The Application of the Technology in Reinforced Frame Beam complex material Hang yue1,a Shuai liu2,b 1Huanghuai University 2The 403 team of metallurgical geology exploration bureau in liaoning province E-mail:liushuaimf88@126.com Keywords : carbon fiber, reinforcement, frame beam, repairment Abstract: The article tries to describe the application of CFRP in frame beam used in the reinforce of civil engineering through some concrete engineering examples.
As there doesn’t exist construction acceptance criteria and other specification of carbon fiber used in the reinforced repairment at home, thus in this article, the writer aims at analysising the usage of carbon fiber in the construction of civil engineering structures.
The reinforcement technology of carbon fiber has made the full development in the field civil engineering in recently years. compared with the traditional structural reinforcement method, it has the following advantages, such as high strength, efficiency construction cowen; ency, and a wide range of use etc.
Conclusion Practice has proved that the carbon fiber reinforcement technology is ideal for the reinforcement of concrete structures and components effect of FRP reinforced concrete structure has broad application prospects in the field of civil engineering.
However, due to the civil engineering sector of FRP started quite late, the theory is not yet mature, many aspects need further study.

We solve interaction between the foundation base and the subsoil in civil engineering quite often.

Here we summarize the development and status of AM technology, the underlying problems and its application perspective on civil aircraft.
Additive manufacturing technology, which involves a comprehensive integration of materials science, mechanical engineering, and laser and welding technology, is regarded as an important revolution in manufacturing industry.
In 2013 American society of Automotive Engineers (SAE) developed the aviation material standard Ti-6Al-4V powder AMS4998E.
With the improvement of people's living standard and the progress of technology, the public economy of the civil aircraft, environmental protection have become increasingly demanding, this puts forward higher requirements to the manufacturing technology of civil aircraft.
Lately, China has made significant progress in the development of AM technology[12], particularly for the civil aircraft.

The failure of civil engineering structure will lead to heavy losses.
Introduction During the service processing, due to using or environment and other reasons, civil engineering structures often produce and exist the different degree damage and even cause structural collapse.
So the relative wavelet entropy may be used to identify structural damage location Tab.3 The damage time scenarios of test beam Scenarios Damage moment Simulation state Scenario 1 4th second discharge a quality block Scenario 2 1.8th and 3th second discharge two quality blocks Fig.10 The bar chart of damage location of test beam under three scenarios Fig.11 The bar chart of damage time of test beam Acknowledgements This work was financially supported by the China National Natural Science Foundation (50878198) References [1] Dajian HAN, Wendong WANG: Journal of South China University of Technology (Natural Science), Vol. 31(1) (2003), p. 91-96, In Chinese [2] Zengshou SUN: Study on Wavelet-based Damage Identification Method for Civil Engineering Structures [D], Fuzhou, China, 2006, In Chinese [3] Jian GUO, Zhengwei GU and Bingnan SUN: Engineering

The experimental investigation at the Faculty of Civil Engineering SUT (STU) in Bratislava was planned for slender concrete columns made of different concrete strength classes - C45/55, C70/85 and C100/115.
The experiments were realized at the Faculty of Civil Engineering SUT in Bratislava with cooperation of ZIPP Bratislava LTD Company.
When the characteristic strength of concrete reached 60%, experimental columns – samples were conveyed to the laboratory of Civil Engineering Faculty SUT (STU) Bratislava.
Experimental verification After these theoretical and practical preparation, the concrete columns were tested in the laboratory of the Civil Engineering Faculty SUT (STU) Bratislava.
