Performance Prediction of Hybrid Bamboo-Reinforced Concrete Beams Using Gene Expression Programming for Sustainable Construction

Abstract

The building and construction industry’s demand for steel reinforcement bars has increased with the rapid growth and development in the world. However, steel production contributes to harmful waste and emissions that cause environmental pollution and climate change-related problems. In light of sustainable construction practices, bamboo, a readily accessible and eco-friendly building material, is suggested as a viable replacement for steel rebars. Its cost-effectiveness, environmental sustainability, and considerable tensile strength make it a promising option. In this research, hybrid beams underwent analysis through the use of thoroughly validated finite element models (FEMs), wherein the replacement of steel rebars with bamboo was explored as an alternative reinforcement material. The standard-size beams were subjected to three-point loading using FEMs to study parameters such as the load–deflection response, energy absorption, maximum capacity, and failure patterns. Then, gene expression programming was integrated to aid in developing a more straightforward equation for predicting the flexural strength of bamboo-reinforced concrete beams. The results of this study support the conclusion that the replacement of a portion of flexural steel with bamboo in reinforced concrete beams does not have a detrimental impact on the overall load-bearing capacity and energy absorption characteristics of the structure. Furthermore, it may offer a cost-effective and feasible alternative.

Influence of pozzolanic addition on strength and microstructure of metakaolin-based concrete

“…smaller than that of MB-1 and cement mortars containing MS. Because of the filler effect, finer NS particles improve packing and lower flow [30]. We found that the flow of mortar reduced as the NS content increased in the case of OPC-MK-NS.…”

“…Compared with MB-1, the flow of cement pastes containing MS dropped to MB-2 (7.30%), MB-3 (11.70%), MB-4 (13.20%), MB-5 (15.60%), and MB-6 (18.55%). The flow of cement mortars containing NS was found to be smaller than that of MB-1 and cement mortars containing MS. Because of the filler effect, finer NS particles improve packing and lower flow [ 30 ]. We found that the flow of mortar reduced as the NS content increased in the case of OPC-MK-NS.…”

“…Furthermore, new methods have been employed to enhance the sustainability of concrete [16][17][18][19][20]. One of these methods is the application of waste materials as a replacement for aggregate or cement [21][22][23][24][25][26][27][28][29][30]. The use of waste materials as a replacement for aggregate significantly reduces the utilization of raw materials [31][32][33][34][35][36].…”

“…However, if it is not, the chromosome will be reiterated by numerous processes such as mutation, replication, transposition, and recombination to create new ETs [39,67]. The same evaluation process is repeated until the best solutions or predefined fitness are achieved [68][69][70]. Figure 9a shows an example of chromosome structure in ET.…”

Behavior of Fibers in Geopolymer Concrete: A Comprehensive Review

“…A large number of natural resources are used for the production of PC like fossil fuels, limestone, electricity, and natural gas [8]. The manufacturing of PC is a very high-temperature and energy-intensive process, which results in an increase in carbon dioxide (CO 2 ) footprint in the atmosphere [11][12][13][14][15][16][17][18][19][20][21][22]. The carbon emissions are primary factors contributing to global warming.…”
