Arup has participated in the project design since 2012, providing structural scheme and preliminary design consultation and review services at the construction drawing stage.
This large commercial complex is about 60 meters high, with 9 floors above the ground and 3 floors underground.

The long and narrow site and the stepped facade with staggered height increase the difficulty of adjusting the seismic design elements such as displacement and relative rotational stiffness.
This can minimize the structural cost and set aside more budget for building construction and green plant laying.
The architect hopes to expose all the frame columns at the peripheral bulges and the frame columns at the entrance of the atrium from the ground to the top, forming the architectural effect of the mountain tree terrace.
We once considered using less wall structure, but due to the limitations of the project’s own shape and wall location, the team finally chose the concrete frame structure to realize the design.
However, based on the comprehensive use of various factors such as function and demand, we analyze the weak position in detail and adopt targeted local strengthening measures to realize the structure without expansion joints, so as to reduce the impact on the building facade.
Through calculation and analysis, Arup team simulated the buckling mode of exposed frame columns to determine the effective length coefficient of exposed columns along the east-west direction, and optimized the size of shear connectors.

As one of the most creative architectural firms in the world, Heatherwick studio attaches great importance to the research and innovation of architectural functions and components.

The 45 ° inclined corrugated terrace is formed at the retreating building edge, the indoor and outdoor drainage of exposed columns, the difference of finish, and the 45 ° rotating structure pose a great challenge to the design of floor frame and maximum clearance space.
For example, the interior layout of shopping malls contains a series of irregular elements such as moving lines, atriums, activity spaces and large and small shops, which means that not all structural columns can adopt 9m column grid.
Relying on the rich business format and artistic atmosphere, the project provides a new one-stop retail leisure experience and becomes a new landmark of Suzhou Riverside life.
According to the conventional treatment method, the shrinkage problem of the floor will be solved by setting at least one expansion joint.
About 1000 fair faced concrete “flower pot columns” rise from the ground and extend from the ground to the top of the building to create a unique architectural style.
Tianan Qianshu is located on Moganshan Road, Putuo District, Shanghai, adjacent to Suzhou River in the north and M50 Art Industrial Park in the East.

In the narrowest 8th floor, the length and width are only 153 meters and 12 meters, and the plane length width ratio reaches 12:1.
The overall development is divided into two plots, East and West, with a total construction area of about 300000 square meters, built by the famous British designer Thomas Heatherwick.

In addition, the exposed column forms a 45 ° angle with the orthogonal bending moment beam grid, which makes the reinforcement at the beam column joint particularly dense..
However, the complexity of architectural form and construction brings many challenges to the project.
The eccentricity of frame beams and columns and the setting of shear connectors undoubtedly increase the design difficulty of building seismic performance.

The Tianan Qianshu project contains many components of different sizes, which is both a challenge and an incentive for structural engineering.
The building envelope retreats layer by layer, visually creating two mountains covered with green vegetation, just like the urban “Green Island” blending with the surrounding environment.
Therefore, we conduct local strengthening for single span truss, and use nonlinear time history analysis method to conduct detailed seismic response analysis and Simulation for unfavorable single span frame, so as to verify its strength and performance.
