Introduction

Initial modeling is performed using a template.
Below are the inputs.

After initial modeling, modeling of ACI SP273-1 was implemented using the Edit function, define Tie Types, and define Strut Types.

Using Edit Function :  stretch, move, copy, paste, mirror, etc

Two load combinations were applied and each modeling was applied.

Below are the Project Information inputs.

Below are the General Properties inputs.

Below are the Area Properties inputs.

< Structural Shape and Loads >

< Modeling 1 >

< Modeling 2 >

< ESO >

< Stress Flow >
