TEMPERATURE-DEPENDENT MECHANICAL PERFORMANCE FOR COMPRESSIVE STRENGTHOF STRUCTURAL TIMBER SOURCE FROM LOCALLY AVAILABLE SPECIES

ABSTRACT temperature. The average compressive strengths at different temperatures are as design decisions in various applications, particularly those involving exposure to high content also exhibits considerable variation, from 13.57% for Ekki wood to 43.23% for from 42.2 N/mm² at 20°C to 32.7 N/mm² at 100°C, Afara wood ranges from 38.2 N/mm² Ekhimi wood. These findings have significant implications for material selection and and products.It is recommended that wood species be carefully selected and designed at 20°C to 25.5 N/mm² at 100°C, and Albizia wood ranges from 33.1 N/mm² at 20°C Ekhimi, Afara, and Albizia) under various temperature conditions. The results show for specific applications, taking into account their mechanical properties and behavior the effects of temperature on the mechanical properties of other wood species and to that all wood species exhibit a decrease in compressive strength with increasing ranging from 478 kg/m³ for Afara wood to 997 kg/m³ for Ekki wood. The moisture follows: Ekki wood ranges from 62.3 N/mm² at 20°C to 48.4 N/mm² at 100°C, Opepe This study investigates the mechanical properties of five wood species (Ekki, Opepe, wood ranges from 52.6 N/mm² at 20°C to 39.1 N/mm² at 100°C, Ekhimi wood ranges conditions to ensure the safety, durability, and performance of wood-based structures to 22.6 N/mm² at 100°C. The dry density of the wood species varies significantly, temperatures. In conclusion, the study highlights the importance of considering the mechanical properties and behavior of wood species under different temperature under different temperature conditions. Further research is also needed to investigate develop predictive models for wood behavior under various environmental conditions
