摘要:
提出了一种适用于钢板组合梁(SPCCT梁) 的平钢板-栓钉组合连接件(PSCC)，有望提高钢板组合梁的施工效率与便利性。为了解该型连接件钢板组合梁(SPCCT梁) 的受力性能，开展了1根SPCCT梁的静力性能试验；采用经试验验证的ANSYS有限元模型，研究了PSCC对SPCCT梁受力性能的影响，结果表明，SPCCT梁具有较高承载力和塑性变形能力，试验梁最终呈剪切破坏形态；相较于使用栓钉连接的SPCCT梁，PSCC可使有板托SPCCT梁的极限承载力提高27.43%，延性性能提升214.02%，使无板托SPCCT梁的极限承载力提高10.97%，延性性能提升53.28%；对SPCCT梁设计时，钢板处的抗剪连接程度应大于工字钢上翼缘处。相关研究可为SCCT梁在实际工程的推广应用提供参考借鉴。
Abstract:
A plate-stud combination connector (PSCC) for I-beam-flat steel plate concrete combined T-beam (SPCCT) is proposed, which is expected to improve the construction efficiency and convenience of steel plate composite beams. To understand the stress performance of SPCCT with this type of connector, the static performance test of one SPCCT beam was carried out；and the effect of PSCC on the stress performance of SPCCT beam was investigated by using the experimentally verified ANSYS finite element model. Results show that: the SPCCT beam has high load carrying capacity and plastic deformation capacity, and the test beam finally shear failure pattern；compared with the SPCCT beam with bolted connections, the PSCC can increase the ultimate load carrying capacity of the SPCCT beam with plate joists by 27.43%, and increase the ductility performance by 214.02%, so that the ultimate load carrying capacity of SPCCT beam without plate supports is increased by 10.97%, and the ductility performance is increased by 53.28%；for the design of SPCCT beam, the degree of shear connection at the steel plate should be greater than that at the upper flange of the I-beam. The related research can provide reference for the popularization and application of SPCCT beam in practical engineering.
