Description: 该建筑为一幢六层现浇钢筋混泥土框架房屋，屋顶有局部突出的楼梯间和水箱间。混泥土强度等级：梁为C20，柱为C25。混凝土密度为2500kg/m3
本题目将对该梁柱结构的框架房屋进行模态分析，求解出该结构的前8阶固有频率及其对应的模态振型。框架的平、剖面见图1，图2。构件尺寸参见表1、表2。
其材料为混凝土，相关参数为：杨氏模量C20为2.55e10N/m2 ，C25为2.8e10 N/m
-The building for a six-storey reinforced concrete frame houses, the roof has partially prominent between the staircases and water storage tanks. Concrete strength grade: Leung for C20, column C25. Concrete density 2500kg/m3 will be the subject of the framework structure of the column housing modal analysis, solving of the structure before the 8-order natural frequencies and corresponding modal type. Ping framework, profiles are shown in figure 1, Figure 2. Scantlings see Table 1, Table 2. Its materials for concrete, relevant parameters are: Young s modulus C20 for 2.55e10N/m2, C25 for the 2.8e10 N/m

Description: 本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。-This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.
