ABSTRACT MANDANI, LESTER JOHN C., Department of Resource Engineering and Agricultural Mechanization, College of Engineering and Computer Studies, Pampanga State Agricultural University, Magalang, Pampanga. August 2022. "E ~ Bamboo Giant Bamboo - Dendrocalamus As: er : New Model of Wood Purlins". Adviser: Dr. Solomon L. Roque The study was conducted to produce and evaluate the performance of engineeredbamboo purlins with two different pattern design and adhesive. Four treatments were assigned as D:G:(T1) (LLLLL) and D2G;(T2) (LVLVL) using animal glue as the adhesive, D;G2(T3) (LLLLL) and D2G2(T4) (LVLVL) using pioneer wood glue and each treatment has three replications. The L layers represent the horizontal pattern, while the V layers represent the vertical pattern. This experimental investigation used a Randomized Complete Block Design (RCBD) with a 2-factorial Experiment with ANOVA, Multiple Comparison using Least Square Difference (LSD), and Pair Mean Comparison of Design. The giant bamboo (Dendrocalamus asper) with animal glue and pioneer wood glue are the raw materials that were used to produce the engineered bamboo purlins with a dimension of 2"x2"x4'. According to the findings, the engineered-bamboo purlins' flexural strength and compressive strength were inversely proportional. Also, the result revealed that the type of glue and layout design had significantly affected the physical and mechanical properties of purlins. According to the evaluation questionnaire, Treatment 3 with its LLLLL design and pioneer wood glue as the binder scored highest out of the four treatments. The engineered bamboo purlins' acceptance is as follows: T3 had the highest weighted average for smoothness (3.93), and a weighted average for overall appearance (4.2). Additionally, T3 has the lightest weight and is the easiest to nail in terms of handling and application, with a weighted average of 4 and 3.93, respectively. The engineered bamboo purlins' low cost is highlighted by the cost analysis. It only cost Php 149.48 per piece.
