Modelling of 25 storey building with the specified properties using ETABS

Ans:-

Aim:

To Model a 25 storey building on ETABS 2019 with structural properties as specified below. Ground floor or plinth floor level can be taken at a height of 1.5 metres from the base. Each of the successive 25 storeys has a storey height of 3 metres.

Introduction:

ETABS is an engineering software product that caters to multi-story building analysis and design. Modeling tools and templates, code-based load prescriptions, analysis methods and solution techniques, all coordinate with the grid-like geometry unique to this class of structure. Basic or advanced systems under static or dynamic conditions may be evaluated using ETABS. For a sophisticated assessment of seismic performance, modal and direct-integration time-history analyses may couple with P-Delta and Large Displacement effects. Nonlinear links and concentrated PMM or fiber hinges may capture material nonlinearity under monotonic or hysteretic behavior. Intuitive and integrated features make applications of any complexity practical to implement. Interoperability with a series of design and documentation platforms makes ETABS a coordinated and productive tool for designs which range from simple 2D frames to elaborate modern high-rises.

PROCEDURE:

STEP1

• Open E-Tabs ->new file
• A new tab will open
• Use built in settings ->change the units and codes as per indian standard->Click Ok
• A new tab will open

STEP2

• Click on custom grid spacing->Edit grid data->A new tab will open

• Enter the grids ordinates in X direction And Y direction
• Click on Add to made more grids as pers requirement->Click on Ok
• You will be brought back to the previous page(Quick templates page)

• Click on custom storey data->A new tab will open

• Right click on and select "add new story"->Enter number of story you want->enter distance between them
• Select story 1 as the master story and all athers as No(as shown in the above pic)
• Select siimilar to "Story 1"->SO that all other story will be similar to story 1
• Click Ok

STEP3

• Will be taken to template page->click Ok
• The main page will open showing the building structure you designed(shown below)
