摘要

PURPOSE: A manufacturing method of a composite PC member composed of a prestressed PC and a non-prestressed PC and a composite PC member thereof are provided to minimize the cracking of a PC member caused by applying prestress and to improve the loading performance by accumulating much prestress to a PC member.;CONSTITUTION: A manufacturing method of a composite PC member composed of a prestressed PC and a non-prestressed PC is composed of applying the primary concrete(20) forming the lower part or a part of the PC member, applying prestress to the primary concrete after curing the primary concrete, and applying the secondary concrete(30) forming the upper part or a part of the primary concrete.;COPYRIGHT KIPO 2010
