3. Structural Design Features Of Buildings Flashcards
Accommodating the type and magnitude of the____ to which the structure will be subjected is the most critical aspect of engineering design.
Forces
Page 65
To calculate the structural supports needed to allow a building to withstand, common forces, _____are categorized and calculated.
Loads
Page 66
The direction of forces from loads acting on the interior of structural members is expressed as:
Stress
Page 66
The forces within a structural support system that resist applied loads are referred to as
Reactions R
Page66
Stresses within a material are classified according to:
The direction of the force
Page 68
Roads that are applied along the center of the cross-section, and may even reload the component.
Axial
Page 69
Loads that are applied to one side of the cross-section, and may bend the component.
Eccentric
Page 69
Loads that are applied at an angle to the cross section, and may twist the component.
Torsional
Page 69
When evaluating this type of load, an engineer can reasonably predict the constant force needed to be supported will equal to the weight of the object.
Static
-steady/applied gradually/dead loads are usually static
Page 71
This load produces highly localized forces and non-uniform loads in the supporting structural members.
Concentrated

The most significant force is generated by earthquakes.
2 part answer
Lateral loads that create horizontal motion
Page 76
In buildings with high variations or large floor plans, seismic______ can be added to increase the flexibility of the connection.
Expansion joints
Page 76
______absorb the resonant energy as the structure begins to move. These are typically installed at the connection between columns and beams, and operate on a principal similar mechanical door equipment that controls the movement of an automatic door.
Damping Mechanism

______isolates the building from the horizontal movement of the earths surface.
