Research And Application Of Data Processing Based On The Visualization Techniques Of Damping

Visualization of calculation results of the dynamic response of the building structuredamping is important. The one hand, the calculation is no longer simply reflect the data used,but the image of a graphic or image displayed visually boring data, abstract, difficult tounderstand the principles and laws becomes easy to understand, more realistic image of theunderstanding of the seismic system isolation system, seismic systems and seismicperformance of the isolation system becomes intuitive and easy; On the other hand, theintroduction of visualization in scientific computing has significant social and economicbenefits. Since analysis of the dynamic response of building structures damping the need forseismic tests, these tests can study the role of process and structure of power of the earthquakefailure process, however, the test simulates not all cases, and the cost is also very expensive.The calculation and analysis of the lessons of previous earthquake experience and lessonslearned, combined with the seismic test results, you can further improve the reliability of thestructure.If you use the traditional method, not only a heavy workload, amount of data, andanalysis of the seismic test is not comprehensive. The visualization techniques can bemodified experimental parameters, to simulate the response of the whole process and allpossible, in order to improve work efficiency and quality, and reduce cost.This paper studies the construction of seismic data visualization. In-depth analysis andsummarize the results of previous studies based on the integrated use of visualization inscientific computing technology, and visualization system to build the appropriate platform;Windows XP platform using Visual C++development tools, call the OpenGL3D graphicslibrary, visual analysis of data; according to the visualization of processes: datapreprocessing, mapping, drawing, showing the four steps to design the structure of thebuilding seismic data visualization; simulation of building vibration data visualization.Data analysis software provided by the seismic experiment platform only forsingle-channel data analysis, we use visualization techniques for multi-channel data pooled analysis [4], the first is the County’s basic single-channel data show, on this basis in thetwo dimensional plane is displayed on the multi-channel data can affect the overall concept ofpersonality building body shaken. We hope that the overall analysis of the data to find outmore laws, these laws cannot be reflected in the single-channel data analysis, these laws onthe building body has an important role of evaluation. And in-depth analysis and summary ofthe results of previous studies based on the integrated use of scientific computingvisualization techniques to provide the necessary conditions for the implementation of thevisualization system.The main subject of several modules:(1) to read the data collected in the buildingvibration test, and data preprocessing;(2) to analyze data and screening;(3) the interpolateddata points to use to build their own conversion function to convert geodetic coordinates intoscreen coordinates;(4) general-purpose3D visualization development tools-the OpenGL inVC++/MFC framework, the interpolation of data points in a desktop window is displayed.
