1. What are the purposes of the various types of drawings used for the design and erection of
steel-framed buildings?
the design and erection of steel-framed buildings required various types of drawings include:
Design drawing: are prepared by a structural engineer. They indicate the type of construction and
give date in shears, leads, moments, and axial forces the must be resisted by each member and all
connections. Notes are used to give more additional information that allows a structural detailer
to prepare for various members. Contains the data needed by the steel fabricator.
Shop drawings: contain fabrication of each member, specifies size of the member and the exact
location of holes for connections.
Erection plans: are assembly drawings used on site to direct the placement of each member in its
desired location, also include details showings the anchor bolt locations in the foundation and
anchor bolts are used to secure columns to the foundation. Identifies each structural by a mark
and shows their locations.
2. how are structural steel members lifted for install-lation as the erection process proceeds?
The structural steel members are delivered on site to be constructed. The members are
placed near the point of their erection.
verifying the correct placement and elevation of the anchor bolts, an erection crew lifts the
first level of columns with a ground level crane and places them over the bolts cast in the
foundation, girders and beams are lifted using cranes are these are to secure to the columns
using required connections, after framing the floors, specified decking are installed
As the building rises beyond the reach of the ground a tower crane can be used to reach
upper levels, also a guy derrick can lift itself to floors constructed above it, and its
controlled using a power winch is located on the ground.
