What is the name for a structural member primarily carrying a tensile force in the direction parallel to its longitudinal axis?

Tension member or Tie member

Define the term 'structural engineering' in a concise way.

Structural engineering is a branch of engineering dealing with structural analysis and design, ensuring structures can safely support external loads.

What is the main purpose of a structure's framework?

To provide form and stability, and to resist stresses and strains.

What is the difference between 'dead loads' and 'live loads' in structural design?

Dead loads are the permanent, unchanging weight of the structure itself, while live loads are variable and temporary, representing the weight of occupants, furniture, or other movable objects. Signup and view all the answers

What is a 'wind load' in structural design?

Wind load is a transient force caused by wind pressure acting on a structure. It's a crucial consideration for ensuring stability and safety, especially in areas prone to high winds. Signup and view all the answers

What is a 'seismic load' in structural design?

Seismic load is a dynamic force caused by earthquakes. It's essential to consider in seismic areas to design structures that can withstand the vibrations and shaking caused by earthquakes. Signup and view all the answers

Dead loads typically consist of the weight of materials, fixtures, and equipment within a building, but not of the structure itself.
