DESIGN AND MODELING OF HARDWOOD BEAM LAMINATE USING CSC ORION AND SOLID WORKS
Abstract
The study was undertaken to design and model hardwood beam laminate using CSC Orion, and Soild works. Three species of hardwood namely: Iroko (Miicia excels), Obeche (Triplochinia scleroxylen) and Mahogany (Swietenia macrophylla) was used for the study. The design and modeling code used was Euro code 5.Apart from the computer aided design and modeling of the hardwood beam laminate, the failure mode of the selected species of hardwood was evaluated through three point bending strength test. Results obtained from the computer aided design and modeling of the hardwood beam laminate using CSC Orion and Solid works revealed that the bending moment of Iroko, Obeche and Mahogany ranged from 7.3kNm – 7.34kNm, bending strength ranged from 5.92N/mm2 – 6.23N/mm2 , bending stress ranged from 10.18N/mm2 - 10.34N/mm2 , bending strength ranged from 1.48N/mm2 – 1.54N/mm2 , bearing strength ranged from 0.88N/mm2 -0.92N/mm2 , shear stress ranged from 0.62N/mm2 -0.65N/mm2 , shear strength ranged from 1.56N/mm2 – 1.62N/mm2 . Serviceability limit state check for bending, bearing and shear using the three different design and modeling software were satisfied. Evaluation of the failure mode of the three hardwood beam laminate revealed that the hardwood beam laminate showed similar failure characteristics. Failure was flat-wise and was initiated at the bottom fiber which was propagated upward. It was concluded that the timber extract from Mahogany showed better structural properties than Iroko and Obeche.
