Abstract

Non-linier compression stress-strain relationship was derived from experimental investigation of 144 small clear specimens of three Indonesian hardwood species, namely Acacia, Meranti and Kruing. Both compression parallel to the grain and compression perpendicular to the grain were tested. The stress-strain curve consists of linier-elastic line until proportional limit and bi-linier curve. Stress-strain curve parameters for compression parallel to the grain, such as elastic modulus, post-elastic modulus, proportional limit, ultimate stress and post-elastic strain limit were derived based on the specific gravity. And also stress-strain curve parameters for compression perpendicular to the grain, such as elastic modulus, post-elastic modulus and proportional limit were derived based on the specific gravity and the angle between stress direction and tangential axis direction. Compression strength perpendicular to the grain in tangential direction was found much lower than compression strength perpendicular to the grain in radial direction.

Abstract

Two models of acacia glulam wood exterior beam-column connections with angles and steel rod system under monotonic static loads were tested and analyzed. The variation of the specimen was number of rod and thickness of angles attached at the beam. The behavior of each model under static loading, maximum displacement, maximum moment, rotational stiffness and ductility were observed. M9B1 type connections have more flexible than M9B2 type connections. The behavior of connection was depened on number of bearing steel rods at the beam, wood quality and thickness of the angles.
