11.2.3. Bottom Column Moments

Try these first

1. 1.

   Define a column moment.

   Hint

   Think about the torque acting on the column.

2. 2.

   What is the design sign convention for positive moments?

   Hint

   Consider how moment values are categorized.

3. 3.

   What type of load is considered in bottom column moment calculations?

   • Horizontal loads
   • Vertical loads
   • Both

   Hint

   Think about the fundamental definitions of vertical loading.

4. 4.

   True or False: Shear forces always remain constant in a structure.

   • True
   • False

   Hint

   Consider how loads affect various structural components.

5. 5.

   Assess the moment on a fixed column experiencing both a distributed vertical load of 20 kN/m over 4 m and a point load of 30 kN at the end.

   Hint

   Decompose the load effects before combining!

6. 6.

   Investigate how an increase in the number of floors in a building affects bottom moments in columns below.

   Hint

   Reflect on how more parts equate to greater load distributions.
