About the Project: 

Rising from the ground at a majestic 350 meters tall, Hanking Center Tower will become China’s tallest all-steel building upon completion. Halvorson and Partners worked closely with design architect Morphosis to create a visually stunning tower that slices the sky with striking assertion. An innovative architectural form, including a detached core and folded angled exterior, result in a breakthrough structural system. 

The core and core functions are located 10.5 meters from the main office floor plates. Sleek sky bridges connect the cores to these plates and allow full circulation. An all steel mega-braced tube’ connecting the two towers’ vertical planes comprises the tower’s main lateral system with secondary steel braced cores located around the escape stairs and mechanical areas to supplement the main bracing. The mega-braces connect the columns on four faces of the tower closing the tube structure and allowing the structure to efficiently carry typhoon level wind loads that are more than double those found in Chicago.



About the Presenters:

Eric Fenske, SE, PE 

Senior Associate

In his 12 years at Halvorson and Partners, Eric Fenske has served as a Senior Project Engineer for significant projects in all corners of the globe. The project types have included high rises, mixed-used developments and exhibition halls in the US, Russia, South Korea, Vietnam, and Australia.  In 2007, Eric took the reigns as Senior Project Engineer for UAE’s Central Market, a mixed-used development with three high-rise towers from 65 to 88 stories in height. He also served as Senior Project Engineer for an award-winning exhibition space in Shanghai, China with a sand dune-inspired design. His success in leading the project led to further developments in Yinchuan and Shenzhen, China, where he spearheaded the engineering of the Hanking Center, a 350 meter tower set to crown the skyline in 2015. Eric’s drive and abilities to innovate in the field led the Structural Engineers Association of Illinois to honor him as Outstanding Young Engineer, 2010. Eric continues to expand his project leadership efforts both internationally and in the US.
