连续组合梁的结构性能分析与设计

本文介绍了对组合梁高阶有限元分析模型研究的最新进展。对用来模拟、分析、设计连续组合梁的通用有限元模型进行了深入的介绍、分析及实验论证。本文还检视了栓钉的变形特性对于连续组合梁的结构性能的影响，证明了栓钉的变形特性不仅对组合梁的整体刚度有着重要的影响，还会很大程度上影响组合梁的整体极限承载力。本文对组合梁的结构特性提出了新的认识，为组合梁的性能化设计提出了可行的分析及设计方法。因此，这些模型是用来详细研究组合梁的有效研究工具，它们还是进行组合梁性能化分析及设计的高效手段。合理地使用这些模型还能够对开发更加准确且合理的设计规范产生非常正面的影响。

Performance, Analysis and Design of Continuous Composite Beams

While physical test is always an essential means to study the structural behaviour of a structure,the finite element method has become an effective alternative in the recent years to provide detailed structural responses of the structure for in-depth understanding. This paper reports the latest developments on the use of advanced finite element models to examine,understand and appraise the structural performance of composite beams in buildings. Details of the advanced finite element models of a continuous composite beam are presented together with careful calibration against test data. Moreover,the effects of the deformation characteristics of both shear connectors in continuous composite beams are also examined. The models are considered to be highly effective as a research tool for detailed investigation into the structural behaviour of composite beams,as well as a specialist tool for advanced analysis and design of composite beams. Effective use of the models will be instrumental to the design development of more refined design rules for improved structural accuracy.
