連續剛構ansys的實例教程
進入20世紀90年代以來，預應力砼連續梁橋和連續剛構在我國發展迅速，形勢喜人。但是隨著橋跨的增大，連續剛構橋在使用過程中的問題也凸顯出來，其中之一就是隨著使用年限的增加，隨著使用年限的增加，跨中持續下撓并伴隨有大量裂縫的產生，許多大跨度的橋梁都有類似的現象發生，這會使橋梁運營期內出現不良線形而引起乘客的不舒適感，甚至危及行車安全。
原因有很多方面，我們現在主要從軟件的設計方面找原因。大家知道，橋梁在設計的過程中，大都采用平面分析發，其實這并不能完全符合橋梁實際的受力狀態，那么我們怎樣防止或減少連續剛構這些病害的發生呢？這就需要我們按實際受力狀態對橋梁進行分析，即本文前面提到的空間仿真分析。
大家可以把做過的甚至是收集到的命令流或者方法、問題貼出來，大家共同探討。

Abstract
when to do bridge maintenance and which individual component of the bridges needing maintenance is a world problem at present, and the health monitoring system is considered to a very helpful tool for solving this problem. As the continuous monitoring over a long-term period can increase the reliability of the assessment, so, a large number of strain data acquired from the structural health monitoring system (SHMS) installed on a long-span prestressed concrete continuous rigid frame bridge is adopted in this paper. Firstly, a calculation method of point time-dependent reliability is proposed based on the basic reliability theory, and introduced how to calculate reliability of the bridge by using the stress data transformed from the strain data. Secondly, combined

4.1 Example analysis
Take the data collected from the sensor named 2-3MID-2 embedded in the mid-span section base plate between 2# and 3# pier of the bridge for example, process the data according to the method suggested in Section 3.3, convert the data into stress data, and then do statistical analysis of the stress data and deal with the statistical data by Gauss distribution fitting, which can be seen in Fig. 5.
Fig. 5 Stress distribution statistics and Gaussian distribution fitting
Through the above statistics analysis of the converted data, the mean and standard deviation of the measured load effects probability distribution can be obtained for each time section, of which the
