Which of the following structural systems is most commonly used for high-rise residential buildings in urban Japan
Which of the following structural systems is most commonly used for high-rise residential buildings in urban Japan, due to its high stiffness and resistance to seismic loads?
A. Steel frame structure
B. Reinforced concrete (RC) moment frame
C. RC shear wall structure
D. Wooden frame structure
E. Steel-reinforced concrete (SRC) structure
Answer: E
Explanation: Steel-reinforced concrete (SRC) structures combine the strength of steel and the stiffness of concrete, making them ideal for high-rise buildings in Japan’s seismic zones. They provide excellent resistance to lateral seismic loads and are widely used in urban high-rise residential and commercial buildings, a key structural system in the exam.
