MEC626 (F11) Assignment # 3 Solutions Prepared by Dr. J. Cao 4 Comments : The structure in the midterm is viewed as a truss, in which element #1 does not sustain any axial force and, thus, can be considered as “redundant”. Now, the structure is treated as a rigid frame, in which both axial and transverse effects are put into superposition. Element #1 still plays no role in its axial direction,

Unformatted text preview: which remains the same as in the midterm problem scenario. However, the externally applied weight acts as a shearing force for element #1, and element #1 now exhibits its role of “beam” to sustain that downward force and, accordingly, the bending moment. Therefore, element #1 becomes no longer “redundant”, as shown in its element force where neither the shearing force nor the bending moment is nil.
