Abstract_Chinese:为推广钢结构集成模块建筑在抗震设防地区的应用, 解决传统节点不能与模块内部装修配合的技术困难, 提出一种应用于钢结构集成模块建筑的螺栓-封板组合节点．建立了其简化力学模型, 推导了其初始转动刚度和抗弯承载力计算公式, 并通过11个足尺试件的单调加载和循环加载试验对其进行验证．结果表明, 上部模块地板梁和下部模块天花板梁无组合效应, 独立承担弯矩; 所提螺栓-封板组合节点为半刚接节点, 可有效传递地震作用引起的轴力、弯矩和剪力; 节点初始转动刚度和抗弯承载力的试验结果与所提计算公式吻合较好, 验证了节点简化力学模型和理论计算公式．
Abstract_English:In order to promote the application of integrated modular steel construction in seismic areas and to settle the incompatibility of traditional connection with the internal finish，an innovative bolted connection with welded cover plate was proposed. The design formulas of initial rotational stiffness and bending bearing capacity were derived based on the simplified mechanical model. Eleven full-scaled specimens were tested under monotonic and cyclic load to verify the design formulas. It was found that the floor beam of the upper module and the ceiling beam of the lower module showed no composite action and had individual bending behavior. The proposed connection was typical semi-rigid connection and capable of transferring the axial load，bending moment and shear force caused by earthquake. The test results of initial rotational stiffness and bending bearing capacity were in good agreement with the proposed design formulas，indicating the reasonability of the simplified mechanical model and the theory calculation formulas.
