At present, EMA has become the most important method of vibration analysis in the mechanical engineering.
The key step of EMA is to get the eigenvector, the specific approach is as follow: The structural components to be tested should be manual incentive under the static state, and get frequency response function between the incentive points and the measurement points by measuring the exciting force and response signal, the frequency response function matrix was established and the structural modal parameters was gained by fitting the mobility function curve with modal analysis theory, so the modal model of the structure was established [7].

Introduction In recent years, high-rise diagonal grid structural systems are more widely used in engineering practice including Guangzhou West Tower, China Central Television and many other landmarks.
The former can predict structural force and deformation accurately under strong earthquake, but is constrained by uncertainties of ground motion input and high computation effort, so it is difficult to be popularized in engineering applications.
Results calculated by two different methods are compared and the applicability of Pushover on this structural system is examined, thus it can provide a reference for engineering applications.
Suitable material hysteretic model should be selected firstly.

Finite Element Analysis of Asphalt Overlays on Existing PCC Pavement under Heavy Traffic Loading SHEN Junmin1, a, ZHOU Yumin2,b and ZHANG Xiao1,c 1 Key Laboratory of Highway Construction and Maintenance Technique in Loess Area, Shanxi Provincial Research Institute of Communications, Taiyuan, Shanxi 030006, China 2Tongji University, Shanghai 200092, China ashenlpy@sina.com, b zhouym69@163.com, cxiaozhang2008@gmail.com Keywords: Asphalt Overlay, PCC Pavement, Rigid Pavement, Finite Element Method, Thermal stresses, Load Stresses Abstract.
Selecting the appropriate pavement structures, combination of aggregates and binder types are important decisions that engineers make on a routine basis.
Compressive stresses or strains occur at the top of the unbound materials, when the failure mechanism is likely to be something other than reflective or fatigue cracking.
Considering the relaxation effect of asphalt materials, temperature decreasing contraction equivalent modulus, and temperature curing equivalent modulus E1 = 0.13* 1200=156MPa, when calculating the load stress modulus, E1 is 1200MPa and asphalt concrete Poisson’s ratio v1 is 0.35.

Also, one-dimensional (1-D) semiconducting materials have a candidate for their potential applications in optoeletronic devices due to their large surface area to volume ratio [5-6].
It was reported that the existence of much oxygen vacancies, which can act as hole traps and play a key role in capturing the photogenerated holes, make the photogenerated hole difficult to recombine with the electrons, and prolong the lifetime of holes [14], so increase the the diffusion length of holes, hence, Loxygen > Lvacuum.
