We study the scaling of two-dimensional crack roughness using large scalebeam lattice systems. Our results indicate that the crack roughness obtainedusing beam lattice systems does not exhibit anomalous scaling in sharp contrastto the simulation results obtained using scalar fuse lattices. The local andglobal roughness exponents ($\zeta_{loc}$ and $\zeta$, respectively) are equalto each other, and the two-dimensional crack roughness exponent is estimated tobe $\zeta_{loc} = \zeta = 0.64 \pm 0.02$. Removal of overhangs (jumps) in thecrack profiles eliminates even the minute differences between the local andglobal roughness exponents. Furthermore, removing these jumps in the crackprofile completely eliminates the multiscaling observed in other studies. Wefind that the probability density distribution $p(\Delta h(\ell))$ of theheight differences $\Delta h(\ell) = [h(x+\ell) - h(x)]$ of the crack profileobtained after removing the jumps in the profiles follows a Gaussiandistribution even for small window sizes ($\ell$).
