Study on the Integrated Vortex-Grid Clarification Process and Its Application Tong Zhengong1,a 1 School of Civil Engineering of East China Jiaotong University , Nanchang , China a E-mail: zzggtt@126.com Key Words: Micro-vortex flocculation, clarification ,water quality, integration Abstract.
Besides a quite dispersive arrangement and a higher investment cost due to the relatively high prices of equipments and materials for patented products, the guide wall built additionally between flocculation and sedimentation cannot totally avoid uneven distribution of water which affects the quality of water.The Domestic transformation technique for clarification tanks mainly includes the following three parts [4]: Firstly, add grid in the original reaction chamber to enhance the effect of reaction; Secondly, install the inclined tubes in the sedimentation areas to improve the precipitation efficiency.
In combination with the advantages of mechanical agitation clarification tank and Degremont high density sedimentation tank, Shanghai Municipal Engineering Design General Institute invented the centrally placed high density sedimentation tank process (SMEDI-I, SMEDI-II high density clarification tank).

Performance-Based Seismic Design of Reinforced Concrete Beam-Column Joints Bin Weia, Zhongguo Guanb and Jianzhong Lic State Key Laboratory for Disaster Reduction in Civil Engineering, Tongji University, Shanghai 200092, China awb030641@163.com, bguanzhongguo@mail.tongji.edu.cn, clijianzh@tongji.edu.cn Keywords: performance-based seismic design, reinforced concrete structure, beam-column joints, Mohr circle, softened stress-strain relationship of concrete Abstract.
To date, analytical methods proposed for the seismic design of joints are very few [2-5], and empirical formulas are typically adopted in engineering practices (e.g. the ACI 318M-08 building code [6]).
Softened constitutive model of cracked concrete Before cracking, concrete can be viewed as an isotropic material.
Cracked concrete can be viewed as an orthotropic material with biaxial loadings, in which the principal compressive strain ε2 is much smaller than the principal tensile strain ε1.

To be able to quantitatively describe the membrane behavior in terms of permeation fluxes and separation selectivity with the purpose to design separation and reaction units, good engineering models are needed.
Although the model slightly over-predicts the flux of CO2 in the whole temperature range investigated, the deviation from the experimental observation is considered to be minor, from an engineering point of view.

A New Similitude Analysis Method for a Scale Model Test Xianyue Gang1, 2, 3, a, Dengfeng Wang1, b, Xuejun Su1, c 1 College of Automobile Engineering, Jilin University, Changchun, China 2 School of Traffic and Vehicle Engineering, Shandong University of Technology, Zibo, China 3 Zhongtong Bus Holding Co., Ltd, Liaocheng, China a gangxianyue@sdut.edu.cn, bcaewdf@jlu.edu.cn, c8332299@163.com Keywords: scale model, FEM, FRF, similitude relationships, load scale rules Abstract.
The key point of this procedure is to establish the similitude relationship of modal parameters, frequency response functions and response characteristics between the scale model (SM) and the full size model (FSM).
(5) Supposing the SM and FSM have same material properties and similar boundary conditions, and their three dimensional sizes have a same scale ratio FS / LL=λ .
Because the SM and FSM have same material properties, they must have the same physical matrix FS DD = .
