Solve the problem using the given method, provide complete solutions. STEEL DESIGN2.3 LOAD COMBINATIONSNSCP 2010 includes combinations for both allowable stress design (ASD) and load andThe number of combinations can be extensive, taking into consideration wind direction, «It is not unusual for computer printouts with 20 to 30 or even more load combinations toFortunately, not all structural members will be subjected to every type of load. Therefore,of the load combination formulas.Load Combinations for Allowable Strength DesignThe following are the basic load combinations used with ASD, as given in NSCP 2010 201) D+ F2) D+ H+ F+ L + T3) D+ H + F + (L, or R)4) D+ H + F + 0.75( L + T) + 0.75(L, or R)5) D+ H + F + (W or 0.7E)6) D+ H + F + 0.75(W or 0.7E)+0.75L + 0.75(L, or R)7) 0.6D + W + H8) 0.6D + 0.7E + HExample 2.1Calculating Load Using ASDThe loads on a steel beam consist of 150 kN due to dead load and 410 kN due to liveconsidered. Using ASD, calculate the required strength of the beam.Load Combinations for Load and Resistance Factor DesignThe following are the basic load combinations used with load and resistance factor design2010 203.3.1.1) 1.4(D + F)2) 1.2(D + F + T) + 1.6(L + H) + 0.5(L, or R)3) 1.2D + 1.6(L, or R) + (f¡L or 0.8W)4) 1.2D + 1.6W + fjL + 0.5(L, or R)5) 1.2D + 1.0E + fjL6) 0.9D + 1.6W + 1.6H7) 0.9D + 1.0E + 1.6HWhere:fi = 1.0 for floors in places of public assembly, for live loads in excess of 4.8 kPa,= 0.5 for other live loads 7. The axial loads for a building column have been computed according to the application building code, with thefollowing results: dead load = 200 kN; load from roof = 50 kN (roof live load); live load from floors (reduced asapplicable for large floor area and multi-story columns) = 250 kN; compression wind =126 kN; tensile wind = 104kN; compression earthquake = 60 kN; and tensile earthquake = 70 kN. Determine the critical design column load Pu,using the LRFD load combinations:Ans. Pu = 665 kN4
