摘要本文介绍了新型木钢混合地板隔板面内行为的实验和数值研究结果。拟议的隔板系统由用作托梁的 C 形薄壁钢构件和放置在托梁顶部以形成木地板的规格材组成。规格材进一步通过螺钉连接至钢托梁。进行面内载荷测试，以研究所提出的混合膜片的失效模式、面内载荷抵抗能力、刚度退化和能量耗散。在变形特性方面，结果表明，剪切变形占混合膜片面内总变形的90%。隔板的抗荷载行为表现出明显的非线性特征，且刚度下降，并且发现隔板的延性与钢托梁和钢梁之间的螺纹连接的失效模式密切相关。
AbstractThis paper presents the results of experimental and numerical studies on the in-plane behavior of a novel timber-steel hybrid floor diaphragm. The proposed diaphragm system consists of C-shaped thin-walled steel members that are used as joists and dimension lumber that is placed on top of the joists to form a timber decking. The dimension lumber is further connected to the steel joists by screws. In-plane loading tests were conducted to investigate the failure modes, in-plane load resisting capacity, stiffness degradation, and energy dissipation of the proposed hybrid diaphragm. In terms of deformation characteristic, results showed that shear deformations contributed up to 90% of the total in-plane deformation of the hybrid diaphragm. The load resisting behavior of the diaphragm showed an obvious nonlinear characteristic with stiffness degradation, and the ductility of the diaphragm was found to be closely related to the failure mode of the screwed connections between the steel joists and the tim...
