콘크리트의 應力-變形關係에 關한 實驗的 硏究 : 鋼纖維 콘크리트에 關하여 About steel fiber concrete = An Experimental Study on the Stress-Strain Relationship of Concrete

다국어 초록 (Multilingual Abstract)

The factors adopted in this experiment are volume fraction and the diameter and aspect ratio of fiber. The levels of factors are determined by existing studies.
The effects of the diameter and mixing volume fraction and the aspect ratio for maximum strength, strain and tangent modulus are analyxed based on the linear multiple regression and we obtained regression equations as follows ;
Maximum stress
: σ_max=298.59820+95.78361φ-6.36043V_f+0.62067Ar
Maximum strain at maximum stress
: ε_max=0.021336+0.15746φ+0.05519V_f+0.00181Ar
Tangent modulus
: E=208209.80+87132.84φ-17286.69V_f-464.9181Ar
where φ : diameter
V_f : volume fraction
Ar : Aspect Ratio
