In 2016, not a single building of 200 meters or higher was completed with an all-steel structural system. The significant use of concrete can be attributed to a combination of concrete’s relative ubiquity and lower cost in many regions, as well as its comparative simplicity in construction, which would increase its appeal in regions with lower-skilled labor pools. Concrete construction took the remaining share of completions with 58, or 45% of the total. Thus, this material trend is expected to continue to dominate, particularly as tall buildings continue to proliferate in seismically active regions like China, which mandate robust structural responses. ![]() ![]() Composite construction represents an effort to use the optimal properties of steel and concrete and counteract their respective weaknesses. ![]() The number of buildings completed in 2016 with composite structural systems hit an all-time high this year, with 68, or 53% of the total.
