程序图标 ( Program Icon ) 程序介绍 ( Program Introduction) 《核电厂抗震设计规范》GB 50267-97 反应谱计算程序。主要是应网友要求添加的一个小程序。 同时制作这个小程序也可以发现，核电厂使用的反应谱与平时建筑结构规范的反应谱参数定义的方式不一样，而且实际出来的形状也和平时建筑结构规范的反应谱不太一样。核电规范谱通过在对数坐标系下给出特征值点的谱值给出规范谱的定义，如下图所示。 程序界面 ( Program Interface ) 保存数据，并在EXCEL中作图如下。 注释 ( Comments )   ( 如果您发现有错误，欢迎批评指正。邮箱：jidong_cui@163.com . 如果您喜欢这篇博文，请在上面给我 点个赞 吧！         ( If you found any mistakes in the post, please …

ABAQUS超高层结构大震弹塑性时程分析笔记

ABAQUS 做整体分析比较花时间，计算也需要花很多时间，因此，每个过程均需要十分细心，因为错了从来时间成本太大。 不管是前处理建模，还是后处理分析，还有超限文本撰写，都应该是建立在对结构理解的基础上，不能论文一个操作员，能简化，能提高效率的地方就要提高效率，尽量把更多时间用在把握和理解结构机理、结构特性、建立结构概念基础上。

混凝土受拉本构对结构动力时程分析结果的影响[The effects of the concrete tensile constitutive on structural dynamic time hisotry analysis]

为对比小震情况下混凝土抗拉刚度对结构分析的影响，测试三种本构对结构分析的影响：（1）不考虑受拉本构；（2）真实考虑受拉的影响；（3）受拉本构按弹性考虑。以下测试中，所有模型使用的单元类型均一致，均采用纤维梁柱模型，变化的只是受拉部分的本构。通过这两个小例子可以定性说明：（1）一般情况，忽略混凝土的受拉本构，对结构的整体响应分析结果影响不大（虽然这个测试的是小震）。（2）即便结构基本处于弹性（应变小于钢筋和混凝土的屈曲应变），混凝土的受拉区按弹性考虑时的结构整体响应分析结果可能和真实考虑混凝土受拉时的分析结果相差很大。因此反过来也可以说，平时在一般结构分析软件中，采用弹性单元进行小震动力弹性时程分析获得的结构整体响应可能和真实响应相差很大。from 崔济东，崔济东的博客，www.jdcui.com, CJD, JidongCui
