Abstract

Abstract The abundance of salam wood on the island of Java is an attraction for its use as a construction material. However, there is not much scientific information regarding the mechanical properties of salam wood. This study aims to identify some of the main mechanical properties of salam wood with destructive tests referring to ASTM D143 including tests for static bending, compression parallel to the grain, compression perpendicular to the grain, and shear, as well as physical properties of wood including density, specific gravity, and moisture content. Salam wood with small test samples free of defects in wet and air dry service conditions referring to SNI 7973:2013. The stress value generated in each test by air dry wood has a greater value than that of wet wood. In general, the wet service factor of the test results is not in accordance with the SNI value, but the static bending test for both MOE and MOR produces values that are close to the values required by SNI. Wet service conditions have a significant effect on the strength value of wood.

Abstract

The use of wood as a building material must be designed quite rigid and strong. According to SNI 7973:2013, the corrected design value on the wooden structure components must be in accordance with the condition of wood to be used. The objective of this study is to determine the value of timber beams stability (CL) both of softwood and hardwood based on SNI 7973:2013 for construction purposes. The material in this research to be used are pine (Pinus merkusii), agathis (Agathis dammara), mahagony (Swietenia macrophylla), and red meranti (Shorea leprosula). Testing of physical properties include moisture content, specific gravity, and density, meanwhile testing of mechanical properties include flexural strength, modulus of elasticity, and ductility. Mechanical testing is carried out on a small clear specimens and full-size specimens, while the physical properties are tested only on a small clear specimens. The full-size specimens are visually sorted and the strength ratio (S) is determined prior to mechanical testing. The result of this study showed that the highest strength ratio was in meranti 55.85%, agathis 52.98%, pine 46.76%, and mahogany 46.60%. Softwood has a lower S value to more knot defects than hardwood. The slenderness ratios of agathis, pine, mahogany, and meranti wood respectively are 7.48, 7.45, 7.40 and 7.66 so that all specimens are referred to as short beams. The value of beam stability (CL) is close to 1 that indicates that the beams are stable and does not twist.
