Abstract：
The reserved engine workshop of Shanghai Shipyard in Binjiang of Shanghai is a large single-floor factory building of assembled reinforced concrete transverse truss structure. High and low span truss was utilized for beam placement in the reconstruction design, but construction risk existed in the instant and intensive transmission of internal force of load-bearing members. Based on investigation of the original structure, axial roof truss beam end space was innovatively utilized and new steel beam was transversely embedded and lifted to lean on and displace the original bracket. The original under-supported truss beam was utilized for roof truss displacement andupper load transmission to the new steel beam. Roof truss was gradually and successfully placed, to enlarge the net height of the connection opening and to satisfy functional requirements of public building. The SHM structure safety monitoring and early warningtechnique was adopted in construction to guarantee construction quality.
