Abstract

Beams are a rigid part of the structure of a building. This beam is specifically designed to be able to withstand and transfer loads to column. Beams without shear reinforcement will experience changes in behavior both in terms of strength and failure patterns.The shear capacity of existing reinforced concrete structures is often unable to meet existing requirements.This decrease in strength can be caused by increased load, strong shear that is inadequate in initial design and material damage due to natural factors. Many methods that have been done are by means of external bonded (EB) method and near-surface mounted (NSM) method. However, shear resistance using the EB and NSM methods is prone to structural failures due to the magnification of this method only to contain an epoxy attachment and its blanket. To overcome this problem the resistance method using deep embedment (DE) method have been proposed to reinforcement the shear capacity of existing reinforced concentrate structures.The purpose of this study was to analyze the shear behavior of reinforced concrete beams without shear reinforcement strenghtned by the DE method through finite element modeling.In this research, the existing reinforced concentrate structures put up the reinforcement by implant three kinds of steel carcass with 200 mm each gaps spread out shear beam. The maximum load result obtained from finite element analysis on reinforced concrete beams reinforced by the DE method was 29.09 kN. While the maximum deflection results obtained in finite element analysis was 10.1 mm. The failure model that occurs in the beam which is strengthened from the results of finite element analysis is the shear collapse.

Abstract

Bridges are infrastructure buildings that are commonly used and very functional in everyday. One of the structural components of the bridge is a reinforced concrete beam as a load bearer that will be forwarded to the foundation. The shear capacity of reinforced concrete beam structures sometimes cannot meet the existing requirements. This can be caused by increased loads, inadequate shear strength in the initial design and material damage due to natural factors. There are several methods that have been carried out to overcome the decrease in shear strength in beam structures, namely reinforcement methods by externally bonded (EB) and near-surface mounted (NSM). In reality, shear reinforcement with EB and NSM methods in implementation only relies on epoxy adhesion and concrete blankets, which still causes structural failure. The deep embedment strengthening method (DE) can be proposed as a shear reinforcement for reinforced concrete beams to overcome the previous problems. Reinforcement with DE method is a shear reinforcement that is reinforced in the core of reinforced concrete beams. This research was conducted by embedding 8 reinforcements vertically with a distance of 200 mm along the shear span. In this study, finite element modeling was carried out using ABAQUS. The results of finite element modeling with the DE method showed that the maximum load was 30.646 kN and the maximum deflection was 13.00 mm. The collapse model that occurs from finite element modeling on test specimens with DE reinforcement experiencing flexural failure.

Abstract

Fiber Reinforced Polymer is a combination of two main materials Resin Polymer (plastic) as a binder matrix and Fiber (fiber) as reinforcement. This material has three fibers, namely Carbon, Glass, and Aramid. Glass fiber was used in this study, because it has a greater strain compared to other fibers. This study aims to design reinforced concrete structures using steel reinforcement and GFRP as well as to compare the reinforcement requirements of each reinforced concrete. Calculation of reinforcement for steel reinforced concrete refers to SNI 1726-2019, while for GFRP reinforced concrete it is based on ACI 440 1R-2015. This research begins by collecting data in the form of a design structure drawing of a 6-storey hypothetical building, with a total building height of 23 m. The hypothesis building has the number of spans in the X-axis direction is 5 with a distance between columns of 6 m, while the number of spans in the Y direction is 3 with a distance between columns of 5 m. The column dimensions for all floors are 60 cm x 60 cm, while the beam dimensions are 40 cm x 40 cm. The thickness of the floor and roof slabs is 12 cm and the concrete quality is 30 MPa. For the calculation of structural loading, dead load, live load and earthquake load are used and the design of reinforcement for conventional steel reinforced concrete structures and GFRP is carried out. Steel reinforced concrete structures with GFRP reinforced concrete have differences in the amount and diameter of reinforcement required. For beam elements bearing steel reinforcement, 24 pieces of flexural reinforcement are needed with a diameter of 19 mm, while for beam elements, GFRP reinforcement requires 12 pieces of flexural reinforcement with a diameter of 1 inch to 1,128 inches. For the field area, steel reinforcement beam elements need 12 pieces with a diameter of 19 mm, while for GFRP reinforcing beam elements require 8 pieces of flexural reinforcement with a diameter of 0.875 inch to 1.128 inch. In column elements, steel reinforcement and GFRP reinforcement require the same amount of main reinforcement, which is 32 pieces. However, in terms of diameter, steel reinforcement requires 25 mm diameter reinforcement, while GFRP is 1 inch in diameter.

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

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.
