【摘要】 应力蒙皮结构是一种新型、轻质、高强结构,这种结构国外已在大跨度的空间结构中开始应用。 本文综述了国外应力蒙皮的发展概况,并以大跨度双曲抛物面应力蒙皮悬挑结构为对象,提出了简化的计算方法,即等代网壳——立体桁架分析法。同时还进行了双曲抛物面应力蒙皮悬挑结构的模型试验,试验表明理论计算与实测结果是基本符合的。更多还原

【Abstract】 Stressed-skin structure is a new type of lightweight and high-strength structure, it is being used in foreign countries for long span space structure.In this paper,the development of stressed-skin structures in foreign countries are briefly described. A simplified approximate analytic method known as the Equivalent Grid Shell-Space Truss Analytic Method is presented for the calculation of long span stressed-skin cantilever structure.A model test of stressed-skin hyperbolic paraboloid cantilever structure has been made and the results obtained from calculation by the given method accord basically with those from the model test.更多还原
