h2. How is a MIVAN wall system modeled in ETABS? *Answer:* {new-tab-link:http://www.architectjaved.com/mivan-formwork/what_is_mivan_formwork.html}MIVAN{new-tab-link} wall systems are a type of formwork for rapid construction of multi-story buildings. The structures created using MIVAN may have levels without beam systems, instead being composed of vertical 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 loading may be resisted entirely by these area objects, 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 is 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 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 should also be closely observed in deep girders. |
