We study a two-orbital t-J1-J2 model for iron-based superconductors in the presence of a bond disorder(via next nearest-neighbor bond-dilution).By using Bogoliubov de Gennes approach,we self consistently calculate the local pairing amplitudes and the corresponding density of states,which demonstrate a change of dominant pairing symmetry from the s+- wave to d wave as long as J2～J1.
