本文提出了一种新型的大跨度屋盖结构体系--纤维增强聚合物（FRP）编织网结构。FRP WWS由轻质、高强度和耐腐蚀的FRP条组成，这些FRP条以理想的图案“编织”成网。每个FRP带的两端分别锚固在内环梁和外环梁上。在施工过程中，内环梁被一组预应力筋或悬挂在内环梁上的重物迫使移出平面，这在FRP腹板中引起张力并赋予腹板几何刚度以抵抗各种外部载荷。本文首先介绍了简单的玻璃钢WWS的基本布置、条形锚固系统和施工方案，然后描述了一些更复杂的玻璃钢WWS形式。接下来提出了一种用于数学描述玻璃钢WWS三维几何配置的矩阵方法，该方法提供了一种工具来计算..
This paper presents an innovative large-span roof system, namely the fiber-reinforced polymer (FRP) woven web structure (WWS). A FRP WWS is composed of light-weight, high-strength, and corrosion-resistant FRP strips that are “woven” into a web in a desirable pattern. The two ends of each FRP strip are anchored on an inner ring beam and an outer ring beam, respectively. During the construction process, the inner ring beam is forced to move out-of-plane by a set of prestressed tendons or by a heavy mass suspended from the inner ring beam, which induces tension in the FRP web and imparts geometric stiffness to the web to resist a variety of external loads. In this paper, the basic layout, the strip anchorage system, and the construction scheme of a simple FRP WWS are first presented, followed by a description of some more complex forms of the FRP WWS. A matrix approach for the mathematical description of the three-dimensional geometric configuration of the FRP WWS is next proposed, which provides a tool to e...
