(一)前言竹材是一種價廉的建築材料,在我國的產量很豐富,它的抗拉强度很好,尤其是竹青部分可以達到很高的抗拉强度。幾年來,在我國的基本建設中,利用竹筋來代替鋼筋,為國家節約了相當數量的鋼材,但由於竹筋的防腐處理,竹筋與混凝士間的粘着力及竹材彈性模量較低等 (A) Introduction Bamboo is a cheap building materials, production in our country is very rich, its tensile strength is very good, especially bamboo green part of the high tensile strength can be achieved. In recent years, in our country’s capital construction, the use of bamboo instead of steel bars has saved a considerable amount of steel for the country. However, due to the anticorrosive treatment of bamboo bars, the adhesion between bamboo bars and concrete and the elastic modulus of bamboo Low
