国产竹材试验资料证实,4～7年生的抗拉强度,竹节部份为700公斤/平方公分左右,节中部份为1300～1400公斤/平方公分;同济大学试验的竹皮抗拉强度达4000～6000公斤/平方公分,超出了钢筋的强度。近年来,竹筋混凝土在各方面研究试用有了很大进展,但尚未被应用在桥梁工程上。这无非是因为竹筋的弹性模量比钢筋低,活载的受力复杂,以及它的耐久性到底如何还没有得到很好的解决,故未敢冒进试用,这就阻碍了竹筋混凝土在桥梁工程上的应用和发展。目前国内正在研究变性竹材,已有初步成果,惟成本太高。况且竹材究属是有机物质,即使通过化学加工的变性竹材,是否可以永久不杇,值得怀疑;但是竹筋经过必要的一般防腐处理后,肯定会增加它的寿命。据上海解放日报载:“广
Domestic bamboo test data confirmed that 4 to 7 years of tensile strength, bamboo part of about 700 kg / cm ^ 2, part of the festival for 1300 ~ 1400 kg / cm ^; Tongji University tested bamboo skin tensile strength of up to 4000 ~ 6000 kg / cm, exceeding the strength of steel. In recent years, bamboo reinforced concrete in all aspects of research has made great progress, but has not been applied to bridge engineering. This is not only because the elastic modulus of bamboo tendon is lower than that of steel, the load of live load is complicated, and how its endurance has not been well solved yet Application and Development of Bridge Engineering. At present, China is studying the degeneration of bamboo, there are preliminary results, but the cost is too high. Moreover, bamboo belongs to organic matter. It is questionable whether the chemically modified denatured bamboo material can be permanently damaged. However, the bamboo tendon will surely increase its life after being subjected to the necessary general preservative treatment. According to Shanghai Jiefang Daily: "Canton
