- Open ETABS software and click on new model, following display will appear. Make below specified settings and click on ok.

- Now,edit grid details as shown below.

- Now,edit story data as shown below.

 - when we click on ok,plan view of the structure can be seen as shown below.

 - Now, go to Define>>add new material>>and create materials M25, Fe500 and Fe415 as shown  below.

 - We can see in the below table that the required materials are added.

- Now, go to Define>> add new property and create beam of size 450*650mm, column of sizes 450*650mm and 650*450mm as shown below.

 - select rectangular 

 - go to modify/showrebar and edit as required as shown below.

 -  Now, go to define>> section properties>> slab sections and add slab125 and STR_SLAB as shown below.

 - Now, using uickm draw column and beam options ,draw columns and beams . we can see the drawn beams and columns in the below figure.

- Using, uick draw slab option ,draw slabs as shown below.

 - Go to define and then to load patterns and enter loads as shown below.

 - Now,select EQX load and go to modify load and edit as shown below.

- Make corresponding changes to EQX+,EQX-,EQY,EQY+,EQY- in the similar way.

 - Go to select and then to slect object type and select floors as shown below.

 

 - go to assign>>shell loads>> uniform and as assign load as shown below.

 - We can see in the below figure that the load has been assigned.

 - Go to select and then to slect object type and select beams as shown below.

 - G o to assign >>frame loads>>distributed and assign load as shown below.

 - We can see in the below figure that the load has been assigned.

 - Now, go to define and then select mass source ,below given table can be seen. 

 - Click on modify/show mass source and edit as shown below.

 - Now, go to define and choose load combinations ,below given display is visible. Click on add new combo.

 - Select concrete frame design in the below display and then click on ok.

 - Following display can be seen .

 - Now go to analyse and choose check model , a dispaly is visile as shown below. M ake required changes as shown below and click on ok.

- We can see that it has been assigned.

- Select points,go to assign and then to support data and then to point springs and make reuired changes as shown below and then assign to piles.

 

 - assign loads, analyse and get slab strip design results .
