Extracted text: 1- A W 5300*101 of Steel Section (f= 345 MPa & fu= 450 MPa) is used as simply supported beam with a span of 15 m. The dead load is the summation of the super dead load (X1 kN/m as uniform load) and the beam weight. In addition to the dead load, a uniform live load is applied to the beam. If the lateral support is provided at 3-meter intervals, what is the maximum service live load in kN/m that can be supported.
