摘要
"轻型木结构"是北美常见的一种住宅结构形式,它具有施工便捷、抗震性能好等特点。木楼盖是轻型木结构中重要的水平承载构件,它直接承担来自于风和地震的水平荷载,并将荷载传递到木剪力墙上,木楼盖的平面内刚度和承载能力直接影响到水平力荷载在木剪力墙上的分配。回顾了木楼盖平面内抗力性能研究进展,对静力试验、动力试验、有限元模型三个方面的研究成果进行了介绍,希望能对我国的木楼盖平面内抗力性能研究起到借鉴作用。
Light frame timber buildings,with the advantage of fast construction and good performance in earthquake,are wildly used in North America as residential houses.Wood diaphragms are important elements to bear horizontal loads from wind and earthquake and transfer it to wood shear walls.The in-plane stiffness and strength of wood diaphragm have an important effect on the distribution of lateral load in wood shear walls.In this paper,some research works on the in-plane behavior of wood diaphragms,including monotonic static tests,dynamic tests and finite element models were reviewed,which might be useful for the future researches on light frame timber structures in China.
