Perilaku Kuat Tekan dan Kuat Lentur Dinding Pasangan Batu Bata Dengan Perkuatan Diagonal Tulangan Bambu

摘要

When there is an earthquake, wall is part of most frequent damage. In high-rise buildings it has to be strengthen with crosswise steel reinforcement wall. For a one floor building walls which is not planned mostly, so the damage is severe enough, therefore diagonal reinforcement are needed to minimize the damage. Installation of the same reinforcement in the walls of high-rise building does not allow for a one floor building because it requires expensive cost and experts engineering, to solve the problem of steel reinforcement concrete it can be replaced with diagonal filled bamboo reinforcement because concrete and bamboo materials is better known with mostly people. This research is aimed to analyze the compressive strength and flexural strength of the walls without reinforcement and concrete walls reinforced with diagonal bamboo reinforcement. There is 4 pieces wall samples of each test with the size (100 x 50 x 12) cm with mortar ratio 1: 5, lightweight concrete mix design by trial and error. Braces diameter use size 4 mm with a distance of 15 cm and while the main reinforcement use 6 mm and concrete diagonal filled with bamboo type reinforcement lear maximum size is 8 mm. Analysis of the data by comparing the average results with each test performed wall. From the test results obtained concrete cylinders 1,709 gr / cm3 density and 5.83 MPa of compressive strength. Mortar compressive strength of the test gained 8.55 MPa. Testing of brick masonry walls without reinforcement diagonal values obtained an average 0.915 MPa of compressive strength whereas brick wall with diagonal reinforcement bamboo reinforcement values obtained an average 1,109 MPa of compressive strength. Testing of brick masonry walls without reinforcement diagonal values obtained average 2,670 MPa of flexural strength whereas brick wall with diagonal reinforcement bamboo reinforcement flexural strength values obtained an average of 3,260 MPa. From the data above it can be concluded the compressive strength and flexural strength of brick masonry walls with diagonal reinforcement bamboo reinforcement is greater than brick masonry walls without reinforcement.
