BARF is a collection of programs for structural analysis and design written in Go.

Overview

• Direct stiffness analysis (/kass): Direct stiffness analysis of (2d/3d) bar member frameworks.
• RCC design (/mosh): Design of rcc slabs, beams, columns and footings as per is456 and bs8110.
• Steel design (/bash): Design of steel beam and column members as per bs449.
• Timber design (/tmbr): Design of timber beam and column members as per is883.

Getting started

Prerequisites

• Go
  • follow instructions at https://go.dev/doc/install
• Gnuplot
  • follow instructions at https://sourceforge.net/projects/gnuplot/files/gnuplot/

Usage

Clone and build this repo -

git clone https://github.com/akhileshsv/barf  
cd barf  
go build -o barf.exe

Run tui menu (uses https://github.com/AlecAivazis/survey) with -

./barf.exe -tui

Note - using "read json txt" as an input option copies the base struct to clipboard and opens a new editor window to edit struct fields.
Hit "?" to see an explanation of individual struct fields (as seen in the gifs below); paste the struct into the editor (ctrl + v) and save the edited file before exiting the editor window.
