and compressive strength acting on a series of simple specimens is not the main cause of damage
to the joined bamboo stems. Holes that are too big or too small also have a role in the damage to
the bamboo strung. Weakening due to improper perforation causes the friction force of the pegs
against the bamboo (in the holes) because it is loose so that the force acting on the pegs to bamboo
causes the bamboo to break, especially in joints with hard-made pegs such as metal. Whereas on
soft pegs such as wood and bamboo, more damage occurs to the pegs.
So, it can be said that the weakening of the joint is also influenced by the size and position of the
hole, the type of peg material. In structural elements that are dominant, the tensile force tends to
damage because the bamboo which functions as a tensile rod will result in a reduction in the area
of the tensile rod which affects the tensile strength where the distribution of the tensile load is not
evenly distributed but there is a right stress concentration on the edge of the hole of the one-way
connection tool. tensile force. This can be explained through the theory of elasticity (Suryoatmojo,
1997 in Gunawan 2013). An element that has a hole in the middle is loaded with a centric dance
load will cause an uneven load distribution (stress concentration occurs), right on the edge of the
large hole in the direction of tensile stress. An element that experiences a compressive force will
experience a bending force up to the maximum yield stress and buckling occurs because of the
instability of the compressive element.
In the model with a tie object, bamboo does not suffer significant damage, but the structural
structure of bamboo changes shape. This is due to the elastic-plastic binding material of bamboo.
4 CONCLUSION
The test results and exposure above concluded that the damage to the structure of bamboo is not
only determined by the size of the style, but also the related issue of the type of bamboo (the
physical properties of bamboo are arranged by the parallel fiber), layout connection, large hole
connection, the connection type, and the material of the tool connect.
It can be an input related to the creation of a means of connecting the new to further consider
physical form, the nature of the character of bamboo, and the laying of the tool connected. In
particular, a means of connecting based stake.
The idea that appears related to new connection tool is how to create a means of connecting
bamboo that is strong without damaging it, related to the bamboo physical form with fibers shaped
in parallel direction.
