c) Civil engineering structures are designed to sustain various types of loads and possible combinations of loads that could act on them during their lifetime. Accurate estimation of the magnitudes of these loads is a very important aspect of the structural analysis process. Discuss the following loads in the design and construction of steel structures: I. Impact loads II. Dead loads AP(5) d) A tension member consists of 150 x 75 x 10 simple unequal angles where whose ends are connected to gusset plates through the larger leg by a single row of four 22 mm holes in 24 mm holes at 60 mm centres. Use the method of section 2.3 to check the member for a design tension force of Nt,Ed= 340 kN, if the angle is S353 steel and has a gross area of 217 cm?.
