Effective Stiffness of Horizontal Joints in Precast Concrete Large Panel Structures

프리캐스트 콘크리트 대형판구조물의 수평접합부 유효강성

Though stiffnesses of joints in precast concrete (P.C) large structures are known to be generally less than those in monolithic reinforced concrete wall structures, designers have very little information on the quantitative values with regards to these stiffnesses. The aim of this paper is to provide this quantitative information, in particular, on the compressive stiffness of horizontal joints, based on the analytical results derived from several experiments. Also, it is shown that the approach from the contact problem to determine this stiffness gives a value very similar to those obtained above.
