  The ARGO-YBJ detector, located at the Yangbajing Cosmic Ray Laboratory (4300
m a. s. l., Tibet, China), was a full coverage air shower array dedicated to
gamma ray astronomy and cosmic ray studies. The wide field of view (~ 2 sr) and
high duty cycle (> 86%), made ARGO-YBJ suitable to search for short and
unexpected gamma ray emissions like gamma ray bursts (GRBs). Between 2007
November 6 and 2013 February 7, 156 satellite-triggered GRBs (24 of them with
known redshift) occurred within the ARGO-YBJ field of view. A search for
possible emission associated to these GRBs has been made in the two energy
ranges 10-100 GeV and 10-1000 GeV. No significant excess has been found in time
coincidence with the satellite detections nor in a time window of one hour
after the bursts. Taking into account the EBL absorption, upper limits to the
energy fluence at 99% of confidence level have been evaluated,with values
ranging from ~ 10-5 erg cm-2 to ~10-1 erg cm-2.
