Abstract

Capacity building for campus sustainability has been recognized as a process of strengthening the university stakeholders’ skills to minimize the negative impacts of current crises and emerging challenges. While many universities emphasize capacity building through research and education activities, most, if not all, neglect activities for non-academic staff. Without the necessary capacity, the universities might not be able to realize their development plans. To address this issue, Chulalongkorn University developed a capacity building program called “Beyond Leading Changes” in 2021 which consists of three modules. The first aims to provide SDGs knowledge and raise awareness on the local and global challenges. The second focuses on the design thinking process in which participants were asked to empathize, define, and ideate potential solutions to sustainability problems. The last module utilizes the project-based leaning approach in which the skills were developed through engaging projects set around real-world problems. 70 supporting staff from various units completed the program which resulted in many interesting pilot projects that cover a wide range of issues. Nevertheless, the challenge remains to make the program more accessible and inclusive.

Abstract

This study conducts a numerical analysis on the shear performance of reinforced concrete beams retrofitted with fiber-reinforced polymer (FRP) bars with embedded through-section (ETS) technique. The study uses 3D nonlinear finite element method (FEM) and evaluates the shear features of ETS-FRP-strengthened beams in failure modes, shear capacity, stiffness, and ductility. The FE analyses consider the effects of key design parameters, including transverse steel stiffness (Eswρsw), ETS-FRP bar stiffness (Efρf), compressive strength of concrete (f’c), beam geometry, and the values of shear span-to-effective depth (a/d) ratio. Consequently, ETS-strengthened beams with higher concrete strength (f’c) or greater total rigidity of ETS and transverse reinforcement (Efρf + Eswρsw) showed notable improvements in stiffness and load-carrying capacity, with average increases exceeding 20%. The enhancement in shear strength from increased shear reinforcement stiffness is less pronounced in specimens with high concrete strength than in those with lower strength. ETS-strengthened beams with T-shaped sections exhibit more effective performance and safer failure modes. An enhancement in the a/d ratio reduces the stress in ETS bars but results in more ductile failures. This study also proposes a new analytical formulation for determining the maximum shear resistance of ETS-intervened beams, accounting for all failure modes. The model achieved an average predicted-to-tested shear maximum force ratio of 0.93 along with a coefficient of variation of 26%, demonstrating improved accuracy compared to existing models.
