I am having trouble with vertically centering all of my formulas between paragraphs and when using itemize. I am using LuaLatex and no usepackages for formula placement.

Code:

\begin{equation}
    \boxed{f_{ft,r2.5,prisme}=0.37f_{R3,prisme}}\label{eq:reststrekkfasthet.1}
\end{equation}

\begin{itemize}
    \item f\begin{footnotesize}{ft,r2.5,prisme}\end{footnotesize} = Reststrekkfastheten til fiberbetongen ved 2.5 mm rissutvidelse \cite{NB15}.
\end{itemize}

\begin{equation}
    \boxed{f_{ftm,r2.5,gulv}=0.75\cdot f_{ft,r2.5,prisme}}\label{eq:Mreststrekkfasthet.1}
\end{equation}

\begin{itemize}
    \item f\begin{footnotesize}ftm,r2.5,gulv\end{footnotesize} = Midlere reststrekkfasthet til fiberbetongen \cite{NB15}.
\end{itemize}

Any tips? I would really like to adjust all the formulas in one go, if that is possible.

Thanks in advance!

    Why are you opening and closin itemize? – egreg May 12 '18 at 12:27

One itemize environment, with several \item statements, should suffice. Also, don't leave blank lines (which create paragraph breaks) between the item's statement and the associated equation environment.

enter image description here

\documentclass{article}
\usepackage[dutch]{babel} % ? Swedish? Norwegian?
\usepackage{amsmath,siunitx}
\begin{document}
\begin{itemize}

\item Some initial claim \dots
\begin{equation}\label{eq:reststrekkfasthet.1}
    \boxed{f_{\textrm{ft},\textrm{r2.5},\textrm{prisme}}
        =0.37f_{R3,\textrm{prisme}}}
\end{equation}

\item $f_{\textrm{ft},\textrm{r2.5},\textrm{prisme}}$\quad 
Reststrekkfastheten til fiberbetongen ved \SI{2.5}{\milli\meter} rissutvidelse \cite{NB15}.
\begin{equation}\label{eq:Mreststrekkfasthet.1}
    \boxed{f_{\textrm{ftm},\textrm{r2.5},\textrm{gulv}}
        =0.75 f_{\textrm{ft},\textrm{r2.5},\textrm{prisme}}}
\end{equation}

\item $f_{\textrm{ftm},\textrm{r2.5},\textrm{gulv}}$\quad 
Midlere reststrekkfasthet til fiberbetongen \cite{NB15}.

\end{itemize}

\end{document}
  • This was of great help, thank you! I have another question if that's ok. When i place formulas inside the itemization, they are centered differently from normal. Is there a way to get the same centering for formulas inside itemization mode? – Harald Kyllingstad May 13 '18 at 10:12
  • @HaraldKyllingstad - There are probably many ways to achieve your objective. One particular way is as follows: (i) Load the enumitem package in the preamble, and (ii) replace \begin{itemize} with \begin{itemize}[wide=0pt, leftmargin=*]. This'll get you almost all the way to your objective. If equation centering has to be absolutely the same inside and outside of itemize environments, leave off the option leftmargin=*. However, this will also entail the text associated with an \item no longer having hanging indentation from the second row; this may, or may not, be acceptable to you. – Mico May 13 '18 at 10:50

The vertical spacings before and after an itemize environment add up to \abovedisplayskip. Just use a single itemize and no blank space between items and equations.

I took the opportunity to add some improvements to your code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\usepackage{mathtools}
\usepackage{enumitem}
\usepackage[detect-all]{siunitx}
\newcommand{\wideboxed}[1]{\fboxsep=5pt\boxed{\;#1\;}}

\begin{document}

\begin{itemize}[before=\sffamily]
\item FR3G = Gjennomsnittskraften avleste ved \SI{2.5}{mm} rissutvidelse \cite{NB15} 
\begin{equation}
    \wideboxed{f_\text{ft,r2.5,prisme}=0.37f_\text{R3,prisme}}\label{eq:reststrekkfasthet.1}
\end{equation}

    \item f\textsubscript{\footnotesize ft,r2.5,prisme} = Reststrekkfastheten til fiberbetongen ved \SI{2.5}{mm} rissutvidelse \cite{NB15}.
\begin{equation}
    \wideboxed{f_\text{ftm,r2.5,gulv}=0.75 · f_\text{ft,r2.5,prisme}}\label{eq:Mreststrekkfasthet.1}
\end{equation}

    \item f\textsubscript{\footnotesize ftm,r2.5,gulv} = Midlere reststrekkfasthet til fiberbetongen \cite{NB15}.
\end{itemize}

\end{document}

  • I think that f\begin{footnotesize}{ft,r2.5,prisme}\end{footnotesize} produces a weird-looking result. Give f\textsubscript{ft,r2.5,prisme} a try? – Mico May 12 '18 at 14:53

    @Mico: You're absolutely right. Of course I focused on the main point of the question. Maybe, since the O.P. seemed to want footnotesize, something like f\textsubscript{\footnotesize ft,r2.5,prisme}? – Bernard May 12 '18 at 15:02
  • Both \footnotesize and \scriptsize should be OK. – Mico May 12 '18 at 15:27
