SMART COMPUTING IN CIVIL ENGINEERING RESEARCH GROUP (SCCE)

1.    Introduction
Along with the development of computer science, intelligent computing methods based on artificial neural networks and machine learning are increasingly being applied in various engineering fields, particularly in civil engineering. Many problems in civil engineering still lack optimal solutions through traditional methods such as analytical, experimental, and numerical methods (finite element method, discrete element method, etc.). Some typical problems include:
o    Estimating the ultimate axial load capacity of pile foundations.
o    Evaluating the stability of geotechnical problems: tunnel construction, slopes, retaining wall structures, and shallow foundations.
o    Assessing the residual strength of corroded reinforced concrete structures.
o    Predicting wave height impacting coastal structures.
o    Developing an optimized method for the sustainable design of reinforced concrete structures and construction materials.
o    Offshore geotechnics and geophysics.
o    Soft soil improvement.
Applying intelligent computing methods can help bridge current research gaps while providing optimal solutions for civil engineering practices in Vietnam.
2.    Vision and Mission
SCCE aims to become a leading research group in intelligent computing applications in civil engineering. The research directions of the group follow two main criteria:
•    Scientific novelty and technological impact: The research should be pioneering and have high potential for practical applications.
•    Practical applications: Research problems should stem from real-world demands in civil engineering and be applicable in practice.
Additionally, SCCE is committed to building an academic research environment with high integrity, responsibility, and a long-term goal of serving as a bridge between scientists and enterprises to promote technology transfer.

3.    Research Directions
