The research provides a basis for engineering application and theoretical analysis of the structural system.
The scholars at home and abroad have carried out some studies on patterns and effects of stiffeners[2~4], but they have not done much research on the mechanism of cooperative work between semi-rigid connection and steel plate shear wall with cross stiffeners, this paper carried out experimental studies on seismic behavior of this structure system under cyclic loading and provided basis for engineering application and theoretical analysis of the structure.

Assessment of Structural Integrity for a Concrete Runway by Seismic Techniques Sung-Ho Joh1,a and Tae-Ho Kang1,b and Soo-Ahn Kwon1,c 1 Department of Civil Engineering, Chung-Ang University, AnSeong, Gyeong-Gi Do, 456-756, Rep. of Korea 2 Korea Institute of Construction Technology, Dae-Hwa Dong, IlSan-Gu, Go-Yang, GyeongGi-Do, 411-712, Rep. of Korea a shjoh@cau.ac.kr, bthk0102@ms.cau.ac.kr, csakwon@kict.re.kr Keywords: Concrete Runway, Seismic Methods, Nondestructive Tests, Forensic Engineering Abstract.
The validity of the integrated approach was also proven in lieu of forensic engineering for concrete runway pavements.
As summarized in Table 2, seismic techniques can evaluate engineering parameters such as elastic modulus, lateral variation of modulus, slab thickness and dynamic stiffness.
This field application highlights the merit of the integrated non-destructive seismic method, and provides feasibility of the procedure as a tool for forensic engineering.

Prospects for Using Carbon Nanotubes in Precision Instrument Engineering A.
Thus, use of nanotubes in precision instrument engineering can solve a number of problems, such as increase in reliability, accuracy, durability, weight and size reduction, etc.
As the object of our research we have chosen FOG forming a part of SINS [20] intended for use in control, navigation and stabilization systems of vehicles of space and civil purposes, in which traditional optical fiber is "replaced" with microstructured fiber with capillaries filled with air and thermally conductive CNTs nanoparticles.

Leakage is a difficult problem influenced the quality of engineering.
GT is as an example, to analysis the method of construction technology and quality inspection in engineering.
The article introduces the construction technology and quality inspection method of GT, hope to provide help to improving the engineering quality of waterproof construction.
Because of the excellent performance characteristics, GT can solve leakage problems such as aging, cracking and pollution, be widely used in waterproof of building roofing, basement, kitchen, toilet, swimming pool, civil air defense engineering, subway, tunnels, reservoirs and other constructions.
Waterproof construction of GT on building roof should be consistent with the "technical code for roof engineering" (GB50345-2004).

Elastic Critical Buckling Modes and Stress of Cold-formed Thin-walledLipped Channel with Multiple Intermediate Stiffeners MA Guangyue whutma@whut.edu.cn (School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070) Key words: multiple intermediate stiffeners, cold-formed thin-walled lipped channel, elastic critical buckling modes, elastic critical buckling stress Abstract: Elastic buckling modes of cold-formed thin-walled steel member have three relevant types: local, distortional and global.
The complicated and important thing is to differentiating buckling modes and resolving buckling stress for engineers.
The theoretical analysis coincide exactly with the experimental results, it can be used as a reference for engineers.
In recent years, low rise of cold-formed thin-wall steel structure building system used a lot in China,for instance, the MET FRAME system in Australia is the structural system used multi-ribbed walled frame and trussed beam (Fig.1).Eachstructural memberis standardcomponent, usual shape of section is lipped channel with multiple intermediate stiffeners (Fig.2).Bearing capacity of single standard member can be calculated by effective width method or direct strength method after buckling modes and stresses be given.However,there are three elastic correlative buckling modes, so engineer is difficult to finish the job.Therefore, this paper attempts to provide buckling modes and buckling stress of the standard member by using cold-formed steel theory and testing , in order to be used directly for design engineering.
