Abstract. Collapse of timber constructions can appear under the effect of load that exceeds the resistance of a carrying element or under the effect of a geometrical instability like buckling. In addition, loading can be constant or varying for example loads due to wind or earthquakes. The aim of this paper is to study the behaviour and the lifetime of columns in wood or based-wood material such as glulam (GL) or laminated veneer lumber (LVL) under repeated loading leading to buckling.

“…Molina J.C. [11] studied the effect of adhesive content and wood moisture on the fatigue properties of the glulam. Chaplain M. [12] studied the cyclic torsional damage theory of glulam beams through experiments and numerical simulations and pointed out that a larger load amplitude results in more significant torsional damage. Enam M. et al [13] evaluated the fatigue behaviors of the emerging Structural Composite Timber (SCL) bridge stringers (LVL and PSL).…”

Flexural Fatigue Behavior of Glulam Beams Connected with Steel Splints and Bolts

Glulam beams connected with steel splints and bolts (GBSBs) are subjected to cyclic reciprocating dynamic loads in practice, which eventually leads to damage accumulation and structure failure. In order to promote the development of GBSBs, an experimental study was carried out, and theoretical analysis of the fatigue behavior of GBSBs was conducted. Three static load test beams and six fatigue test beams were designed and fabricated, taking into account the different stress levels and fatigue limit loads. Theoretical analysis of the data, linear regression analysis, and electron microscopy analysis of the material were carried out. The test results show that the GBSBs have good fatigue properties and that fatigue damage mainly occurs near the loading point. As the number of load cycles increases, the mid-span deflection and strain of the beam increase by a significant amount, and linear degradation of the stiffness occurs. In addition, a linear regression analysis of the amplitude of the fatigue load and the fatigue life was carried out, resulting in a fatigue limit load of 0.5435 Fu.
