Analysis & Design of RCC shear walls in the model using ETABS

Aim: Analysis & Design of RCC shear walls in the model using ETABS.

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.

• Etabs is totally run based on the IS codes which are IS - 456 ,IS - 800 , IS 1893..

The etabs file for a G+6 building is provided. Run the analysis and design the RCC shear walls (show in the etabs model). The following challenge deals specifically with the shear wall of size 300x1500 at grid A-11 in the structural model.

• Extract values of longitudinal steel ratio, boundary element length and shear reinforcing ratio from the design results.
• Provide cross sectional steel arrangement of the shear wall from its base up to terrace, in compliance with provisions of IS 13920 – 2016. AutoCAD application can be used for this exercise. Alternatively, it can be drawn by hand as well.
• Provide elevation drawings of the reinforcement details of the shear wall from base up to terrace.

Procedure :

• open the downloaded attachment G=6 building file in Etabs.
• analyze the structure and start shear design and check .
• select the grid A,11 shear wall show only selected elements.
• then open the design info of peir longitudinal reinforcement,and Per shear reinforcement and peir edge ,boundary width zones take a snap of each detail.
• design the shear wall according to area of steel weather in longitudinal and shear and confining reinforcement .
• next draw the elevation of shear wall of grid A,11.
• take a snap of each detail.up load it in results.

RESULTS:-

• The shear wall is designed in detail from the Etabs software.
• Provided the details of longitudinal and shear reinforcement and buondary elements for the Grid A,11 shear wall.
• the shearwall cross sectional & elevation details are drawn by using hand.
