thank you Heiko Oberdiek for your reply.

I was surprised by the answer that the value of documentclass is not in some variable somewhere.

My solution was relatively easy.
I am developing my suite using a Single-Sourcing model

Single sourcing: building modular documentation [Book] by Kurt Ament i

so I have only two files with documentclass.

in each I added a new variable:

- - - doc-class-article.tex - - -
\documentclass[10pt]{refart}
\newcommand\DocClass{refart}

- - - doc-class-book.tex - - -
\documentclass[10pt]{refrep}
\newcommand\DocClass{refrep}

added \usepackage{ifthen}

after testing this
at the beginning of the chapters

\ifthenelse{\equal{\DocClass}{refrep}}{%
\chapter[\DocTitleShort]{\DocTitle}%
}{\relax}%

and adding this to each part:

\ifthenelse{\equal{\DocClass}{refrep}}{%
\part[\DocTitleShort]{\DocTitle}%
}{\relax}%

I saw that I could make a macro:

\newcommand\addsectioning[1][chapter]{%
\ifthenelse{\equal{\DocClass}{refrep}}%
{\#1[\DocTitleShort]{\DocTitle}}{\relax}}%

which didn't work: \#1 does not expand correctly

final version:

\newcommand\addsectioning[1][chapter]{%
\ifthenelse{\equal{\DocClass}{refrep}}%
{\ifthenelse{\equal{#1}{chapter}}{\chapter}{\part}
[\DocTitleShort]{\DocTitle}}{}}%
%usage:
%\addsectioning%chapter
%\addsectioning[part]
