Big span structure of FRP network analysis and forecast

Abstract: this article will introduce a new big span structure, FRP netting structure. In a FRPWWS structure, high intensity of FRP materials like Chinese bamboo weaving of bamboo is a planar formation in the mesh network, the periphery of the structure of the anchorage in a JuanXing beam, the structure of the center for the anchorage netting another within the parameters. Threads on knitting production structure on the initial stress and advance within the parameters of surface movement to meet additional tension of various load resistance. Due to the high FRP materials, materials - weight ratio of this new form for some big span structure of space construction provides an attractive option, the span longer than conventional structural materials building span. In this paper, firstly introduces the basic structure of FRPWWS simple steps, then layout and construction illustrates three basic types of weaving structure, but also put forward some changes this way. This paper introduces a simple mechanical model for the mechanical deformation of FRP single, also gives an example of the structure of the finite element analysis process.

A, introduction

FRP is a new type of structural materials, in recent years in civil engineering research is very active. Because he has some good performance, such as corrosion, light weight, high strength, good fatigue resistance and low cost of maintenance, it was thought to be built in new century building long-span structure of ideal, but it is in some aspects of the traditional mechanical properties and structure of the material or have obvious difference, such as its various heterosexual phenomenon. Due to the uniqueness of FRP materials, the effective use of FRP materials and traditional building materials can span, it is necessary to study the new big span structure. Maeda et al. (2002) is built with the idea of FRP materials 5000 metres of suspension bridge span
In this paper, the FRP netting structure of a kind of brand-new big span structure. This new structure form in a large span to try to effectively use the roof of FRP material performance. In FRPWWS structure, high intensity of FRP compiling Chinese traditional bamboo as the same are woven into a bamboo plane mesh structure. This mesh structure parameters on the anchoring outside outside, the structure of the center and a smaller parameters used in anchorage ribbon. Figure 1 is a small FRPWWS structure model. "Weave" to ensure the smooth of FRP materials at first, to the extent of FRP weave on the prestressed concrete. Then, through the surface movement within the parameters of FRP netting, to pull through the process of prestressing tendons tensile or may have certain parameters including the gravity. Therefore, the FRP nets formed a with two parameters of large-span roofs, the FRP nets set stiffness can resist all sorts of load.
FRPWWS structure similar to the cable networks or cable retinal structure: they constitute part is flexible, By stretching and caused to resist geometric stiffness of load. However, FRPWWS structure has its unique advantages: (1) the weight of FRP materials of low and vertically superior materials properties are effective utilization and transverse weaknesses, but not exposed in the structure of large span of FRP system is ideal, (2) the interchange of FRP plait will produce the huge damping, thereby strengthening structural anti-seismic capability, (3) there are rules of netting modelling makes surface is beautiful, (4) due to corrosion and gravity small installation and maintenance costs low.
This paper introduces a simple FRPWWS structure of the basic layout and construction steps. The plane was roughly threads for three. Also puts forward some practical application examples of the FRPWWS space. Proposes a used nets in the mechanical model of single FRP. Finally describes a simple analysis of finite element method FRPWWS examples.

Second, simple FRPWWS layout
A summary of FRP netting structure includes a FRP weaving, used to anchor the outer ring beam and inner beam and one for the extra gravity tension loading or a group of prestress reinforcement, as shown in figure 1.
Nets are woven from article by FRP, also recommend guest FRP or other high-performance carbon fiber hybrid woven article. Carbon fiber FRP in recent years is widely applied to high strength concrete structure of new materials, it is usually made by extrusion, including fiber to 65%. By China and the Swiss production of two kinds of representative products performance data in table 1 shows prosperity.
Due to the density of woven material, small and easy to be bent and uncoiling. A standard of performance such as table 1 similar carbon materials can withstand FRP greater than or equal to 400KN tension, while a 300m long this strip 70kg less weight. As compared to the same intensity has more than 300m wire 500kg weight.
These woven article according to certain spacing is arranged in an appropriate form of plane. One of the most simple weaving method is a belt, and the other by vertical band, to make up like a fabric of net surface. This type of netting structure can see figure 2 partial screenshots. But in most cases, the number of under-colunm crossing-beam in between each other and the Angle, is the main measure of netting style; Every two ribbon to 90 ° fellowship as shown in figure 3 (a), three little is 60 ° belt in the intersection, as shown in figure 3 (b), as shown in figure 3 (c) and the four ribbon 45 °. At intersections, when fully forming available to all the attached agglutinate FRP interoperability or no adhesion between which can slide freely. In the example, behind will introduce to the static friction between the weaving of the stiffness and static load under dynamic loading sliding friction can consume the kinetic energy
大跨度FRP网架结构的展望和分析

摘要：本文将会介绍一种新的大跨度结构，FRP织网结构。在一个FRPWWS结构中，高强度的FRP材料条像中国竹席中的竹片一样被编织在一起形成一个平面网，这个网状结构的外围锚固在一个圈形的梁上，结构的中心处还有一个用于锚固织网的内圈梁。织网结构靠编织生产时的初步预施加应力和内圈梁面外运动引起的附加张力调整来抵抗遇到的各类荷载。由于FRP材料的具有较高的材料-重量比，这种全新的结构形式为一些大跨度的空间建设提供了一种具有吸引力的选择方案，该跨度长于用常规结构材料建筑的跨度。在本文中，首先介绍了简单的FRPWWS结构的基本布局和施工步骤，接着阐明了三种基本的织造结构，同时也提出了此类结构方式的几种变化。文中介绍了一个简单的力学模型用于单个的FRP条力学变形，也给出了一个实例结构的有限元分析的过程。

一、 引言

FRP是一种新型的结构材料，近年来在土木工程中的研究很活跃。由于他具有一些良好的性能，如抗腐蚀，重量轻，强度高，抗疲劳性好以及维修费用低，它被认为是在新世纪建造大跨度结构的理想建材，但是它在某些方面的机械性能与那些传统的结构材料还是有明显的区别，譬如它的各项异性现象。由于FRP材料的独特性，为了FRP材料的有效使用以及获得传统建材所不能及的跨度，有必要研究新型的大跨度结构。Maeda et al.(2002)就设想了用FRP材料建造跨度5000米的悬索桥。
本文提出了FRP织网结构结构，一种全新的大跨度结构形式。这种新的结构形式旨在试图在一个大跨度的屋顶中有效利用FRP材料的性能。在FRPWWS结构中，高强度FRP编制像中国传统竹席中的竹片一样被编织成一个平面网状结构。这个网状结构的外沿锚固在外圈梁上，结构的中心处还有一个较小的内圈梁用于锚固织带。图1所示既是一个小型FRPWWS结构模型。为保证进行“编织”时FRP材料条的平直，首先要对FRP编织条施加一定程度的预应力。然后，通过内圈梁的面外移动来拉动FRP织网，施加预应力的过程可以通过预应力筋拉伸或在内圈梁设一定的重力来达成。 因此，受拉的FRP网形成了一个带有两个圈梁的大跨屋面，该FRP网的集合刚度能抵抗各种荷载。
FRPWWS结构类似于索网或索网膜结构：他们的构成部分是灵活多变的；并且靠拉伸引起的几何刚度来抵抗各种荷载。然而，FRPWWS结构有其独特的优点：（1）FRP材料自重低且纵向上优越的材料性能被有效利用，而横向上的弱点却没有暴露出来，因此在超大跨度的结构中FRP系统是理想的；（2）FRP编条的交汇处会产生巨大的阻尼，从而加强结构抗风抗震能力；（3）有规则的织网造型会使表面比较美观；（4）耐腐蚀并且由于自重小安装和维护成本低。
本文详细介绍了一个简单的FRPWWS 结构的基本布局和施工步骤。织网的平面被大致的归为三类。同时提出了一些实际应用的空间FRPWWS的例子。提出了一个用于网中单一FRP条的力学模型。最后描述了有限元法分析一个简易FRPWWS的例子的结论。

二、 简单FRPWWS的布局
一个简易的FRP织网结构包括一张FRP编织网、用于锚固的外环梁和内环梁还有一个用于张紧的额外重力荷载或一组被施加预应力的筋，如图一所示。
网是由FRP条编织成的，也客人推荐使用碳纤维FRP或其他的高性能混杂纤维类编织条。碳纤维FRP是近年来被广泛应用于高强度混凝土结构的新型材料，它通常由挤压制造，含纤维比例达到65%。由中国和瑞士生产的两类代表产品繁荣性能资料可见表1。
编织条材料由于密度小而易被弯曲和盘绕。一根标准的性能如表1相似的碳纤维FRP材料可以承受大于等于400KN的拉力，同时一根300m长的这种长条重量少于70kg。作为对比同等强度的300m钢缆自重已经超过500kg了。
这些编织条按一定的间距被编排在一个合适形式的平面上。最简易的编织方法之一就是一根带子与经过的垂直的其他带子上下交错，来制造一个像织物一样的网面。这种类型的织网结构的部分截图可参看图2。但大部分情况下，编织条在交叉点处的数量和互相之间的角度，才是衡量织网样式的主要标准；每两根织带以90°相交如图3（a）所示，三条织带在一点呈60°相交如图3（b）所示，还有图3（c）所示的四条织带的45°相交。在交叉点处，当完全成型后可用附着粘合使FRP条全部互交或不进行粘合使其相互之间可以可以自由滑动。在后面的例子里，会介绍编织条之间的静摩擦有助于静荷载下的刚度而滑动摩擦可消耗动态荷载下的结构动能。
