IMPLEMENTATION OF CONNECTION SYSTEM OF WOODEN PLATE AND WOODEN CLAMP ON JOINT MODEL OF BAMBOO TRUSS STRUCTURES

Abstract

The study of wooden plate bamboo connection system with the addition of wooden clamp was carried out taking into account the variety the angle of the stems at the joint. The loading was preceded through the application of compressive force at the joint’s member understudied up to reaching the maximum load and the connection was collapsed. It is known that the strength of bamboo not parallel to the direction of the fiber is lower than those parallel to fiber. Therefore, the strength of connection must be determined considering the strength of bamboo not parallel to the fiber direction. The experiment was carried out under static loading on the bamboo truss connections model with the various angle of connection stems of 0^o, 30^o and 45^o toward bamboo fiber direction. From the test result, it was found that there is a decrease in the connection strength at stem angle of 30^o and 45^o for about 16,80% and 12,21%, respectively, compared to the strength of the stem angle of 0^o. The test results also resulted the value of average elastic stiffness (S_e) of the connection also indicates a decrease in the of elastic stiffness value (S_e) of the connection for the stem’s angle 30^o and 45^o for about 42,62% and 82,95%, respectively, compared to stem angle of 0^o. It can be concluded that there is a decrease in the strength and stiffness of the joints along with the increase in stem’s angle of the bamboo truss connection system using wooden plate and clamp.
