Builders of steel-framed high rises already see faster erection times than those using other materials because of steel’s inherent advantages during the fabrication, staging, and erection phases. But two recent innovations are poised to accelerate the pace of steel construction even further. The non-proprietary design concepts were developed by Magnusson Klemencic Associates (MKA), an international, award-winning structural and civil engineering firm headquartered in Seattle. In both cases, they achieve more efficient construction by replacing reinforced concrete with steel during the construction of high-rise buildings. The first, which is already being employed in several U.S. buildings, is a modular assembly of concrete-filled composite steel plate shear walls that makes it possible to build four floors in a week instead of the three to five days per floor typical of an all-concrete building core. Another innovation just entering the testing phase, uses an assembly of modular bays fabricated from steel plate spanning structural floor beams in lieu of reinforced concrete-on-metal deck. A raised floor system bearing on the steel plate provides the finished walking surface as well as a ready-made raceway for ductwork and cabling.
The webinar will be presented by MKA's Ron Klemencic, who conceived the ideas for these innovations and has employed them in projects around the
country. Joining him will be representatives from Schuff Steel, Brett Manning, SE, Vice President of Engineering, and David P. Wright, Director of Preconstruction, who will present the perspective of the erector who has constructed buildings that feature these designs.
Learning Objectives:
- Explain the background issues that led to development of these revolutionary design concepts.
- Describe the features of these designs and how they work, including their performance under fire conditions.
- Identify the differences between them and traditional core and floor system designs that contribute to time savings during construction.
- Utilize the knowledge gained to educate clients in the benefits of these designs, providing data on the potential reductions in schedule and the cost savings associated with them.
