臺灣孟宗竹材構件結構行實驗研究

Experimental Study on Structural Behavior of Taiwan Moso Bamboo Members

竹構造建築在生態永續發展與適應氣候變化的主流思維下，具有高度優勢，值得國內推展；但國內對於此項推展所需的竹構材基本結構行為研究仍屬缺乏。有鑑於此，本文以台灣最常應用之孟宗竹材，針對其撓曲行為，以及做為軸壓構件時之挫屈行為來進行探討，以瞭解竹材外徑、壁厚、竹節間距對此兩者行為之影響。經由64 組試體試驗結果，本文建立以平均外徑來估算竹材構件極限彎矩與臨界挫屈應力之方式。本文探討結果為後續竹材結構研究之基礎，並提供實務應用參考。

Bamboo architecture has advantages of sustainable development and climate changing adaptability that is worth developing. However, there are few fundamental researches of structural bamboo in Taiwan. This paper presents an experimental investigation of bending and buckling behavior of Taiwan moso bamboo (Phyllostachys pubescens) that the diameter, thickness and internodal length of bamboo are changed with height. After a total of 64 specimens tested and analyzed, the estimation of ultimate bending moment and critical buckling stress for different diameter is available for designing use. The fundamental result would be the basis for further research and application.
