The National Conference Center project has a complicated structure form,varied curvy shape,diversified cylinder columns and special-shaped components.

国家会议中心工程结构形式复杂,立面造型曲面多变,圆柱和异形构件变化多样,使用常规测量手段难以满足精度要求。

Though the calculation of a piece of box culvert with a special-shaped structure the paper compares the difference between the traditional calculation method and solid finite element calculation.

通过对一块异形结构箱涵的计算,比较了传统计算方法与实体有限元计算的差异;分析了箱涵出入口断面与道路路线夹角在不同角度下的箱涵上部结构受力情况,给出了相对合理的最小夹角值;对出入口处有斜交的箱涵结构添加栅格梁进行计算,分析了栅格梁对箱涵结构受力的影响和作用。

In the recent years, steel-reinforced concrete (SRC) structure and special-shaped column structure are being applied more widly than before in buildings in China.

近年来国内型钢混凝土与异形柱结构的应用日渐广泛,大量的研究成果已经证明了这两种结构体系的优点和适用性。
