碳纤维加固桥梁结构的健康监测摘要：提出了一种针对老化桥梁的健康监测的可靠性方法。

首先, 根据桥梁的类型提出了临界失效标准。

然后基于这些标准定义安全界限。

假定大量的失效标准是正态分布的随机变量。

基于这样的假设,基本可靠性指标和基本失效概率为每个关键失效模式估计。

已经发现基本失效概率值,桥梁系统失效概率值按这段时间考虑计算。

最后,用系统失效概率来获得桥梁系统的可靠性指标。

系统的可靠性指数用来表达的桥梁在使用期间的状况较为片面。

选择斯里兰卡国家铁路桥网络的一座铁路桥梁作为一个案例研究来说明该可靠度程序。

对于这座桥,失效的最重要的形式是疲劳和腐蚀。

应用程序的建议方法表明,桥梁在现有负载的情况下的现状是令人满意的。

对可靠性的预测,不是为了抵御破坏,而是一种对基础设施管理进行有效的积极的健康监测方式。

关键字：碳纤维结构健康监测状态评估维护可靠性指标失效概率1、介绍在当今迅速变化的世界中,人类的生活质量和国家经济发展依赖于基础设施的数量、质量、和有效性]1[。

在世界各国，民用基础设施通常是需要维护的,康复,或更换的]2[。

特别是对基础设施构成一个相当大的投资的高速公路和相关的地面运输系统，直接影响到一个国家的工业产值。

目前大多数桥梁养护策略基于由桥梁检查员在不同时间间隔进行的视觉检查]3[。

由于人类检测取决于个人检查员,其结果存在一定程度的不确定性。

因此,绝对的依赖检验报告是不可靠的，而且可能导致错误的决策和桥梁拥有者的高维护成本。

基于桥梁的剩余使用寿命维护成本的优化。

另一方面,桥梁的检查员发现结构和非结构化缺陷,破坏和恶化过程的能力不应该被忽视。

事实上,人类经验应该被纳入维护决策,但要有足够的主观的知识。

只在那时,任何可接受的战略才能成为可能。

当前桥梁结构健康监测方法存在许多缺点和普遍的不确定性。

对结构健康监测和桥梁维护的知识不足造成由于频繁的维护活动,不可预见的桥梁损害,和偶然的桥梁失效引起的重大的经济损失。

0 前言利用ANSYS分析钢筋混凝土结构时，其有限元模型主要有分离式和整体式两种模型。

这里结合钢筋混凝土材料的工作特性，从模型建立到非线性计算再到结果分析的全过程讲述了利用ANSYS进行钢筋混凝土结构分析的方法与技巧，并以钢筋混凝土简支梁为例，采用分离式有限元模型，说明其具体应用。

1 单元选取与材料性质1. 1 混凝土单元ANSYS中提供了上百种计算单元类型,其中Solid65单元是专门用于模拟混凝土材料的三维实体单元。

该单元是八节点六面体单元,每个节点具有三个方向的自由度( UX , UY , UZ) 。

在普通八节点线弹性单元Solid45 的基础上,该单元增加了针对于混凝土的材性参数和组合式钢筋模型,可以综合考虑包括塑性和徐变引起的材料非线性、大位移引起的几何非线性、混凝土开裂和压碎引起的非线性等多种混凝土的材料特性。

使用Solid65 单元时,一般需要为其提供如下数据:1)、实常数(Real Constants) :定义弥散在混凝土中的最多三种钢筋的材料属性,配筋率和配筋角度。

对于墙板等配筋较密集且均匀的构件,一般使用这种整体式钢筋混凝土模型。

如果采用分离式配筋,那么此处则不需要填写钢筋实常数。

2)、材料模型(Material Model) :在输入钢筋和混凝土的非线性材料属性之前,首先必须定义钢筋和混凝土材料在线弹性阶段分析所需的基本材料信息,如:弹性模量,泊松比和密度。

3)、数据表(Data Table) :利用数据表进一步定义钢筋和混凝土的本构关系。

对于钢筋材料,一般只需要给定一个应力应变关系的数据表就可以了,譬如双折线等强硬化(bilinear isotropic hardening)或随动硬化模型( kinematic hardening plasticity)等。

而对于混凝土模型,除需要定义混凝土的本构关系外,还需要定义混凝土材料的破坏准则。

在ANSYS中,常用于定义混凝土本构关系的模型有:1)多线性等效强化模型(Multilinear isotropic hardening plas2ticity ,MISO模型)，MISO模型可包括20条不同温度曲线，每条曲线可以有最多100个不同的应力-应变点;2)多线性随动强化模型(Multilinear kinematic hardening plas2ticity ,MKIN 模型)，MKIN 模型最多允许5个应力-应变数据点;3)Drucker2Prager plasticity(DP)模型。

钢筋混凝⼟梁ansys分析附命令流钢筋混凝⼟⾮线性分析2015⼤作业上海交通⼤学陈明1、参数选择梁的截⾯宽度为200mm，上部配置2Φ8受压筋，混凝⼟的净保护层厚度为25 mm（从纵向钢筋外边缘算起），箍筋两端区采⽤8@100的双肢箍，中间区取8@200 双肢箍1）梁的截⾯⾼度选300mm；2）两加载间的距离选1000mm；3）混凝⼟选C30；4）纵向受拉钢筋配筋选218；2、描述选⽤的有限元模型及单元的特点采⽤ansys软件进⾏模拟计算，钢筋混凝⼟模型采⽤分离式模型，不考虑钢筋与混凝⼟之间的相对滑移。

混凝⼟采⽤solid65单元模拟，solid65⽤于模拟三维有钢筋或⽆钢筋的混凝⼟模型。

该单元能够计算拉裂和压碎。

在混凝⼟应⽤中，该单元的实体功能可以⽤于建⽴混凝⼟模型，同时，还可⽤加筋功能建⽴钢筋混凝⼟模型。

另外，该单元还可以应⽤于加强复合物和地质材料。

该单元由⼋个节点定义，每个节点有三个⾃由度:节点坐标系的x，y，z⽅向的平动。

⾄多可以定义三种不同规格的钢筋。

钢筋单元采⽤link180单元模拟，link180是⼀个适⽤于各类⼯程应⽤的三维杆单元。

根据具体情况，该单元可以被看作桁架单元、索单元、链杆单元或弹簧单元等等。

本单元是⼀个轴向拉伸⼀压缩单元，每个节点有三个⾃由度:节点坐标系的x，y，z⽅向的平动。

本单元是⼀种顶端铰接结构，不考虑单元弯曲。

本单元具有塑性、蠕变、旋转、⼤变形和⼤应变功能。

缺省时，当考虑⼤变形时任何分析中LINK180单元都包括应⼒刚化选项。

3、描述选⽤的混凝⼟与钢筋粘结滑移本构关系的具体形式、参数等。

钢筋的应⼒应变关系曲线考虑到极限塑性应变最⼤值为0.01,钢筋本构模型采⽤多线性模型kinh，初始弹性模量为Es=200000Mpa，强化系数为0.001。

混凝⼟的应⼒应变关系曲线混凝⼟选⽤各向同性的miso模型，当计⼊下降端时，程序报错，所以只取了前⾯的上升段，⽤5段折线模拟混凝⼟应⼒应变曲线。
