A three member frame consists of a vertical member AB, 5m long and horizontal members BC and CD each 6m long, with C and D to the right of B. The frame is fixed at A and pinned at C and D. Member AB carries a load varying uniformly from 6kN/m at A to zero B which is acting to the right. Member BC has a concentrated vertical downward load of 40kN at 4m from B. Member BC carries a uniform downward load of 4kN-m. Determine the moments at A, B and C. Assume E to be constant and IAB =3I, IBC = 41 and ICD = 51. member df fem bj/Dist co bj/Dist co bj/Dist co bj/Dist FM

The beam is subjected to a service dead load of 2.5k/ft for the entire length and a service live load of 20 kips at 4 ft from left end. The self weight of the beam b = 12in h=24 in has to be added to the dead load for the calculations. How much is the reaction for the design load at point A and paint B?

Problem 5: Replace the loading by an equivalent resultant force and couple moment at point O. 0.5 m 0.7 m F,=(-2 i+5j-3 k) kN 0.8 m F = (8 i– 2 k} kN

A portal frame ABCD consists of columns AB and CD of heights 3 m and 4 m respectively. While the beam BC is of span 3 m. All the members have the same fully plastic moment Mp. The frame is subjected to a vertical point load of 40 kN at the centre of BC and a horizontal sway load of 18 kN at Cin the direction BC as shown in the figure. Find the fully plastic moment of the frame. Note that the given load system is the collapse load system. 40 kN 18 kN B N T.OS sto 3 mom amst.stameononselol 61ugler 3 mworle 4 m A
