14.1.5. Considerations for Safety Provisions

Try these first

1. 1.

   What is reserve load in structural design?

   Hint

   What extra strength should be built into the load-bearing structure?

2. 2.

   Name one variable load that a structure must accommodate.

   Hint

   Think of loads that can change over time.

3. 3.

   What is a key reason for incorporating safety provisions in structural design?

   • To make structures heavier
   • To ensure structures meet aesthetic requirements
   • To limit the probability of failure

   Hint

   Think about why we create safety features in construction.

4. 4.

   True or False: Live loads are more predictable than dead loads.

   • True
   • False

   Hint

   Consider what types of loads change over time.

5. 5.

   Design a small bridge accounting for variability in both material strength and loads. What safety factors would you incorporate and why?

   Hint

   Think about material strengths and local environmental data.

6. 6.

   Given a scenario where a beam shows signs of deformation under load, evaluate the necessary actions to take from an engineering perspective.

   Hint

   Consider the implications of deformation in a structural context.
