REINFORCED EARTHQUAKE-PROOF SHEAR BLOCK STRUCTURE OF MULTI-SPAN SOLID ABUTMENT-BRIDGE AND BRIDGE GIRDER USING PC BEAM

摘要

PURPOSE: A reinforced earthquake-proof shear block structure of a multi-span solid abutment-bridge and a bridge girder is provided to promote the convenience on construction for a shear block structure and to prevent the shake and domino effect of PC beams by earthquake load. CONSTITUTION: The reinforced earthquake-proof shear block structure of a multi-span solid abutment-bridge and a bridge girder using a PC beam comprises: both side plates fixed on both PC beams using anchors; a left support unit coupled with the side plate and provided with an outer male screw thread; and a shear block structure unit(120) coupled with the left support unit and provided with a right support unit having inner female screw threads to couple with the side plate.
