Tensile Strength, Compute The Design Steel Cattle Guard - midland.tx.ussections using Grade 50 steel. The rail is welded to stringers (usually an 8 wide flange) and the finished cattle guards are cleaned and painted to the customer specifications. Big R Bridge also furnishes wing sections and pre-cast concrete bases for cattle guards. Greeley, Colorado Fort Worth, Texas Toll Free:(800) 234-0734 Phone:(970) 356-9600
