ordinary Black Bolts, Design strength of High Strength Friction Grip bolts (HSFG), Pin
Connections, Simple Connections, Moment resistant connections, Beam to Beam connections,
Beam and Column splices, Semi rigid connections
UNIT 1 - INTRODUCTION
Why Structural Design Courses?
Anyone managing the construction process needs a basic understanding of the engineer’s
environment and the basic understanding of how a structure behaves. Constructors must be able
to address a number of technical questions at the project site including structural issues that
sometimes are not addressed by the design professionals. Since the safety of construction
workers as well as the strength and stability of structures during the construction phase is of
paramount importance, construction mangers need this knowledge.
Definition: Determination of overall proportions and dimensions of the supporting
framework and the selection of individual members.
Responsibility:The structural engineer, within the constraints imposed by the architect
(number of stories, floor plan,..) is responsible for structural design
Safety (the structure doesn’t fall down)
Serviceability (how well the structure performs in term of appearance and deflection)
Economy (an efficient use of materials and labor)
Several alternative designs should be prepared and their costs compared
