ss each. 1. A structural tee cut from w30 x 116 is designated as? a. WT15 X 116 b. WT30 X 58 c. WT15 X 58 Which statement does NOT hold true when comparing the ASD and LRFD Methods? 2. ASD is the traditional approach to design. The load factors in the LRFD Method varies depending on the load type. In the ASD Method, loads are summed without any factor. Using the ASD Method canresultinsain total steel tonnage on high-rise buildings. a. b. c. d. g an average of 5% of the What ASTM grade of structural steel is most commonly used for shapes other than W-shapes specified in commercial and industrial building construction in the United States? 3. a. A992 b. A7 . A36 d. A588Explanation / Answer
1. c. WT 15x58 as both height and weight get halved
2.d Using the ASD method can result in saving an average of 5% of total steel tonnage on high rise buildings does not hold true when comparing ASD and LRFD methods as LRFD is more realistic in terms of assessment of loads and material properties.
3.c. A-36 at present continues to be most commonly used structural steel for shapes other than W-shapes in commercial/industrial buildings. A992 is common for W shapes.A588 is weathering steel and popular for bridges etc
