h2. How is a MIVAN wall system modeled in ETABS?

*Answer:* A {new-tab-link:http://www.architectjaved.com/mivan-formwork/what_is_mivan_formwork.html}MIVAN{new-tab-link} wallsystem systems areis a type of formwork for rapid construction of multi-story buildings. The structures created using MIVAN formwork may have levels without beam systems, instead being composed only of verticalwalls and horizontal slabs.

This type of system may be modeled in [ETABS|etabs:Home] by using [shell|kb:Shell] objects for walls and slabs. Since loadingthese mayarea beobjects resisted entirely by these area objectsresist loading, shells should be adequately [meshed|kb:Meshing] to capture bending, shearing, torsional, and axial behavior. For most models of this type, [staged|kb:Staged construction] analysis will be necessary.

A key concern when modeling MIVAN systems includes islocations where these interconnecting shells transition into transfer girders and supporting columns, which are necessary for levels with uninterrupted areas, such as with parking or the ground floor. To achieve proper connectivity to the walls above, it may be effective to model girders and columns using wall objects. Here, wall stresses should be investigated more closely. Principal stresses may be plotted in ETABS to indicate load path. Arching action in deep girders should also be closely observed in deep girders.
