Studies on utilizing bamboo as structural and strengthening components are still limited. This paper presents a case study on effective and practical approaches for concrete-bamboo sandwich panels (CBSP) designed as load-bearing walls with two different wall thicknesses. Three (3) specimens for each type of wall were made to be the same height (1200mm) and width (600mm) and with a wall thickness of 150 mm versus 250 mm, respectively. The compression and moisture content properties of small clear bamboo materials made of Bambusa Vulgaris species were also measured. As a result, adding an 80 mm thickness of concrete to the wall has minimal impact on its ultimate strength. In fact, it has reduced the wall's compressive strength by 34%. Therefore, to increase the strength capacity of this bamboo load-bearing wall design, it is recommended to increase the number of round bamboo rather than the width of the wall.

摘要

Studies on utilizing bamboo as structural and strengthening components are still limited. This paper presents a case study on effective and practical approaches for concrete-bamboo sandwich panels (CBSP) designed as load-bearing walls with two different wall thicknesses. Three (3) specimens for each type of wall were made to be the same height (1200mm) and width (600mm) and with a wall thickness of 150 mm versus 250 mm, respectively. The compression and moisture content properties of small clear bamboo materials made of Bambusa Vulgaris species were also measured. As a result, adding an 80 mm thickness of concrete to the wall has minimal impact on its ultimate strength. In fact, it has reduced the wall's compressive strength by 34%. Therefore, to increase the strength capacity of this bamboo load-bearing wall design, it is recommended to increase the number of round bamboo rather than the width of the wall.
