Bamboo scaffolding and Steel scaffolding

Hong Kong is a jungle of concrete and steel.But look closely,and you 'll see an organic materials that weaves itself through the cracks,up the walls,completely engulfing entire structures.

That material is bamboo.Hong Kong is one of the last places in the world where bamboo is still widely used as a building material.

Why is it used bamboo scaffolding in construction? For one,bamboo is sustainable and cheaper to source.Compared to steel, bamboo is also a light material.It is faster to put up and take down.If properly installed,bamboo can be stronger than steel and far more flexible.

But bamboo scaffolding is also dangerous and difficult to work with.Fewer and fewer professional scaffolders are engaged in bamboo scaffolding installation,which affects the safety of bamboo scaffolding.In most of mainland China,bamboo has fallen out of use as a construction material because of safety concerns.Builders favour aluminium and steel,which they consider to be higher quality.

Tianjin Wellmade Scaffold has rich experience in production of steel scaffolding.Offer different system scaffoldings to 55 countries,for example Ringlock system&#;Cuplock system&#;Kwikstage system&#;Frame system...Tianjin Wellmade Scaffold has passed CE&ISO certified and provide more durable products in competitive to customers.

I&#;m not an engineer, so I haven&#;t a clue whether it&#;s accurate or not, but the following sites make the claim:

USC - Architecture Department (warning: PDF) claims that Bambusa Tulda has been tested to a tensile strength of 52,000 PSI

It&#;s quite possible that these sites are incorrect, and to be fair, all sites claim that different varieties of bamboo differ greatly in tensile strength, but there are nevertheless a ton of sites making the claim.

That is one fascinating document!

For reference, a very basic carbon steel might have a tensile strength as low as 40,000 PSI. It&#;s yield strength would be somewhat lower than that.

The table 10.1 on page 28 gives a parallel-grain tensile strength of psi. Table 10.2 on the following page gives an ultimate tensile strength of psi, but it appears this was an assumption on the part of the source, who used an &#;allowable tensile stress&#; of psi. Only in table 10.3 is the claim of psi made, and I do wonder if someone accidentally slipped an extra zero in there. That said, bamboo is a fibrous material, and many natural fibres (e.g. spider silk) are impressively strong.

After hunting for a solid cite either way, I found this - a chapter from someone&#;s thesis researching this very subject.

Figures 4.1 and 4.2 show proper, reduced-section tensile test specimens not unlike the steel equivalents used for testing pipe. The results of their testing, given on page 91, state a range of 156-185 N/mm[sup]2[/sup], which converts to - psi. Which is impressive, certainly implies a greater strength weight for weight, and doesn&#;t rule out a stronger species of bamboo actually beating steel.
