PSEUDO-DYNAMIC EARTHQUAKE RESPONSE MODEL OF WOOD-FRAME WITH PLASTERED TYPHA (MINIMA) BALE MASONRY-INFILL

This study investigated the design and evaluation of strength property of typha strawbale wall cross section. Assumption were made on edge column acting as axially loaded members that can resist vertical members from the loads acting on the wall. Based on this, the objective of this work is to provide the average design thickness for the cement-plastered typha strawbale that can stiffen the wooden frame. Data on strength and deformation of the structure are the input for the analytical models. Pseudo-dynamic earthquake response tests was conducted on one quarter (¼) scale model in a low rise storey wooden frames stiffened with cement plastered strawbale masonry. The structure was idealized as a plane frame. The analysis utilized the hysteresis models for members' models as time-independent. The force-displacement relationship of the members' models was evaluated by the approximate method on the basis of the material properties and structural geometry. The finite element model was designed with straw bale infill panel to determine the hysteretic parameters, stiffness deterioration and strength degradation due to seismic forces
