In resent years, the unexpected phenomenon causes wide-ranging discussion in domestic academic and engineering.
According to the analysis in [3], if specimen is too long, under a horizontal shear, a bending plastic hinge will appear due to the large eccentric compression on the column, but it will be actually far from the requirement of the general civil engineering if the specimen is too short.

Recently, a type of data fusion technique based on expert knowledge and machine learning to define the structure of Bayesian network has been applied in the field of environmental engineering widely, taking a proportion of 43.9%.[10] The reason of the widespread use of it is that it synthesizes the advantages of expert knowledge and machine learning, avoiding the disadvantages of only choosing one of them.
Accurate and stable travel mode choice prediction may help engineers establish appropriate traffic policies which may contribute to cutting congestion.
