抄録(和):
帯鉄筋量が比較的多くせん断スパン比(a/d)が4のRC柱を対象に,静的交番繰り返し荷重下で軸方向主鉄筋量(ρl),帯鉄筋量(ρw)および軸力量が部材の耐力,ダクティリ ィ,復元力特性等の部材挙動に及ぼす影響を比較的大きな断面を有する供試体を用いて実験的に調べた。その結果,部材挙動に大きな影響を与える主要因はρlであること,を明らかにし,さらに,荷重‐変位曲線のモデル化の方法を提案した

LOAD-DEFLECTION CHARACTERISTICS OF REINFORCED CONCRETE COLUMNS UNDER STATIC ALTERNATING CYCLIC LOADS
|
抄録(英):
The objects of the study were columns of reinforced concrete viaducts used in large numbers for railway and urban transportation structures. The influences of variable factore such as longitudinal reinforcement ratio, hoop ratio, and axial load on behaviors of members such as limit states of crack occurrence, yielding and ultimate state of member, ductility, and load-deflection characteristics under static alternating cyclic loads were experimentally investigated. As a result, it was concluded that the load-deflection loop can be modelled as a maximum-point-directed type without slipping, that among various variable factors the influence of longitudinal reinforcement ratio is extremely great, and that plastic hinge length and logitudinal crack formation are determined by the combination of the quantities of longitudinal reinforcement and hoop reinforcement.
