Zusatztext

Master's Thesis from the year 2016 in the subject Engineering - Civil Engineering, grade: B, Linnaeus University, course: Structural engineering, language: English, abstract: Imagine a world where sustainable construction meets unparalleled strength. This groundbreaking investigation delves into the innovative realm of glued laminated timber (GLT), pushing the boundaries of traditional timber engineering by exploring the synergistic combination of hardwood and softwood lamellae. Challenging conventional wisdom, this study meticulously examines how the strategic incorporation of hardwood, such as oak, can significantly enhance the structural performance of GLT beams. Readers will discover how the placement of hardwood within tension and compression zones, along with varying proportions, dramatically impacts stiffness, bending strength, and overall load-bearing capacity. Through rigorous experimental testing, including four-point bending tests and advanced optical deformation measurements, coupled with sophisticated finite element analysis, this research uncovers the hidden potential of combined glulam. Explore the dynamic modulus of elasticity, analyze section forces, and predict bending capacity with unprecedented accuracy. This comprehensive analysis not only provides valuable insights for timber engineers and architects but also paves the way for a new generation of sustainable, high-performance building materials. Uncover the secrets to optimizing GLT construction, mitigating failure risks, and unlocking the remarkable advantages of hardwood-softwood synergy. This essential resource bridges the gap between theory and practice, offering a roadmap for creating stronger, more resilient, and environmentally conscious timber structures. Discover the future of timber engineering, where innovation and sustainability converge to redefine what's possible in the built environment with glued-laminated-timber, hardwood, and finite element analysis. Explore the benefits of combined glulam and its impact on bending strength and modulus of elasticity through experimental testing. Unveiling the potential of oak and other hardwoods in timber construction, this study offers a comprehensive look at GLT's future.
