The W36 x 135 beam shown carries service loads shown (excluding weight). It has been decided to add a 10-meter steel column at point B to eliminate excessive deflection. If the column being added is fixed at the bottom and pinned at the top, design the column that can withstand as support (Use a recommended value for K. Evaluate using LRFD and ASD). a. Use WT18 section b. Use W36 section c. Using the section at (b), determine the dimension of the base plate if the foundation dimension will be 1500mm x 1500mm. Pp = 88 kN PL = 163 kN Wp = 21 kN/m WL = 58 kN/m C B 6 m 12 m

SOLVE please Determine the design bending strength of ISLB 350 @ 486 N/m, considering the beam to be laterally supported. Assume factored design shear force will not exceed 0.6 times the design shear strength of the cross-section. If it is used as simply support beam of unsupported length 5 m then determine the factored distributed load the beam can carry. Use Fe410 grade steel For ISLB 350 @ 486 N/m, section properties are as follows: h = 350 mm; b= 165 mm; t₁ = 11.4 mm; t = 7.4 mm; R₁ = 16 mm; Izz = 13158.3 × 104 mm²; I = 631.9 × 10¹ mm²; Zpz = 851.11 × 10³ mm³; Zez = 751.9 x 10³ mm³
