    Bamboo-reinforce concrete slabs subjected to concentrated loading
    (1984) Kamkam, James Ampong
    This thesis deals with an investigation into the effectiveness of bamboo as a substitute for steel in concrete reinforcement, with particular reference to slabs. After an extensive review of the available literature on pertinent work done by other investigators, the report gives an outline of the work in which the writer has been involved. It contains details about eleven bamboo-reinforced concrete two-way slabs which were manufactured and subjected to various conditions of loading. The variables were the grade of concrete, span/depth ratio, bamboo percentage and the treatment given to the bamboo reinforcement. In the eleven slabs tested, with bamboo percentages varying from 2.86 to 4.0, punching failure, whenever it occurred, always followed the full development of the flexural collapse mechanism and the punching load was always greater than the yield-line-theory load. There was therefore no sudden shear failure without warning. This indicates that, under certain conditions, bamboo splints may safely be used as substitutes for steel in slabs of this nature.
