Performance Analysis of Composite Open Web Sandwich Plate Column Structure

为研究大跨度正交正放混合型混凝土空腹夹层板柱结构的动力性能、静力性能及经济性能,运用有限元分析软件MIDAS/Gen和PKPM建立结构模型,采用对比分析方法,分析了大跨度正交正放混合型混凝土空腹夹层板柱结构体系与大跨度钢筋混凝土密肋井字梁屋盖结构体系的动力性能和静力性能,并进行了经济指标分析。结果表明:该新型结构与传统结构相比自重较轻,在多遇地震作用下,层间位移角和层间位移满足规范要求;在组合荷载作用下,新型结构挠度更小,经济性能更佳。

In order to analyze the dynamic performance,static performance and economic performance of large-span orthotropic composite concrete vierendeel sandwich plate column structure,the finite element analysis software of MIDAS/Gen and PKPM are used to establish the structural model.The dynamic and static performance of large-span orthogonal composite concrete vierendeel sandwich plate column structure system and large-span reinforced concrete multi ribbed well beam roof structure system are analyzed by comparative analysis method,and the economic index is analyzed.The results are as follows.Compared with the traditional structure,the new structure has less weight,and the inter story displacement angle and displacement could meet the requirements of the code under frequent earthquakes;under the combined load,the new structure has smaller deflection and better economic performance.
