1.Using the new numerical model for reinforced joint with consideration of the bond and slip between reinforcing bars and surrounding dam concrete, the 3D FEM nonlinear analysis for 292m high Xiaowan Arch Dan under design load working conditions of earthquake was conducted, and the effects of different kinds of reinforcement on stress, slip and transverse joint openings were studied.
2.In this paper the problem of optimum design of sliding isolation system under earthquake action modeled as Gaussian white noise process with zero mean is studied. On the basis of obtaining the sliding reliability function of mass point by using the stochastic equivalent linearization method and in accordance with a first-passage failure problem the optimum design of the sliding isolation system is approached by means of Lagrange multiplier method.
3.No propulsion occurs at this time although in the early phase of extraction momentum could be maintained.
4.Consistent with the rift of the Eurasian plate and thenorthwestward spread of the Pacific plate, the stress field from large scale of mantle convectiondisplays a skeleton of dumbbell shaped with sinistral compresso-shear at the north, dextralcompresso-shear at the south and slip in the middle. Energy converge strong at the south isattributed to the northward movement of the Indian ocean.
5.The example in the paper shows the efficiency of shift frequency together with inverse iteration to perform the dynamic topology optimization with frequency constrain.
6.Themes of the 6 th International Conference on Nearshore and Estuarine Cohesive Sediment Transport Processes include:1)interactions between cohesive sediment and turbulence:2)in situ observations of mud dynamics;
7.One dimesional Saint Venant hydraulic equations and two dimensional shallow tidal wave equations were employed to simulate the current jioning process between mainstream and its branch in a tidal estuary. On the basis of the current field, two dimensional convection diffusion equations under the orthogonal curvilinear and rectangular coordinates systems were empolyed to simulate the pollutants transportation jioning process, combining the method of Lagrange tracing water slices.
8.Some meso-scale systems can be produced to north and east side of the Plateau, such as the shear lines and southwest low vortexes to east side of the Plateau, and the weak high pressure north of the Plateau.
