摘要

摘要: 木-混凝土组合结构能显著提高木结构建筑的结构性能，在多高层木结构建筑中有较好的应用前景。由于木-混凝土组合楼盖振动性能方面的研究比较少，目前还缺乏有效的设计依据。钢筋桁架楼承板在装配式混凝土结构楼盖中已被广泛使用，对采用钢筋桁架楼承板的木-混凝土组合梁的动力性能开展试验探索。基于推出试验得到剪力连接件的抗剪性能并计算组合梁的抗弯刚度；通过动力试验获取了组合梁的自振频率、阻尼比等动力性能，结合理论计算分析了连接件类型和钢筋桁架楼承板对组合梁动力性能的影响，利用现有标准评估了组合梁的舒适性以及计算模型的准确性。

Abstract: Timber-concrete composite structure can significantly improve the structural performance of timber buildings and can be widely mostly used in multi-story and high-rise timber buildings. However, due to the lack of research on the vibration performance of timber-concrete composite floor systems, effective design bases are still not available at present. Steel bar truss slabs have been widely used in prefabricated concrete structures. In this regard, the dynamic properties of timber-concrete composite beams using steel bar truss slabs were explored experimentally. Through the push-out test, the anti-shear performance of shear connectors was obtained, and the flexural rigidity of the composite beams was calculated. Furthermore, through dynamic tests, the dynamic properties such as natural vibration frequency and damping ratio of the composite beams were obtained. In addition, according to theoretical calculation, the effects of connector types and steel bar truss slabs on the dynamic properties of the composite beams were analyzed, and the comfortability of the composite beams and the accuracy of calculation models were evaluated based on existing standards.
