篷布张力屋顶,是近二十多年来发展起来的一种新型结构。用这种结构建成的屋顶,用料最省,而造型新奇,非常惹人注意。篷布张力屋顶是在悬索结构的基础上发展起来的。它利用撑杆或撑架,加上钢索、篷布和拉固点,形成各种形状像帐篷一样的结构。现代化学工业的发展,各种合成纤维、玻璃纤维、金属纤维篷布和各种新涂料的出现,使篷布在轻质、高强、耐高低温、防火、防尘、防紫外线和加大透明度等方面有很大突破,为这种结构提供了广阔的前景。篷布张力屋顶看起来很简单,但它不是旧式马戏班子的那种帐篷,它的钢索不是随便挂在那里就行了,这方面所遇到的问题要比凭直觉估计到的问题更多。对这种结构,必须给它们加上一定量的预应力,形成一定的结构造型,使
Tarpaulin tension roof is a new type of structure developed in the past two decades. The roof constructed with this structure is the most economical material, and its novelty is very attractive. The tarpaulin tension roof is developed on the basis of the catenary structure. It uses struts or struts, plus steel cables, tarpaulins, and pull-points to create a variety of tent-like structures. The development of modern chemical industry, the emergence of various synthetic fibers, glass fibers, metal fiber tarpaulins and various new coatings, make the tarpaulin lightweight, high-strength, high-low temperature resistance, fire resistance, dust resistance, UV protection and increased transparency. There have been major breakthroughs in such aspects, providing a broad prospect for this structure. The tarpaulin tension roof looks very simple, but it is not the kind of old-fashioned circus tent. Its steel ropes are not hung up there. There are more problems in this respect than intuition. For this type of structure, a certain amount of prestressing must be added to them to form a certain structural shape.
