Research Interests

Application of Three-Dimensional Finite Element Method to Design of Steel Structures

In order to propose the improvement in the design methods of steel structures, the three-dimensional finite element method using shellelements is employed. For the local stress analysis of a complicated steel structure such as a long-span bridge, the hybrid model which combines shell and beam element mesh is developed. By carefully in investigating the behavior of steel box-girder, the assessment of shear lag effects on stress and deflection is proposed.

Development of Run-off-River Small Hydropower Projects

The run-of-river small hydropower is considered as one of promising renewable energy sources in Thailand, since it gives less environmental and social impacts. The feasibility study of the hydropower projects of this type is performed by considering engineering, economic and environmental criteria. The geographical inforamtion system (GIS) is adopted as a tool for the present study.

Development of Efficient Organic Waste Composting System for Small and Medium Communities

Composting as the treatment of the municipal solid waste has getting more promising as it has lesser effect to the environment. However, in the developing countries, it has usually been looked over due to its unflavored processes, and lacking of technology. To eliminate such problems, this research project was emerged to develop a better composting system. A pilot plant was set up, and a series of experiment was conducted to study the optimal composting conditions, which would maximize its efficiency in actuality. This will follow by the feasibility study and Life Cycle Assessment (LCA) of the proposal as a sustainable consideration for the solid waste treatment method for the future.
