Abstract

This study aims to investigate the impact of masonry infill walls on the behavior of reinforced concrete frames under seismic loads. Traditionally, masonry walls have been considered non-structural elements; however, their interaction with the overall structural behavior is crucial, especially in earthquake-prone areas. Understanding how these walls affect structural performance is essential to ensuring safety and effectiveness in design. This study employs a comprehensive literature review to analyze various factors influencing the performance of masonry walls in reinforced concrete structures. The key aspects examined include material properties, lateral load capacity, energy dissipation ability, and structural deformation. An evaluation is conducted on experimental test results from previous research. The findings reveal that the addition of masonry infill walls significantly increases the lateral stiffness and load-bearing capacity of reinforced concrete frames. Specifically, the study shows that structures with solid masonry walls exhibit a base shear force 1.2 times greater than those with clay brick walls. However, the study also highlights the reduction in deformation due to the brittle nature of masonry, which can lead to shear failure under ultimate load conditions.

Abstract

Liquefaction is the transformation of soil into a liquid. The vibrating table in this study moves in a horizontal direction and the opposite manner in a vertical direction utilizing modelling. Acceleration variations of 0.25 g and 0.32 g were employed. The dirt was 10 centimetres thick. The sand clusters were 15 cm thick, with differences in debris gradient size and water surface on the sample. The uniform load that was employed was 40 kg/m2. Examine the drop of the ground surface and the rising of the porous water for signs of liquefaction. A 0.5mm diameter glass pipe was used to measure the porous water pressure. The test findings revealed that with higher acceleration, effective vertical voltage, and porous water ratio values, the rate of particle graduation has a major influence on the occurrence of liquefaction potential. The test results revealed that poorly graduated fine sand experienced maximum effective vertical stress and elevated porous water ratio values (Ru), whereas well-graded sand tended to be more stable.

Abstract

This research evaluates the impact of adding masonry walls on the stiffness and stability of building structures, focusing on pushover analysis and seismic behavior through a review of several journals. According to the research conducted by Hutajulu et al. (2019), masonry walls serve as significant structural elements rather than mere non-structural components. Through numerical analysis of the curves in the study, it was found that structures with masonry walls have a higher peak stiffness of 27.362 kN/mm, capable of withstanding a maximum load of 7490.93 kg with a displacement of 15.058 mm, compared to portals without walls, which only achieve a peak stiffness of 10.386 kN/mm and can withstand only 1451.91 kg. The stiffness difference between both portals reaches 66.242%. Similar studies by Majumder et al. (2017) and Mukhlis et al. (2022) also yielded comparable results, indicating that structures or portals accounting for the addition of walls exhibit significantly greater stiffness compared to those without walls, with stiffness differences exceeding 50%. In addition to its effect on stiffness, the addition of masonry walls also impacts the base shear capacity that the portal or structure can bear, as the inclusion of walls allows for greater lateral forces to be resisted compared to conditions without walls. For instance, in Hutajulu et al.'s (2019) study, the base shear for bare frames was only 14.025 kN, while infilled frames reached as high as 74.918 kN. These findings demonstrate that incorporating masonry walls into structures or portals enhances their resistance to lateral loads compared to those without masonry walls, contributing additional strength, stiffness, and earthquake resilience to the structure. Therefore, masonry walls should be treated as integral structural elements in building design to ensure safety and optimal performance under various load conditions.

Abstract

Balok beton bertulang merupakan elemen struktural yang berperan penting dalam menahan beban vertikal serta mentransfer gaya ke elemen lain dalam sistem struktur. Seiring dengan meningkatnya tuntutan kekuatan dan daya tahan struktur, berbagai metode perkuatan telah dikembangkan, salah satunya adalah penggunaan steel plate. Teknik ini digunakan untuk meningkatkan kapasitas lentur dan geser balok beton bertulang dengan cara menambahkan pelat baja pada permukaannya. Metode perkuatan dengan steel plate dilakukan melalui beberapa tahapan, termasuk persiapan permukaan beton, pemasangan pelat baja menggunakan baut atau perekat, serta pengujian untuk mengevaluasi efektivitasnya. Pengujian yang dilakukan pada balok yang diperkuat menunjukkan adanya peningkatan kapasitas beban serta penurunan defleksi dibandingkan dengan balok tanpa perkuatan. Selain itu, penggunaan pelat baja juga membantu memperlambat munculnya retak serta meningkatkan kekakuan struktural. Meskipun efektif, teknik ini memiliki tantangan, seperti risiko delaminasi akibat lemahnya ikatan antara baja dan beton, serta kemungkinan berkurangnya daktilitas struktur. Oleh karena itu, diperlukan teknik pemasangan yang optimal untuk memastikan bahwa steel plate dapat memberikan hasil yang maksimal dalam meningkatkan kapasitas struktural balok beton bertulang.

Abstract

The collapse of concrete structures due to excessive loads is a serious issue that can lead to significant losses, both in terms of materials and human safety. This phenomenon is often caused by a weak understanding of the load mechanism acting on structural elements, including the interaction behavior between reinforcing steel and concrete. In both new and old buildings, damage to certain structural elements, especially beams, is inevitable. This damage occurs due to design errors in the building, mistakes during construction execution, or changes in the building's function. With the advancement of technology, there are now reinforcement methods for beam structural elements, including Steel Solid Plate, Jacketing, and Carbon Fiber Reinforcement Polymer (CFRP). These three methods will be evaluated based on deflection and strength.

Abstract

Reinforced concrete columns are critical structural elements that support vertical loads in buildings. Over time, these columns may experience a reduction in capacity due to aging, seismic activity, fire exposure, or changes in building function. Concrete jacketing is one of the most widely used strengthening techniques to restore and enhance the performance of damaged or weakened columns. This study presents a comprehensive literature review to evaluate the effectiveness of concrete jacketing in improving the axial, shear, and flexural capacities of reinforced concrete columns. The mechanism of this method is explained through the enlargement of the cross-sectional area, installation of additional reinforcement, and confinement effects. The review also explores material innovations such as the use of self-compacting concrete (SCC), the addition of fly ash, and alternative reinforcement materials like bamboo and natural fibers. Key implementation aspects, including surface preparation, reinforcement detailing, and casting methods, are also analyzed. Furthermore, the study compares concrete jacketing with other strengthening methods in terms of cost-effectiveness and applicability. The findings indicate that concrete jacketing is a practical, economical, and effective strengthening solution, particularly for buildings located in seismic-prone areas or undergoing functional changes.

Abstract

Damaged buildings require structural reinforcement. This journal uses external restraints with Natural Fiber Reinforced Polymer (NFRP) material because Fiber Reinforced Polymer (FRP) material requires relatively expensive costs and a production process that is not environmentally friendly. This research review aims to determine the behavior of confined concrete with external Natural Fiber Reinforced Polymer (NFRP) and the increase in compressive strength due to confinement. The test is carried out by providing an axial load on the concrete test object which is restrained by NFRP. NFRP restrained specimens are made by wrapping the entire concrete in a circle using natural fibers and adhesives. The results obtained from this research review are the compressive strength of confined concrete using several types of natural fibers such as jute, hemp, cotton, abaca and basalt, it is found that the type of fiber and the number of layers of NFRP affect its compressive strength. NFRP showed a significant restraining effect on increasing the compressive strength and increasing the ductility of the concrete. The increase in strength and ductility will increase with an increase in the number of layers of Natural Fiber Reinforced Polymer (NFRP).

Abstract

Retrofitting is a key strategy to restore or enhance the performance of reinforced concrete structures damaged by overloading, deterioration, fire, or seismic events. This study synthesizes findings from three approaches: a literature review, experimental testing using FRP on reinforced beams, and a case study involving post-fire strengthening with CFRP and steel bracing. Various methods epoxy injection, concrete jacketing, FRP, CFRP, and bracing are compared based on effectiveness, structural impact, and application context. Results indicate that CFRP and FRP significantly improve flexural and shear strength, epoxy injection is suitable for minor cracks, and concrete jacketing enhances capacity substantially. For fire-damaged structures, combining CFRP and steel bracing effectively reduced drift ratios and restored structural integrity. SAP2000 modeling results align closely with experimental data, confirming its reliability in retrofit analysis. The study highlights that retrofit selection must consider damage level, element type, and cost-efficiency.
