• •The affect of AFM rung interaction on a trellis ladder is studied in low leg coupling limit.•The rung interaction opens a spin gap which increases algebraically with rung coupling strength.•Longitudinal spin-spin correlation shows short range order.•Correlation length decreases with rung interaction following power law.•Large rung interaction induces dimers along rungs. The ground state properties of a frustrated spin-1/2 system is studied on a trellis ladder which is composed of two zigzag ladders interacting through rung interactions. The presence of rung interaction between the zigzag ladders induces a non-magnetic ground state, although, each of zigzag ladders has ferromagnetic order in weak anti-ferromagnetic leg interaction limit. The rung interaction also generates rung dimers and opens spin gap which increases rapidly with rung interaction strength. The correlation between spins decreases exponentially with the distance between them.
