摘要

摘要: 为了推广模块化钢结构在实际工程中的广泛应用，解决现有模块间节点连接形式中的连接件连接性能较弱、螺栓安装较为困难以及梁柱焊接时焊接质量难以保证等综合问题，提出一种采用单边螺栓和内套筒连接钢结构模块单元的节点。该节点主要包含内套筒、高强单边螺栓、方钢管柱、H型钢梁等。通过有限元软件ANSYS对建立的4种连接节点进行静力加载和低周往复加载，分析了4种节点的破坏模式、弯矩承载力、滞回曲线、骨架曲线、耗能性能，最后参照现有结构工程，将研究所得到的节点力学性能参数赋予到MIDAS/Gen建立的多层钢结构整体模型中，并对结构模型施加恒载、活载、风荷载及地震作用，进一步探究节点在整体结构中的连接性能。结果表明：楼板梁采用单侧外伸端板时，可提高节点抗弯承载力约8.32%；使用中间连接螺栓和盖板时，可分别提高节点抗弯承载力约16.61%和10.33%；在端板为平齐端板时，节点滞回曲线产生明显捏缩现象，耗能性能显著降低。该节点连接性能在满足GB/T 50011—2010《建筑抗震设计标准》要求的同时，具有较好的耗能性能，节点连接性能满足8层及以下的多层纯模块化钢结构。

Abstract: In order to promote the widespread application of modular steel structures in practical engineering and solve the comprehensive problems of weak connection performance of connectors， difficulty in bolt installation， and difficulty in ensuring welding quality during beam-column welding in the existing forms of joint connections between modular units， this paper proposes a type of joint design for steel modular units using single-sided bolts and inner sleeves. This joint mainly consists of inner sleeves， high-strength single-sided bolts， square steel pipe columns， H-shaped steel beams， etc. By using ANSYS finite element simulation software to perform quasi-static and low-frequency reciprocating loading on the four established connection modes of joints， the failure modes， bending moment capacity， hysteresis curve， skeleton curve， and energy dissipation performance of the four nodes were analyzed. Finally， referring to existing structural engineering， the mechanical performance parameters of the joints obtained from the research were assigned to the overall multi-layer steel structure model established by MIDAS/Gen， and the structure was subjected to dead loads， live loads， wind loads， and seismic actions to further explore the connection performance of joints within the overall structure. The results showed that when a single-sided extended end-plate was used in the floor beam， the bending capacity of the joint increased by approximately 8.32%. When intermediate connecting bolts and cover plates were used， the bending capacity of the joint increased by approximately 16.61% and 10.33%， respectively. When the flush end plates were used， the hysteresis curves of the joint significantly exhibited pinching phenomenon， significantly reducing energy dissipation performance. The connection performance of this joint not only met the requirements of existing specification（GB/T 50011-2010） but also exhibited good energy dissipation performance， meeting the requirements of multi-layer pure modular steel structures up to 8 stories.
