Using the Matrix Displacement for Rigid Frames. Create an excel file to solve for all the bar force members for the given truss.
Select all zero force members in this truss
1. Determine the force in all members of the truss using the method of joints 2. Determine the force in members DE,DB and AB using the method of sections To begin the analyse linear unknown forces a of the joints in Figure criteria. Therefore, we equations applied to the © = 0 M = 0 - 10 OXF, = 0 OK B 10 kip to 3 ft to 3 ft + 3 ft 3 ft . (a)
Indicate all zero-force members. Then. determine the force in members IC and IG of the truss and state if these members are in tension or compression. F AX: Fly Ay +E9-1-- A MOK EM -103)-1645). Ey(1) Ey = 7.5 kr -1.5m----15m 15 m tism 1.5 m-- Ey 6 KN KN AL
Determine the force in members JE and GF of the truss and state if thesemembers are in tension or compression. Also, indicate all zero-force members.
