Exam 4: Load Resistance the Structural Properties of Materials

In relation to its compressive strength, the tensile strength of concrete is

What is the difference between an I- section beam and an open- web I- section beam, called a castellated beam?

Explain the modulus of elasticity. Which property of the material does it represent? Give the approximate values of the modulus of elasticity of steel, concrete, and wood.

What is the difference between a ductile material and a brittle material?

The primary purpose of longitudinal steel bars in a reinforced concrete beam is to overcome the weakness of concrete in tension.

What does the term "strength" of a material imply and how does it differ from a material's ultimate stress?

The horizontal blocking in wood studs helps prevent

For most materials, their strength is directly related to their modulus of elasticity, i.e., the greater the strength of the material, the greater its modulus of elasticity. Is there a material whose modulus of elasticity is not related to its strength but is constant, i.e., it has a fixed value regardless of the material's strength? If so, name the material and provide its modulus of elasticity value.

In a suspension bridge, which member(s)is (are)in compression?

A material that is weak in tension is

Using sketches and notes, explain how we increase the bending efficiency of building components.

What is the yield stress of grade 60 reinforcing steel? Of A- 36 structural steel?

Which of the following beam cross sections is structurally more efficient in bending?

In a simple three- member truss consisting of two rafters and a tie, each member is in
