In order to meet the B1 layer of large space, removed two columns of B1 layer, then the space between two columns changed from 9 meters to 18 meters. Steel transfer beam (SB1) is used to support the concrete column above the B1 layer, and steel column (SC1) to reinforce remained concrete columns on B1, B2, B3 layers. During cutting column process, 4 pressure sensors were placed to control the forces of jacks, and strain gauges were placed on transfer beam SB1 and reinforcing columns SC1. The whole process was under control, construction safety was ensured.Keywords: supporting beam and replacing column， stress and strain monitoring,
