The protection of the environment is not only a major strategic deployment to serve the long-term development of the country, but also a way for the Chinese nation to continue its economic development. In this regard, in the process of national infrastructure construction to promote economic and social development, the maintenance of the natural environment cannot be ignored. Highway traffic engineering is the key path to realize Chinas economic and social development, so it is also necessary to design it in a developmental way. Adding the idea of environmental protection into the design of highway engineering can not only change the natural environment along the highway to a great extent, but also make the environment around the highway engineering more harmonious and stable. This chapter will also make a preliminary discussion on the application of environmental protection ideas in highway traffic engineering design.展开更多

The modified augmented Lagrange multiplier methods (MALMM) for large-scale nonlinear constrained minimization are studied in this paper. The Lagrange function contains the penalty terms on equality and inequality constraints and the methods can be applied to solve a series of bound constrained sub-problems instead of a series of unconstrained sub-problems. The steps of the methods are examined in full detail. Numerical experiments are made for a variety of problems, from small to very large-scale, which show the stability and effectiveness of the methods in large-scale problems.展开更多

The basic equations of the method are first set up, and then the mode cut-off principle and the dividing principle are proposed. MATLAB is used for simulation in different frame structures. The simulation results demonstrate the applicability of this substructure method to civil engineering structures and the correctness of the proposed mode cut-off principle. Studies are also conducted on how to divide the whole structure for better computation efficiency while maintaining better precision. It is observed that the geometry and material properties should be considered, and the synthesis results would be more precise when the inflection points of the mode shapes are taken into consideration. Furthermore, the simulation performed on a large-scale high-rise connected structure further proves the feasibility and efficiency of this modal synthesis method compared with the traditional global method. It is also concluded from the simulation results that the fewer number of DOFs in each substructure will result in better computation efficiency, but too many substructures will be time-consuming due to the tedious synthesis procedures. Moreover, the substructures with free interface will introduce errors and reduce the precision dramatically, which should be avoided.展开更多
