KAJIAN KAPASITAS LENTUR PLAT BETON BERTULANGAN BAMBU WULUNG POLOS (ALTERNATIF PENGGANTI TULANGAN BAJA PADA PLAT LANTAI)

Abstract

The increasing of population will lead to increased need for housing. Market demand for steel reinforcement as a basic material in the constructionof residential houses will go up automatically . In fact, as we know that the iron ore as the raw material of steel is limited in nature and can not beupdated . Hence, there is need for the study of materials that allow to substitute steel reinforcement , one of which is bamboo . This research examinedhow the ratio of flexural capacity of steel reinforced concrete plate and bamboo Wulung . This study uses an experimental laboratory and implementedin Materials Laboratory and Structures Laboratory , Faculty of Engineering , Sebelas Maret University. Reinforcement bamboo usedplain ( without notch ) and dimensions of 5.2 mm x 10 mm with an area equivalent diameter of 8 mm steel reinforcement to be used as a comparison. Specimens used in the form of 3 concrete plate with steel reinforcement and 3 concrete plate with bamboo reinforcement. Same specimen size ,which is 600 mm x 400 mm x 100 mm and tested with third-point loading method . Bending capacity test will be done when the specimen was28 days . From the test results obtained the mean value of flexural capacity of steel reinforced concrete plate is 0.5262 ton.m and from bambooWulung is 0.1678 ton.m.
