Shanghai Tower - SOLD OUT

Presented by Dennis Poon



See who's coming!


About the Presentation: 

This presentation will discuss the unique structural design aspects of the recently-completed, 632M-tall Shanghai Tower which has become the world’s second tallest building and the tallest building in China.

An innovative “Core-Outrigger-Mega Frame” lateral system was adopted to meet stringent Chinese code requirements for lateral stiffness and member capacities and to realize the iconic architectural profile efficiently.  An advanced Performance Based Design (PBD) approach was used to verify tower performance under various seismic-hazard levels through non-linear dynamic time-history analysis.

The continual lateral system optimization process that was applied through all design phases helped achieve a 20% wind load reduction through fine tuning of tower’s profile and a 13,000-ton steel savings through extensive optimization of the outrigger trusses and structural steel elements encased in super columns.  A 6M-thick, pile-supported mat foundation supports the tower and helps distribute loads more evenly to the soft supporting soil underneath with assistance from concrete fin walls at basement levels. End grouting was provided at tip of pile to increase pile capacity and reduce settlement.

About the Speaker: 

Dennis Poon, Vice Chairman at Thornton Tomasetti, has 39 years of experience in the design of supertall structures and mixed-use buildings worldwide. High on the list of his accomplishments is the role he played in leading the structural design teams for three of the tallest buildings in China: Wuhan Greenland Center (636m), Shanghai Tower (632m), and Ping An International Finance Center (600m), currently under construction. He was named one of the 25 Top Newsmakers of 2010 by Engineering News-Record magazine for his effort and contribution to supertall structure design.
