然而,通用软件不免在某些专业领域中有所欠缺,如该软件还不具备直接求解桥梁问题的能力。
这些不足势必会阻碍该软件的推广和使用。
因此,实现其在桥梁工程中的二次开发与应用是十分迫切的。
针对上述问题,本文提出采用ANSYS提供的二次开发技术进行桥梁问题求解,并将其成功地应用到确定斜拉桥成桥恒载索力检算中,本文利用ANSYS二次开发技术开发斜拉桥成桥状态恒载索力检算程序,并为以后其他斜拉桥的分析计算提供了方便,为以后类似问题的ANSYS开发提供一些思路。
1 ANSYS的二次开发技术1.1 用户程序界面设计技术ANSYS为用户进行程序界面设计提供了一种专言即UIDL(User Interface Design Language)。
UIDL中程序化的语言,它允许用户改变ANSYS的图户界面(GUI)中的一些组项。
UIDL提供了一种用户灵活使用、按个人喜好来组织设计ANSYS用户界面的强有力工具,它在ANSYS的命令中架设其他用户程序与ANSYS之间的桥梁方面起到不可低估的作用。

鉴于斜拉桥施工过程和成桥状态的相关性，尤其在施工阶段结构体系不断转换的过程中，结构的内力和位移变化更加复杂，因此模拟分析斜拉桥的施工过程与控制成为了目前研究领域的热点研究课题[1]。
在学习和总结前人研究工作的基础上，运用有限元软件ANSYS参数化设计语言（ANSYS Parametric Design Language，简称APDL）建立空间三维梁杆单元计算模型，对某斜拉桥施工过程进行模拟，并与有限元软件MIDAS/CIVIL计算结果[2]进行对比，用以校正模拟结果的合理性和准确性。
1 斜拉桥施工过程模拟1.1 基本原理斜拉桥作为高次超静定结构，其结构计算是比较复杂的。
鉴于斜拉索是斜拉桥的主要承重构件，斜拉索索力可以看作是作用在主梁或主塔上的集中力，把主梁或主塔单独取出，可以看作有多个集中力作用的连续梁或悬臂梁，由此可以找出斜拉索索力与主梁内力之间的关系[3]。
首先假定定义二者之间的关系为如式（1）所示。
式中：F——斜拉桥主梁或主塔的内力矩阵；T——多个斜拉索的索力矩阵；D——索力与主梁内力之间的关系矩阵。

（２）荷载工况，荷载和单元强度随机变量分布 对于该公铁两用斜拉桥而言，在满载的火车荷载和汽车荷载情况下，汽车荷载占的比例小于５％，而且 下面的分析表明失效单元大多集中在主梁体系下层的铁路桥面内，上层公路纵横梁和上弦杆都很安全。因 此，我们可以认为，汽车荷载对该结构可靠性的影响可以忽略。通过对比计算，选取了一种火车荷载接近 满载的荷载工况作为可靠性分析的外载，并视为广义荷载ｌ。 假定外载和单元许用应力均服从正态分布，外载和单元许用应力相互之间统计独立，而各单元许用应 力之间的相关系数为０．７．具体统计参数见表１，其中Ｌ为外载设置水平，以广义外载即选定的荷载工况 为一个基本计量单位，基本设置为Ｌ＿１。

本文在自振分析中考虑了斜拉桥的前25阶 振动形态。从第一阶振动频率的0.08864Hz 到第二十阶振动频率为1.3427Hz，我们可 以得出：斜拉桥具有密布的频谱。在一个 较宽的频域范围内，许多振型都有可能被 动力载荷激起强烈的振动；采用十阶以上 的振型分析。同时发现大跨度斜拉桥的柔 度较低，有自振周期长，固有频率低的特 点。

此外，对于铁路桥梁来说，列车过桥是一个瞬态动力学 的过程，结构受载随时间变化，前后时刻的桥梁状态相互影 响。国内外计算桥梁动载的方法是将动载简化为静活载，计
模型，运用与真实情况相符的瞬态动力学的计算方法。随着 数值方法的发展和软件应用，大型有限元软件已经可以建立 与物理模型极其吻合的离散模型来模拟实际结构，分析受力 响应和承载过程。计算结果可以直观、快速、高效地给出结 构静态变形分布、与时间相关的受力情况，为桥梁的强度校 核、设计验算提供高精度、多尺度的数值依据。

索塔式斜拉桥受力性能数值分析与设计建议
索塔式斜拉桥受力性能数值分析与设计建议为了解牵索塔式斜拉桥的力学性能，本文采用有限元软件ANSYS开展了一具体工程的受力分析，建立三维有限元模型，考察在自重、风载和地震作用下斜拉桥的性能，为其合理设计提供可靠的技术支撑。
标签：斜拉桥索塔式ANSYS 有限元分析抗震分析一、引言随着改革开放，我国的经济体系的飞速发展，我们中国已经成为继美国以后的第二大经济和政治体系，这使得结构物在满足使用功能的同时，其对人文环境产生着深刻的影响和对文化韵味传达等方面的功能要求更加凸显出来，索结构中既有巍峨高大且雄浑有力的梁和塔，又有坚韧纤细的悬索，二者互补短长，相辅相成，因而使得众多设计师对这种兼有二者长处的独塔无背索斜拉桥青睐有加，独塔无背索斜拉桥是一种结构独特形式新颖的结构体系，是对常规斜拉桥造型的突破，无背索后倾的塔身形状表现出对相对纤细的桥面强大稳固支撑的力量感，给人醒目深刻的感受。
独塔无背索斜拉桥[1]是利用倾斜主塔的自重来平衡主梁的竖向荷载，取消了背索的使用，形式更加的简单优美受力也更加的合理，本文将以亚洲第一座独塔无背双索面斜拉桥-太阳桥为工程背景进行研究，太阳桥是国内设计最为独特的桥梁之一[2]，它位于太阳岛靠松花江处的河口，整体形状是单个斜臂桥塔，斜拉索全集中在桥塔的钝角一侧。
本文首先回顾了斜拉桥在受力特点结构体系索塔形式等方面的发展历程，总结了独塔无背索斜拉桥的结构特点和发展现状，然后对独塔无背索斜拉桥的索塔结构设计参数和合理成桥状态进行了理论研究。
二、斜拉桥的特点与发展无背索斜拉桥，是景观桥梁中的一种形式，最著名的一座是Alamillo桥，由西班牙的建筑师与工程师Calatrava为1992年世博会建的景观桥，跨度200m，当时桥梁使人为之一振，Calatrava本人也被IABSE（国际桥协）评为杰出青年工程师。
此后，捷克工程师Milan Komínek1995-1998年设计建造了跨Eble河的Mariansky桥，跨度123.5+55.5m。
