Createe a PSI inputt data file
Step 1 Create C a new folder and name n it ‘Stattic PSI”, andd then makee it the currennt folder. Copy SA ACINP.DAT T and SEAIN NP.DAT filees from ‘Staatic” directorry to current folder. Step 2 Create C PSI in nput data file Click-on “Data file” icon to laun nch Datagen program, annd select “Crreate new daata file” and he second wiindow pop-u up, as shownn below; seleect “Pile Soill Interactionn” as click-on OK to get th ysis type and d make sure the t unit is Metric M KN. C Click-on Seleect and skip tthe “Title” aand the analy get next step s to defin ne the analyssis options..

Step 4 Select the results to plot Click-on “No” to LC CSEL and PIL LSUP cards. Click on “Y Yes” to PLT TRQ card to get Plot Opttion window and a select th he options sh hown below.
Click-on “Next” and select “Inclu ude all piless in plot”, sellect all load cases to be pplotted. Do nnot define plot size and specify s pile section s data until get Pille Group deffinition. Step 5 Define D pile grroup Define tw wo pile groups and one conductor c grroup, the pilee group ID = =”PL1” and “PL2”; conducto or group ID =”CND”. = Th he first pile group g segmeent length is 10m and seccond segmennt has lengtth of 30m wiith available end bearing g area of 0.6556m^2. Click-on “More” to add a the segm ments or grou ups, and clicck-on “Next”” to finish thhe pile groupp definition n.

Step 6 Define D the pilles Define th he pile head joint, j batter joint, pile grroup ID andd soil ID as shhown in folllowing pictuure for the fo our piles, and d repeat to define d conducctors. Click-on “More” to add a a pile an nd click-on “Next” “ to finnish the pile ddefinition annd get to nexxt step.
Step 7 Define D T-Z data type The pictu ure on right shows s the ty ype of axial data can be defined in n SACS systtem. The data for the t training is i T-Z data. Select “User Deefined T-Z Curves” C and click-on “Next” to o get next steep.
Step 8 Define D T-Z ax xial header data d The head der data defin nes the total number of soil s strata, Z Z-factor, Soill ID and the maximum ddata point of any a T-Z curv ves. The dataa should be got from thee Design Speecification foor this training, and is shown in follo owing picturee.
