The Study Bolted Joints Strength in Bamboo-Concrete Composite

Abstract

Bamboo ropes assembled in parallel and filled with mortar to create a composite structure. This study uses fixed loads and uses the EYM method. The purpose of this study is to investigate how connection strength, maximum load and stiffness values in normal weight concrete. The concrete design 25MPa used for threaded connections with diameters of 6 mm, 8 mm, and length of 40 cm. This study provides a maximum stress analysis of bolted joint strength and joint behavior. In this test, the study yielded a P-max value of 88.25kN at 6 mm diameter and a P min value of 16.87kN at 6 mm diameter for each variation of the sample. The P-Max value for 8 mm diameter is 29.71kN and the P-Min value for 8 mm diameter is 10.1kN. The stiffness values for each variant with a K-Max value of 41.53kN for diameter six and a K-Min value of 0.96kN for diameter six are 1.98kN K-Max value and 1.98kN K-Min value for diameter 8 mm, 0.21kN for diameter eight. The lateral resistance gives the same result of 8.8kN as for the ones melting point model. The maximum value of the pivot strength at 6 mm diameter and 40% load is 41.53kN/mm2. The highest value of the 40% load test with a diameter of 8 mm is 1.98kN/mm2. Two angle variations used in the test: 45° and 60°. The angular change of the sample damaged during the test was 60°, and the sample damage was 8 mm in diameter.
