For example use seismosignal for drawing accelerograph, calculating PGA, PGV and PDG and use MATLAB for solving mathematical problems. So we it is better that use special program for their own purposes. 10 after correcting graphs there are little differences in graphs since MATLAB use statistical and mathematical formulas but Seismo signal use engineering formulas. So it count numbers of data, use them as time and use statistical formulas like average and standard deviation to draw graphs.Īs you see in Table1, Table2, Fig. The answer is MATLAB is not Earthquake engineering programmed and it is mathematical base programmed. There is a question that why MATLAB could not Plot graph as same as Seismosignal and calculate time, even you may see error when insert period in matrixes. In plot function C, D or A, D and B, D are in(data, period) format. ylabel function has the same order with xlabel function. In title functions title1-title3 are your graphs title and in xlabel function, xlabel1-xlabel3 are x-axis names. In subplot function x, y are number of rows and columns. you can use labe and title functions to labeling and titling graphs as following instructions.Ī, B, C, D are acceleration, velocity, displacement and period data matrixes. then use subplot and plot functions to plot graphs. In MATLAB define two matrixes which contains period and data('For example acceleration'). In left you can control and copy period and data of each r graphs in right.īy doubble click on each graph you can see max. 3)Be sure that you open acceleration data file in seismosignal.īy click on ok button graphs will plot(Fig. In appearing window after click on open key you can insert time step, line numbers and etc. Know open seismosignal and open data file. By using note pad you could open Data files. In next page click on Acceleration, Velocity and dis placement for each component and save them with. In next page click on the one of record ID. 
Then fill out the form and click on search bottom. Save Earthquake information’s Using Peer Berkley Web Site and Plot Graphs in Seismo Signalįirst search and open " Berkeley. Seismogram is earth displacement datas while occurring earthquake which record by seismograph and could be use to know geological information like plates layers thicknesses.
I cannot write all of them here since limit in number of pagesĪccelerogram is Earthquake ground motion acceleration data which recorde by acclelerograph and could be use to design structures by Earthquake and Structural engineers. Here I use Cape Mendocino 1992 04 25 1806 CPM090Data files as a sample of my research. But first I would like you to know short definition of accelerograph and seismograph before start using software’s. I think that the user did not know seismosignal formulas so use the following Earthquake data to check whether both software’s have the same results or not by checking graphical, PGA, PGV and PGD results. SO it uses formulas to calculate velocity and displacement data. But Seismosignal use acceleration data file only and plot three previous graphs. MATLAB use acceleration data to plot A-T graphs and velocity, displacement data to plot V-t and D-T graphs. Each earthquake engineer knows MATLAB and seismosignal, The two famous software’s. One of these technological development is in engineering softwares. In today world we will see the fast speed of technological development.
