SHANGHAI TOWER
INTRODUCTION
The tower is designed in the form of 9 cylindrical buildings which are stacked one over
the other.
The outer layer twists through 120 degree as it rises.
The building has twin layers of
transparent facade.
ARCHITECTURAL SALIENT FEATURES
STRUCTURAL SYSTEM
The building has been divided into 9 separate zones along its height which are separated by 8
strengthening floors in between.
Thornton Tomasetti, structural engineer, has designed a simple, safe and cost-effective structural system
that permitted the creation of an innovative architectural form.
COMPONENTS OF STRUCTURAL SYSTEM
Core Wall Inner Tube System
Outer Mega Frame System
Super column system.
Floor System
Foundation System adopted for the Tower
Core Wall Inner Tube System
The central core wall of the tower is not uniform throughout of its height instead it changes as one rises.
At the bottom of the building, the core wall inner tube consists of 9 cells which forms a 30 m×30 m
square. This shape goes up to zone 4 level.
Core wall between zone 4 and 5 and 6&7 is as below.
It even reduces to rectangle of 3 cells for the upper most part of the tube.
Outer Mega Frame System
8 super columns along with 4 corner columns
Radial trusses, and
Box belt trusses two-story-high
columns Radial trusses Box belt trusses
The super columns are composite structure with concrete-encased steel
vertical sections.
There are four paired super columns – two at each end of each ortho
normal axis
Encased steel sections in the super column are the key element to ensure
the proper performance of the connections and thus the performance of the
structure.
From the performance-based design analysis, Embedded steel elements in
super columns and core walls were found to be elastic
Composite Super Columns
Floor System
The floors are designed as a composite deck which have profiled steel sheets as the
permanent bottom formwork for the reinforced concrete slabs.
Foundation System Super-long bored piles have length larger than 50m and slenderness ratio more than 50
were used.
831 reinforced concrete bore piles
more than 61,000 cubic metres of concrete
