From the architect. Learning from the bridges of the great water town of ZhuJiaJiao, or those from the delicate gardens in Suzhou, we decided to link both sides of the 50 meters wide river with a bent path. The bent axis responds to different access conditions and visually adapts to the surroundings. Our strategy of borrowing from local historical references and other variables of the site, together with the objective of revealing the structural performance of the bridge, will generate the final form of the project.

The load-span relation recommends the use of the metal truss. In order to resist the strong torsion stress associated with the support-less winding shape of the bridge, we activate structurally all the sides of its distorted volume. Both shores of the river have a contrasting character. This fact is emphasized via designing asymmetric constraints for the structure. The bridge has a simple support on the transversal ramp that faces the rapid and narrow street at the northern access. On the contrary, there is a stiff connection with the longitudinal ramp that connects to the slow and large southern square. The elevation of the bridge adapts itself to the resulting asymmetric diagram of bending momentum. Trying to minimize the amount of different steel sections, we design a pattern that becomes denser according to the diagram of shear stress.

As other samples from Chinese tradition, we understand that the bridge should provide for a dedicated space on the river, a room over the water, more than merely acting as an engineering device that solves a communication problem. The faces of both the roof and deck are covered with wooden skins. The contrast with the exposed steel profiles makes the structure appear lighter. Furthermore, the sloped ceiling serves as a large reflector for the artificial lighting that is embedded into the handrails. During the day as well, the inner surfaces will trap the glittering reflections of the sun on the water.

its like my concept for a culture !!!!!!!!!!!snake

Musy · March 28, 2010

it's great,especially the frame.

otis · August 09, 2009

looks like fun :)

Dariusz · August 06, 2009

well.. it says more to me than that horrible over the top bulky Zaha bridge.

ivy · August 03, 2009

neat! i'd love to walk thru this one!

Corb · July 30, 2009

This design chases its tail. The skewed and awkward form seems to be imposed, rather than arising in response to any site-specific constraints. This in turn demands a cumbersome structure to conteract the torsional forces that arise as a consequence of this form. The cumbersome structure is antithetical to the elegance of a "footbridge" so the steel is painted white to make it "light"...? Clad the top to evoke the Chinese notion of "Space on the Water" and call 'er done. It is form for form's sake, which is too bad.

The concept of "structural density" as an expression of the stresses is interesting and could have been further explored to yeild a more elegant and natural solution.

nonono · July 30, 2009

the river look better without it, disturbing... at least for now.

IP freely · July 30, 2009

Fantastic!

helen · July 30, 2009

im pretty sure this is more about the engineering than the "spaces" in which case i find it also very intriguing. obviously like 99% of projects built in china these days.. the city planning... could be much better.

mark · July 30, 2009

its a bit of a waste, pointless, too dominering of its landscape, no sense of scale

corto · July 30, 2009

it is more than a bridge...
but i am not sure if it has to be or not...

I think is too much! waste of steel and wood.

nindya · July 30, 2009

wonderful!!roof is an important element in asia coz we have annual heavy rain season.

tony · July 30, 2009 05:51 AM

but rain, doesn't really have load right? i think this was a bit heavy handed

Pedro · July 30, 2009

Borneo Sporenburg meets Lucerne. Quite interesting, well done!

public eye · July 30, 2009

I thought I was starting to hate diagrid structure. Well, I love this one.

Durban · July 30, 2009

Over-scaled, unelegant and chunky. Cool shape but i think they just ruined that section of the river.

zhailiang · August 09, 2009 04:25 PM

Yeah, I agree. And it seems not comfortable at all. Think of all the steps and cars, bicycles have to go across it...

Marian · July 30, 2009

Structure and design brought together in cool shape !!!!!!

jr · July 29, 2009

it looks better without the wood-roof

kris · July 29, 2009

It is vibrant, dynamic, surprising and mystic like Chinese snake.

tony · July 30, 2009 05:52 AM

yes, like a snake... ;(

LondonGator · July 29, 2009

Awesome! Love the palette and space you're creating. Looks great!

Leo · July 29, 2009

looks like a 70's redo...over the top indeed.

greg · July 29, 2009

a bite over the top, no ?

StructureHub Blog · July 29, 2009

Well done. Painting the framework white was risky, but certainly paid off; it accentuates the warmth of the wood roof about (as well as the roof's angular undulations), brightens the roomlike (rather than bridge-like) interior volume, and enhances it's own visual appeal as a dynamic skeletal framework. I just hope that rust spots are kept away over time, which should be difficult with all the nooks and crannies in that sort of structure.
