Introduction Structural Health Monitoring and damage detection of Civil Engineering structures has become in recent years a major issue: the need of keeping the performances and evaluating the residual safety for aged or damaged structures has led to an increase in the development of non-destructive monitoring techniques [1-3].
Since in structural engineering applications often natural excitation sources cause transient or non-stationary responses, the use of specific signal processing tools is needed in order to extract reliable information about possible non-linearities.

Experimental investigation of seismic behavior of a new type masonry walls Wei Chen1,a, Fangbo Wu1,b, Xuhong Zhou1,c and Hailin Huang1,d 1Department of Civil Engineering, Hunan University, Changsha, China acw9876@hnu.edu.cn(corresponding author), bwfbprof@163.com, czhouxuhong@126.com,dhhlvsgenius@163.com Key words: Masonry walls; concrete horizontal-holed hollow block; static cyclic tests; seismic behaviour Abstract.
Despite of their broad applications, the hollow blocks with vertical holes have some shortcomings in engineering applications.
It is obvious that a window opening could significantly reduce the load carrying capacity of a wall and this must be considered in engineering designs.
