摘要：With the rapid improvement of modern numerical computation technique, the analysis methods of large scale concrete structures have been progressing quickly as well. The demand for more precise and complete understanding of the constitutive materials of civil structures is urgent. Knowledge of the characteristics of concrete subject to dynamic loading is of fundamental significance to the seismic safety evaluation of large scale structures. Based on the literatures available, the major factors affecting the dynamic properties of concrete are systematically discussed. The most important factors such as concrete grade, specimen size, curing and working environment, and test methodology are analyzed in detail. The weakest links in concrete dynamic, study are indentified as multi-axial stress state,severe curing/working environment,complex loading history and cyclic reverse loading,ete,which are also of cructial importance to the dynamic failure of the large scale structures in civil engineering. More extensive study is needed in these areas.
