摘要

木质建筑因其轻便、耐用、环保、隔热和美观等优点而备受青睐,尤其是在地震地区。剪力墙提供了轻型框架木结构所需的横向阻力,以承受地震荷载。当用胶合板等木结构面板覆盖时,剪力墙可以是坚固、坚硬和有韧性的。研究了胶合板的生产因素(木材种类、板材厚度)和护套材料的纤维方向对剪力墙承载性能的影响。极限载荷下的位移随胶合板厚度的增加而减小。从延展性的角度来看,黑松胶合板是各种木材中剪力墙的最佳覆盖材料。就承载能力而言,苏格兰松木胶合板是木材中剪力墙的最佳覆盖材料。此外,研究发现,垂直于护套材料纤维方向形成的壁比平行于纤维方向的壁能承受更多的载荷。

The Effect of Sheathing Material on Racking Performance of Plywood Shear Wall
Wooden buildings are intensely preferred especially in earthquake regions due to their many advantages such as lightness, durability, environmental friendliness, insulation and aesthetics. Shear walls provide the lateral resistance needed for light-frame wood structures to withstand earthquake loads. When sheathed with wooden structural panels such as plywood, shear walls can be strong, stiff, and ductile. This study focuses on the effects of production factors (wood species, thickness of panels) of plywood and fibre direction of sheathing material on the racking performance of the shear wall. The displacement at ultimate load decreased with increasing the thickness of plywood panels. It was also concluded that the black pine plywood panels were the best sheathing materials for the shear walls among wood species in terms of ductility. Scots pine plywood panels are the best sheathing materials for the shear walls among wood species in terms of load carrying capacity. Moreover, it was found that the wall formed perpendicular to fibre direction of sheathing materials could carry more load than the wall formed parallel to fibre direction.
