Abstract
In order to investigate the mechanical behavior of curved glulam structures, five-point bending tests were conducted on three typical glulam structures, i.e., glulam curved beam, arch, and beam string. Different failure modes can be observed in the test results, which changed from brittle tensile failure to ductile compressive failure. A series of three-dimensional finite element models were established and verified to be effective. Theoretical analysis was conducted to illustrate the failure mechanism of different structures. The results indicated that glulam beam string can bring into full play the compressive characteristics of glulam. The bearing capacity of glulam string is 820.47% higher than that of curved glulam beam and 204.14% higher than that of glulam arch.
期刊介绍：
European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets.
European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
