Compressive Behavior of Rubber Wood Composite Short Column Fixed with Nails

Abstract

Assembly of processed rubber wood for use in civil engineering, there are many forms. Nail fastening is a form of fastening that gives the rubber wood that is bonded together stronger and can withstand higher strength. The primary objective of this research was to study the pattern of fastening of rubber wood with nails through the compression behavior of short columns assembled with rubber wood. The example of a short column has a cross section of 7.5 x 7.5 square centimeters. It consists of 3 pieces of
rubber wood with a cross section of 2.54 x 7.5 square centimeters and a height of 30 centimeters, which are fixed by nails in 4 different ways (number of nails and number of rows for fastening with nails). The test was conducted in the laboratory with the determination of physical properties and basic mechanical properties of rubber wood. Sample of the short assembly columns were tested by compression to determine the compressive strength and deformations of the columns until the failure occurred. The results showed that short columns could bear high axial compressive strength according to the number of nails used to fix
the columns, the maximum compressive strength was 24.32 kilo newton, and most of the sample column failures were crushed failures. The details will be discussed in this article
