Numerical Modeling and Parametric Assessment of Log Shear Walls with Bonded Corners

ABSTRACT

The paper investigates the stiffness and strength of log walls with standard and dovetail bonded corners under lateral loads. The finite element model is developed and validated with experimental work at small-scale and wall-scale levels. The validated wall-scale model was modified by conducting a detailed investigation on assessing the wall behaviour with varying crucial parameters, including coefficient of friction, vertical load, geometric irregularities, and the wall’s aspect ratio. The study suggested various techniques for improving the wall’s lateral load resistance capacities and initial stiffness, employing steel and wood pins.
