Brief of these experimental results are as followes. (1) There is a correlation between impact fracture energy and statical strain energy of the specimens without reference to axial load. (2) Residual strength ofaxial loaded specimens begin to drop down over the critical impact level, then impact fracture energy and impact fatigue strength are both lower than that of un-loaded specimens. (3) Stress-strain curve of the specimen in impact fatigue test changes with increase of repeat number and showes the same process as compressive fatigue test., 長崎大学工学部研究報告, (10), pp.31-40; 1978}, pages = {31--40}, title = {軸圧力を受けるコンクリート短柱試験体の衝撃圧縮強度に関する研究}, year = {1978} }
