| 中文摘要: |
| 为了探讨不同预制板截面高度与叠合后截面总高度比例对叠合结构力学特性的影响，利用ABAQUS软件对比例为0.6、0.5和3/7的叠合板进行有限元分析.模拟结果表明，该比例的变化对后浇层受压混凝土的“应变滞后”和钢筋的“应力超前”等叠合结构的典型力学性能具有重要影响.本文的研究为叠合结构的设计和工程应用提供了理论基础. |
| 英文摘要: |
| The proportion of the height of pre-cast slab to the total height of composite slab has important influence on the mechanical properties of composite structure, for which the composite slabs(the proportion is 0.6、0.5 and 3/7 respectively) was simulated based on ABAQUS to analyze the specific influence. The results show that the change of the proportion has important influence on the typical properties of composite structure such as strain hysteresis of the compressed concrete, stress excess of tensile steel and so on. The study provides theoretical basis for the design and engineering application of composite structure. |
