【摘要】 为降低现浇混凝土结构对环境的破坏，响应装配式结构和绿色建筑的发展理念，同时满足吉林省长春市某游泳馆屋顶胶合木梁项目的设计参数需要，通过了解木材各个方向的力学性能，合理地在胶合木梁的不同位置安排木材的排列方式，可以提升胶合木梁的性能。本文通过对兴安落叶松力学性能进行研究，分别对兴安落叶松顺纹、横纹的抗拉、抗压试件进行力学性能试验并得到其应力-应变关系，为兴安落叶松的应用与推广提供试验支撑和理论依据。更多还原

【Abstract】 In order to reduce the environmental damage caused by cast-in-place concrete structures,respond to the development concept of prefabricated structures and green buildings,and meet the design parameter requirements of the glued laminated timber beam project on the roof of a swimming pool in Changchun City,Jilin Province,by understanding the mechanical properties of wood in all directions and reasonably distributing the arrangement of wood at various positions of the glued laminated timber beam,the performance of the glued laminated timber beam can be improved.This paper studies the mechanical properties of Xing’an larch, and conducts mechanical property tests on tensile and compressive specimens of Xing’an larch in longitudinal and transverse directions,and obtains their stress-strain relationships,providing experimental support and theoretical basis for the application and promotion of Xing’an larch.更多还原
