结构振动控制代码

说明：  针对轨道动力学，模拟轨道不平顺的matlab编程，对轨道增加不平顺性，美国六级谱(Addition of track irregularity)

说明：  ansys命令流，计算由于振动引起的高层建筑物的表面振动加速度，不过激励是施加在土体上的(ANSYS command flow is used to calculate the surface vibration acceleration of high-rise buildings caused by vibration, but the excitation is applied to the soil)

说明：  黄河流域二级支流shp文件，已经修正过的，做底图很好用的。(Shp files of secondary tributaries in the Yellow River Basin)

abaqus的动态力学数值模拟源文件，适合abaqus新手操作练习使用(ABAQUS source files for numerical simulation of plate constraints, suitable for ABAQUS novice operation exercises)

精细积分法Matlab程序，利用该程序对动力系统的微分方程精细求解。(The program of precise integration method MATLAB is used to solve the differential equation of dynamic system precisely.)

说明：  此程序为本人自行编制的矩形移动荷载作用下饱和土地基的动应力响应问题的MATLAB程序，适合相关研究方向的初学者。(This program is a matlab program for the dynamic stress response of saturated soil foundation under the action of rectangular moving load, which is suitable for beginners in related research fields.)

说明：  可以用该程序进行多自由度结构的地震控制计算(Earthquake control calculation of structures)

说明：  基于ABAQUS UMAT开发的三维导入损伤参数的集料本构模型(Constitutive model of aggregate based on three-dimensional imported damage parameters developed by ABAQUS UMAT)

用于房屋、大坝、桥梁、水电站等大型结构的时程分析，根据桥梁抗震细则规范标准谱得到的25条地震波(For time history analysis of large structures such as buildings, dams, bridges and Hydropower stations, 25 seismic waves are obtained according to the standard spectrum of seismic rules for bridges.)

说明：  模拟金属材料单向压缩过程，用abaqus模拟压缩过程的例子，该非常适合abaqus的初学者(Simulating Unidirectional Compression Process of Metal Materials)
