As titel states. My code looks like this:

\begin{equation*}
F_{v,Rk}=\left \{
    \begin{array}{r1}
    & f_{h,1,k} \cdot t_1 \cdot d \\
    & 0.5 \cdot f_{h,2,k} \cdot t_2 \cdot d \\ 
    & 1.05 \dfrac{f_{h,1,k} \cdot t_1 \cdot d}{2+\beta} [\sqrt{2\beta (1+\beta)+\dfrac{4\cdot\beta(2+\beta)M_{y,Rk}}{f_{h,1,k}d t_1^2}}-\beta]+\dfrac{F_{ax,Rk}}{4} \\
    & 1.15\sqrt{\dfrac{2\beta}{1+\beta}}\sqrt{2M_{y,Rk} f_{h,1,k} d}+\dfrac{F_{ax,Rk}}{4} \\
    \end{array} \right
\end{equation*}

This gives this result: enter image description here

I want it to look like this:

enter image description here

Anyone have an idea of how to solve this?

  • I tried doing so. It deleted all pictures, but I reckon you can use the links in the bottom? - Thanks! Commented Oct 4, 2019 at 10:48
  • and make this into a full but minimal self contained documnent that others can copy and test as is. Here we have to guess document class and preamble and that usually ends bad. Help us help you

In the screenshot of your code block, the line

\begin{array}{r1}

is surely wrong, as 1 ("one") is not recognized as a valid column type. You should be getting warning messages to this effect, say, LaTeX Error: Illegal character in array arg.

I assume you intended to use the l ("ell") column type and hence meant to write

\begin{array}{rl} % "ell", not "one"

However, you should really be thinking about pursuing a different approach altogether. I suggest you load the mathtools package for its dcases environment and rewrite your code block as follows:

\[
F_{v,Rk}=\min
\begin{dcases}
row1\\
row2\\
row3\\
\dots\\
row(n-1)\\
rown
\end{dcases}
\]
