Introduction In-situ health monitoring is one of the greatest challenges in several industries such as aerospace, marine, automotive and civil engineering.
Structural health monitoring (SHM) is generally defined as the process of implementing a damage identification strategy for aerospace, civil and mechanical engineering infrastructure [2].
However for such repairs to be certified by the Civil Aviation Authorities on-line monitoring techniques are urgently needed.

Study on Structural Morphology of Expressive Force of Architecture XU Wei-qi1,a, DUAN Xiang1,b, WU Ding-feng1 and YU Chen1 1School of Civil Engineering and Architecture，Wuhan Polytechnic University，China,430023 axuweiqi00608@163.com, bjintang28@163.com Keywords: architecture expression, structural morphology, architectural creation Abstract.By discussing the structural form’s effects on the architectural modelling,this paper elaborates the relationship between structural form and architectural modelling essential factors,and reveals the aesthetic characteristics of the structural morphology as well as how to express structural aesthetics value.Results show that the creative way to achieve the unification of architectural modelling and structural form is basic approach architectural design’s structure manifestation,and sevaral methods of this manifestation are also presented.
Introduction With the growing complexity of architecture design, the relationship of architects and structure engineers should be“mutual need,cooperation and mutual assistance.”Therefore,the harmony of architecture and structure in the design process prevent producing excellent works.Generally speaking,The division of architecture and structure is promoting the development of both sides,but losing the harmony of beauty between them.These problems further cause the result that the organic connection between them is destroyed and this is against the basic value orientation of architect.
Tange,who has been searching for combination point of structural form,material characteristic,structure technology and plastic arts,in order to endow architectural modeling with the beauty of poetry and rhythm,whose architectural works is the integration of art, science and technology.However,although technology was the foothold of his design methodology,its main feature lied in imaginative poetic effects.Kenzo Tange makes the logic of technology and formal beauty in architecture well integrated by scientific analyse,mathematical demonstration,bionic algorithm in structure and other methods.So,shaping morphology and solving the engineering problems can be carried out at the sanme time.
Technique of Regular Geometrical Patterns.Geometry is the elementary knowledge for architect and engineer to implement designing and function shaping.Regular geometrical patterns is an indispensable tool to mold the specific space environment,buildings and its structure form.
