Quadratic Programming Method

Based on the Compressive strength, workability and raw material consumption of concrete, a mathematical model is established for mix proportion design of high performance concrete (hereinafter referred to as HPC) with chlorine ion’s diffusion coefficient and per cubic meter cost as its optimized objectives. Matlab’s Sequential Quadratic Programming method is used for the solution of constrained nonlinear problems, with which the calculation and optimization of mix proportion of concrete are solved satisfactorily. HPC with optimized design can meet all requirements for its type and has obvious economic benefit.

In this paper, the main characteristic of definition, property, requirement of raw material, mix proportion design and performance improvement of high volume fly ash concrete (for short HVFAC) are summarized. The applications of HVFAC in dam, highway, building and port are introduced. The research results have shown that HVFAC have outstanding properties of physical mechanics, but some problems need to be further studied. It is believed that an operable strict corresponding technical criterion would be set down as soon as possible for engineering practice.

The main structure of passenger dedicated railway serves in complex physical environment, so its high durability is expected. In contrast to normal HPC applications, higher requirements are addressed for the application in passenger dedicated railway, which include control of raw material quality, selection of HPC design strength, and mix proportion design procedures. In this paper, the choice of HPC constituents, the principles of mix proportion design, and the design of HPC mix proportion for passenger dedicated railway based on overall calculation method are presented. Its application case in Quzhou Section of the Hangzhou-Changsha Passenger Dedicated Railway has shown that t the design of HPC mix proportion for passenger dedicated railway based on overall calculation method is effective and deserves popularization.

Keywords: High Performance Concrete, mix proportions, compressive strength , and durability Abstract. The use of concrete materials to date, remain a key ingredient in such construction work on the construction of building, bridges and infrastructure. One indicator is the increased production of readymix concrete which is nearly 16 billion tons in 2010. But the increased used of concrete, apparently bring the impact of environmental damage. This is due to the fact that production of raw materials contributes greatly to CO2 in the air. One effort to reduce such impact is to use of high performance concretes. Mix proportion of High Performance Concrete are strongly determined by the quality and availablity of local materials. The implications of research result from other countries can‘t be directly used. Therefore is need to the research on development of High Performance Concrete mix using locally available materials. In this research the mix proportions for f’c : 60 and 80 MPa are developed using local materials that are commonly used by readymix producers. The high Performance Concrete is developed based on compressive strength and durability. The result is expected to be applied to readymix industry particularly for construction use in Indonesia.

Quadratic Programming Method

The sequential quadratic programming method is introduced in arch dam shape optimization design. In the optimization computation, the arch dam volume is taken as objective function, and the calculation is realized by automatically considering loading process, equivalent stress computation and simulation of shape optimization for arch dam based on FEM. A parabola arch dam is used as a numerical example. The result shows that the optimized figure is much safer and more practical, which indicates that the SQP method is an effective way for optimization design of arch dam shape.
