Which statement about load-bearing walls and framed structures is true?

• A. Load-bearing walls carry vertical loads themselves; framed structures transfer loads through columns and beams to foundations; walls are not main carriers in a frame.
• B. Load-bearing walls are nonstructural; framed structures rely entirely on timber.
• C. Load-bearing walls carry only horizontal loads; framed structures carry vertical loads.
• D. Load-bearing walls do not influence building stability; framed structures determine stability through walls.

Answer: (A)

The key idea is how vertical loads are carried in different construction systems. In traditional load-bearing construction, the walls themselves take the weight of the floors and roof and transfer it down to the foundation. In a framed structure, the load path runs through a skeleton of columns and beams; these members carry the vertical loads to the foundation, while walls mainly enclose the space and may contribute some lateral resistance but are not the primary vertical carriers. That’s why the statement describing walls as carrying vertical loads themselves and frames transferring loads through columns and beams to foundations is the best fit. The other statements mix up the roles—walls can be structural in some systems, framed structures aren’t defined by timber alone, horizontal loads aren’t the sole concern of walls, and walls can influence overall stability through their interaction with the frame.
