How does the work of the fabricator differ from that of the erector? 5. Explain the designation W21 times 68. 6. How can you tell a shear connection from a moment connection? What is the role of each?
Solution
(4) Fabricator delivers the construction site steel components which are ready to be assembled, the received steel are assembled by the erector.
(5) wide-flange 21 in depth and 68 pounds.
(6) Shear connection – stops connection from sliding all directions. Resists the force to take it apart. Moment Connection – if pin or single bolt cannot move up or down but can rotate. One cannot rotate without rotating another. Moment connections used for overall rigidity of the building. Create structural continuity between the members. The shear connection is only to resist shear force only.
