EXPEDIENT REINFORCEMENT FOR CONCRETE FOR USE IN SOUTHEAST ASIA. REPORT 1-PRELIMINARY TESTS OF BAMBOO

THIS REPORT SUMMARIZES THE PRELIMINARY RESULTS OF A CURRENT STUDY OF THE FEASIBILITY OF USING BAMBOO AS AN EXPEDIENT REINFORCEMENT FOR TEMPORARY, REINFORCED CONCRETE STRUCTURES. IT CONTAINS AN EXTENSIVE REVIEW OF THE LITERATURE, A DESCRIPTION OF THE TEST PROCEDURES, AND CONCLUSIONS AND TENTATIVE RECOMMENDATIONS FOR THE DESIGN OF BAMBOO-REINFORCED STRUCTURES. SOME OF THE PRINCIPAL CONCLUSIONS ARE: (1) ALTHOUGH BAMBOO HAS A FAIRLY HIGH TENSILE STRENGTH, ITS TENSILE MODULUS OF ELASTICITY IS RELATIVELY LOW (USUALLY LESS THAN 1/10 OF THAT OF CONVENTIONAL STEEL REINFORCEMENT) AND THIS LEADS TO LARGE DEFLECTIONS AND WIDE CRACKS WHEN BAMBOO-REINFORCED STRUCTURES ARE LOADED TO CAPACITY, AND (2) THE PRINCIPAL PROBLEMS ASSOCIATED WITH BAMBOO REINFORCEMENT, SUCH AS VOLUME CHANGES DUE TO MOISTURE VARIATIONS, LOW BOND STRENGTH, AND POSSIBLY DECAY, CAN BE MINIMIZED IF SPECIAL PRECAUTIONS ARE TAKEN IN PREPARING AND PLACING THE CULMS. BAMBOO-REINFORCED MEMBERS, DESIGNED AND CONSTRUCTED ACCORDING TO THE TENTATIVE RECOMMENDATIONS OUTLINED, CAN BE EXPECTED TO DEVELOP FROM TWO TO FOUR TIMES THE ULTIMATE FLEXURAL LOAD-CARRYING CAPACITY OF UNREINFORCED MEMBERS OF EQUAL DIMENSIONS. /AUTHOR/
