Structural Modelling using Etabs 2018

Procedure-

New model->Grid and storey setting->done->Define-> material properties-> add materil types->ok

Define-> section properties->add beam and column->add beam and column properties->ok

Define->section properties-> slab properties added->ok

Select all storey ->quick draw column-> properties ->choose column properties->select column position->ok

select object->draw beam->properties-> choose beam properties ->quick draw beam-> select beam position->ok

silimar storey selected->draw floor->properties->slab properties selected->draw slab ->ok

go to define->load perform->add load( wall, earthquack,live and dead )->similar storey selected-> assign->shell loads live load(3KN/m2)->apply

select object->beams ->assign->frame load->distributed->brick wall (10KN/m2)

Assign->mass force->modify->live load + dead load+ wall load->apply

define load combination->define->concrete frame->ok

select->object type->floor assign->assign->shell ->diaphrame->apply

analyze->check model->ok

Result-

• Modal mass participation for 1st remotes dominates atleast 65%(achieve for x-axis only)
• mode 1and mode 2 defers by 10% (achieved)
• Principle modes be greater than torsional modes (achieved)
• inter storey drift ratio limited to 0.004 (achieved)
• Axial stress in column and shear wall (achieved)
• Base shear share between shear wall and column( not dual system)
