A rigid-jointed portal frame, shown in the figure, consists of beam and columns of equal length L. The frame has a fixed support at one end and a roller support at the other end. The frame is subjected to a uniformly dis...

Consider the horizontal axis passing through the centroid of the steel beam cross-section shown in the figure. What is the shape factor (rounded off to one decimal place) for the cross-section?

For the square steel beam cross-section shown in the figure, the shape factor about Z – Z axis is S and the plastic moment capacity is M_p. Consider yield stress f_y = 250 MPa and a = 100 mm. The values of S and M_p (rou...

A prismatic steel beam is shown in the figure. The plastic moment, M_p calculated for the collapse mechanism using static method and kinematic method is

A prismatic propped cantilever beam of span L and plastic moment capacity Mₚ is subjected to a concentrated load at its mid-span. If the collapse load of the beam is α Mₚ/L, the value of α is _________
