摘要
叙述了研究与开发超大跨度结构的必然性与必要性,介绍了适应这一需要而提出的巨型网格结构体系的结构构成形式与特点;回顾了巨型网格结构的研究状况,包括部分类型结构的适宜跨度、静力与稳定性、动力与地震响应特性及结构简化分析方法等;总结了该体系结构设计的合理参数选择、进行抗震验算所需考虑的地震波作用方向及组合维数、用振型分解反应谱法进行抗震验算所需的振型阶数等。最后指出了巨型网格结构体系研究的关键问题和今后的研究方向。
The necessity of research and development on super-span structures was described.The form and characteristic of the reticulated mega-structure that met need were introduced.Authors reviewed the research status on the reticulated mega-structure,including suitable spans,statics and stability,dynamic and seismic response traits,and simplified analysis methods for some types of reticulated mega-structure.Some results were summarized,including reasonable form parameters of the structure,the reasonable required components of seismic loads for seismic design and reasonable vibration modes combination of vibration mode-decomposition-response-spectra method.Finally,the key and trend of the research on reticulated mega-structure were pointed out.
