Abstract

This literature review presents a comparative analysis of various applications of the Finite Element Method (FEM) in the modeling and analysis of civil engineering structures, with a specific focus on cold-formed steel (CFS) connections and reinforced concrete columns. The primary aim of this research is to evaluate the precision and reliability of computational simulations in replicating complex structural behaviors under diverse loading conditions. The review methodology was conducted through a systematic selection of studies published between 2015 and 2025 that examine the effectiveness of FEM in comparison to analytical and experimental approaches. Aggregate results indicate that FEM exhibits a deviation of 25–29% from experimental outcomes in modeling Haunched Gusset Plate (HGP) connections within CFS structures, while effectively predicting bolt hole failure modes. In reinforced concrete columns, modeling using the Concrete Damage Plasticity (CDP) approach demonstrates an increase in axial capacity by 115–121% due to variations in stirrup configurations. Overall, this review confirms that FEM is an accurate and efficient predictive tool for analyzing the nonlinear behavior of structures and plays a vital role in structural optimization and enhancing the design reliability of modern engineering.

Abstract

Collaboration between universities and communities plays a crucial role in addressing environmental issues, particularly in the management of organic waste in rural areas. This article presents the results of a community service program by the University of Riau through the Kuliah Kerja Nyata (Kukerta) Tematik Literasi program in Suak Lanjut Village, Siak Regency, Riau. The program aimed to improve environmental health by introducing simple technologies, such as eco enzyme and biopori absorption pits. The method used was a participatory approach combining qualitative and quantitative methods through three stages: The first stage involved field observations, interviews with housewives from the PKK, and an analysis of data from the Siak Regency Environmental Protection Agency (2023), which showed that 67% of waste was organic material. The main activity involved 25 participants and three sessions: a lecture, a demonstration of eco enzyme production, and a practice of biopori creation using plastic bottles. The results showed an increase in environmental awareness. The positive impacts are reduced methane gas emissions, increased production of compost, and eco ezymes that are environmentally friendly. The program aligns with the Tridharma of Higher Education, supports the Siak Green program, and contributes to SDG goals 3 and 12.
