Modeling of Fretting Wear Based on Cumulative Plastic Strain and Saturated Shear Stress Yong Liu1,a, Jinquan Xu 1,b, Yoshiharu Mutoh2,c 1 Department of Mechanics, School of Civil Engineering and Mechanics, Shanghai Jiaotong University, 800 Dongchuan Road, Minhang, Shanghai 200240, People's Republic of China 2 Department of Mechanical Engineering, Nagaoka University of Technology, Kamitomioka 1603-1, Nagaoka, 940-2188, Japan a liuyong004@sjtu.edu.cn, bjqxu@sjtu.edu.cn, cmutoh@mech.nagaokaut.ac.jp Keywords: fretting wear; cumulative plastic strain; fretting fatigue Abstract.
From the viewpoint of engineering application, a simple model of fretting wear, with global mechanical parameters or some other parameters which are easy to obtain, is strongly expected rather than that with transiting local parameters which only can be obtained by very complicated computations.
From the viewpoint of engineering application, however, a simple model of fretting wear, with global mechanical parameters which are easy to obtain, is strongly expected rather than that with transiting local parameters which only can be obtained by very complicate computations.
It is obviously that shear stress on contact interface at extreme state is easy to be obtained and it also catches the characteristic of the fretting wear as is presented above, thus choosing the shear stress as the parameter evaluating fretting wear is appropriate in engineering application.

Seismic Performance of Concrete-Filled Square Tubular Column and Reduced Steel Beam Joints Yanli Guo1,a，Xingyou Yao2,b 1 College of engineering, Guangdong Ocean University, Zhanjiang, China 524088 2College of civil engineering, Tongji University, Shanghai, China 200092 aguoyanlichd@126.com, byaoxingyoujd@163.com Keywords: Concrete-Filled Steel Square Tubular Column Beam-Column Joint; Reduced Beamsection, Nonlinear FEM; Seismic Performance.
Two new kinds of joints with holes in flange or flange and web are suggested to use for concrete-filled steel square tubular column and reduced steel beam in this paper, Seismic performance of these two new kinds of joints under monotonic and cyclic loading are analysis by finite element method (FEM), and the dimension of the new reduced beam joints with high stiffener, load-carrying capacity, good ductility, and energy- dissipating ability are suggested for engineering.
Four kinds of new RBS joints cutting hole in flange or flange and web are suggested to use in engineering.

Over the past years, the penetration into concrete targets has received much attention due to its extensive application in both the civil and military domains, and now remains to be an active research field[4].
Due to this property, SFRPMC is attractive for engineering application.
Several applications are foreseen in which steel fiber reinforced polymer modified concrete will give the designer or engineer greater flexibility in choosing material for new construction, upgrading structures and repairing cracked or cratered roads, runway and structures.

This has made it increasingly important for engineers to estimate accurately the dynamic effects of vehicles on the serviceability of existing bridges and in the design of new bridges.
Because of the restriction of theoretical level and computational method in early stages, dynamic loading test of bridge structure was extensively applied to engineering practice.
