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..

D analyssis options Step 3 Define Leave deefault options for both “G General” and d “Output Opptions”, andd click “Nextt”.

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.

Click-on next to get to t next step. Step 9 Define D T-Z so oil stratum data d This step p defines the soil stratum m information n followed bby soil data oof each stratuum (Step 10), the data need ds to be defin ned is number of point of o the curve, stratum locaation and T factors; following g picture sho ows the strattum definitio on of the top soil.

Step 10 Define the soil s data of the t stratum he spec document, thee The dataa is from th picture on o right sh hows the so oil at 0.0m m location. S 9 and 10 to enter alll 8 soil T-Z Z Repeat Step curves.

Step 11 Define end bearing b dataa The pictu ure below will w show up when finish h the step 100. Click-on “Yes” to ennter the Q-Z axial header daata.

Define th he Q-T axial header dataa shown in beelow picturee, click-on “N Next” to acccept the data and get to soiil stratum daata.

Define th he soil stratu um data as sh hown in follo owing two ppictures and rrepeat it for all the stratuums.

Step 12 Torsional data d The torsiional stiffnesss of the soill can be defin ned as linearr spring, folllowing two ppictures givees the detail of the input.

P-Y data d input

The P-Y data input iss similar to Axial A T-Z daata, follow thhe direction of Step 7 too 10 and get the data from m the soil rep port to finish h the input. Followin ng two picturres show thee soil type selection and P P-Y header ddefinition.

Followin ng two picturres show thee stratum and d soil data deefinition at 00.0m locationn, repeat thee input to define d all thee P-Y soils at a rest locatio ons.

Save the file and nam me it PSIINP P.DAT. Section 2
