4.1.2. Characteristics

Try these first

1. 1.

   Define static forces.

   Hint

   Think about forces that do not change rapidly.

2. 2.

   What characteristic allows us to predict the behavior of structures under static loads?

   Hint

   Look for the term used to describe things that do not change.

3. 3.

   Static forces are characterized as:

   • Rapidly changing
   • Time-invariant
   • Dynamic

   Hint

   Think about which option reflects stability.

4. 4.

   True or False: In static analysis, inertial effects are always significant.

   • True
   • False

   Hint

   Recall the characteristics of static forces.

5. 5.

   A structural beam is subjected to a steady static load that weighs 5000 N. If the beam deforms by 0.01 meters, calculate the modulus of elasticity of the beam material if the beam's cross-sectional area is 0.1 m².

   Hint

   Assess how stress relates circumstantially to the provided values.

6. 6.

   Consider a tall building designed to withstand static forces but later subjected to dynamic stresses of an earthquake. Describe how the building's static design might fail during dynamic loading and propose a modification to improve resilience.

   Hint

   Consider modifications that accommodate both static and dynamic influences on the building.
