횡하중 저항 슬래브-기둥 접합부의 펀칭전단 및 불균형모멘트 강도모델

다국어 초록 (Multilingual Abstract)

A reinforced concrete flat plate is a two-way slab without projecting beams, drop panels, or column capitals. This is a structural system favored by many designers for its simple form-work, flexible layout, and economical construction. The design of a flat plate is often controlled by shear and moment transfer between the slab and the columns. The strength in shear and unbalanced moment is affected by loading conditions such as balanced or unbalanced loads applied to slab-column connections. However, the strength models specified in ACI 318-08 Building Code do not consider the effect of the loading conditions. Thus, unconservative design in punching shear and uneconomic design in unbalanced moment can be drawn in the condition that unbalanced load predominates. In this paper, new strength models considered the effect of loading conditions were proposed for lateral load resistant slab-column connections.
