混凝土夹芯双向板的夹层板理论分析和有限元分析

SANDWICH PLATE THEORY AND FINITE ELEMENT ANALISES OF CONCRETE SANDWICH TWOWAY PANELS

混凝土夹芯板作为一种新型的楼板(屋面板)体系,其应用一直局限于单向板。本文对混凝土夹芯双向板分别采用夹层板理论和有限元分析软件ANSYS进行了分析。两者结果十分接近,证明了有限元分析的正确性。分析结果表明该类板的抗裂性能较好,刚度较大,且具有较高的抗弯承载力,能更好地适应今后楼板(屋面板)体系的发展方向。

Asa kind of new-style floorslab or roof boarding system, concrete sandwich panels have been all along applied to one-way slabs. In this paper, concrete sandwich two - way panels are analyzed by using sandwich plate theory and finite element analysis by using the software-ANSYS, respectively. Both results are in good agreement, which prove the validity of the finite element analysis. The analytical results show this type of panels have preferable crack resistance, stiffness and flexural capacity, which can be adapted to the development of floorslab and roof boarding systems.
