Structural Engineering Review

What are (3) things structures have in common?

• They occupy or take up space, they must be able to support a load without collapsing, they hold parts in desired positions

• They are made up of panels that form an enclosure, they are rigid members, they are built from block, stone, or concrete walls

• They are buildings in soft soil, they are large solid filled areas, they are wood or steel used to build a skeleton to frame a building

• They are poor design and engineering, they are material or connection failure, they are forces generated by people, vehicles, wind, earthquakes, water, etc.

What are the (2) major types of structures?

• Frame structures and shell structures

• Raft foundation and slab foundation

• Mass superstructure and bearing wall superstructure

• Tension and compression

Two major causes of structure failure are:

• Poor design and engineering, material or connection failure

• Static load and dynamic load

• Compression and tension, shear and torsion

• Steel, iron, and aluminum

What is the purpose of the foundation or substructure?

• To support the weight of the structure

• To keep the structure from sinking into the ground

• Both A and B

• None of the above

What are the (3) basic types of substructures?

• Raft foundation, slab foundation, and box foundation

• Basement, pile foundation, and buildings in soft soil

• Frame structures, shell structures, and mass superstructure

• Tension, compression, and shear

What is the part of the building that is above the ground?

• Substructure

• Foundation

• Superstructure

• Beam

What are the (3) basic types of superstructures?

• Mass superstructure, bearing wall superstructure, and framed superstructure

• Tension, compression, and shear

• Steel, iron, and aluminum

• Poor design and engineering, material or connection failure

What are the (5) different stress on a beam?

• Compression, tension, shear, torsion, and combination stress

• Static load and dynamic load

• Steel, iron, and aluminum

• Poor design and engineering, material or connection failure

When choosing a material for a beam, what are the four properties to consider?

• Strength, elasticity, hardness, and toughness

• Deflection, load, span, and weight of the load on the beam

• Steel, iron, and aluminum

• Poor design and engineering, material or connection failure

What is deflection?

• The distance the center of the beam moves up or down when put under a load

• The force or pressure that is put on a beam

• The distance between the columns that support the beam

• The ability of a material to not break under a force
