Abstract

The development of science, especially in the field of construction, has produced various innovations, one of which is on wall materials that can support the effectiveness of work, especially in the construction of multi-storey buildings. It is realized that wall material can affect acoustic, thermal, and visual comfort levels. The choice of wall material has a direct impact on the environment where the use of environmentally friendly materials can reduce carbon footprint and construction waste. This study aims to analyze the effectiveness of the use of wall materials such as red brick, adobe and lightweight brick in terms of structural strength, cost and service life of the structure. To compare various alternatives, an assessment of each alternative consequence is carried out using a decision-making system. The results of the analysis showed that alternative 3 using lightweight brick obtained the highest value so that alternative 3 became the top priority of other alternatives to optimize the construction of high-rise buildings.

Abstract

This study aims to analyze and validate the flexural behavior of reinforced geopolymer concrete beams compared to conventional concrete using a numerical approach through the Finite Element Method (FEM) with ANSYS software. The simulations were based on geometric and material parameters from previous experimental studies, including those by Abraham et al. (2013), Dattatreya et al. (2011), and Ojha et al. (2022). The simulation results indicate that the load–deflection behavior, crack distribution patterns, and flexural capacity of geopolymer concrete beams are comparable to those of conventional concrete beams. Validation against experimental data shows small deviations in both ultimate load and maximum deflection, confirming the accuracy of the numerical model. Crack propagation in the flexural zone also demonstrates similar characteristics, suggesting that geopolymer concrete is a viable alternative structural material. This research contributes to the development of numerical modeling to support the implementation of geopolymer concrete in sustainable construction.
